CAPACITIES AND LIMITATIONS
AERIAL CAPACITIES
DANGER: Aerial operating capacities are governed by the aerial load chart installed at the Aerial control station. Any deviation from these rated capacities could cause death or serious injury and /or structural failure or the aerial.
As the operator of an aerial ladder, the well being of various personnel rests with your performance skill and ability to make proper judgments “on the spot’ as conditions demand. These factors make it all the more imperative that you are not only aware of your limitations, but also aware of the physical and structural limitations of the apparatus. Some of the following limitations appear on the Aerial Load Chart and are repeated here for informational purposes only.
DANGER: When operating Aerial Ladders, refer to the Aerial Load Chart for rated capacities and related information. Never rely on memory!
1. Load capacities are established at maximum permissible extension and operation throughout 360 degrees, with outriggers fully extended and set, turntable level, waterway drained and aerial ladder unsupported.
2. Full, rated capacities are allowable on grades up to, but not including, 6%/3.5 degrees . On grades between 6 and 14%/3.5 and 8.0 degrees, capacities are reduced by 50% (one-half).
3. Wind, ice, and other factors affecting stability, as well as strength of supporting surfaces and skill of the operator, must be considered when utilizing the aerial at its fullest potential.
4. Certain capacities are limited by structural strength, therefore, stability factors (as evidenced by the apparatus tipping) must not be relied upon as the capacity limitation.
5. Reduction in load capacities must be made to compensate for ice and/or snow accumulation.
6. Capacities are established for unit based on standard unit configuration. Substitution and/or addition of non-standard equipment will void all warranties and invalidate any liabilities.
WARNING: Capacities are established with no additional equipment at the tip (other than “as delivered” items). The weight of the tip equipment (nozzles, pike poles, axes, ladders, etc.) must be deducted from the tip load capacities.
NOTE: Due to additional weight imposed on units loaded with auxiliary equipment at the tip, lift circuit relief valves may restrict a fully extended aerial from being at horizontal or low angles.
READING YOUR CHART
The load chart presents a graphic display of the aerial ladder apparatus’ load lifting and weight distribution limitations. The chart is representative of both ladder and water tower operational capacities, as well as combined operational capacities. Basic operating precautions and emergency shutdown instructions are also included in the chart as applicable. When used with the aerial elevation indicator, the aerial load chart enables the operator to determine the rated load capacity of the aerial under specific load conditions.
WARNING: The only applicable load limitations and capacities are those appearing on the aerial load chart attached to the apparatus. DO NOT use any other rating unless approved , in writing, by Simon Ladder Towers, Inc.
1. All capacities are based on outriggers set with extension beams at maximum stroke. The unit’s weight should be removed from the chassis springs, rear tire off the ground, front tires chocked and maintaining contact with the ground.
2. Published capacities are permissible on grades up to 6% (6’ rise within 100’). On grades of 6% up to 14%/3.5 degree up to 8.0 degrees, capacities must be reduced by 50% (one-half). Operating on grades in excess of 14%/9 degrees is prohibited.
3. Certain capacities are limited by structural strength, therefore, tipping cannot be relied on as a load limitation.
4. Capacities are determined for apparatus based on standard unit configuration. The weight of any additional equipment (hose, ladder, axe, etc.) must be deducted from the rated capacity.
CAPACITIES AND LIMITATIONS - continued
WATER TOWER CAPACITIES
DANGER: Operating capacities are governed by the aerial load chart installed on the apparatus. Any deviation from these rated capacities could cause death or serious injury and/or failure of the aerial.
Keep in mind that capacities for water tower operation are in addition to (combined with) those for aerial ladder operation. Therefore, one must be thoroughly familiar with the ladder’s load limitations before attempting any water tower operations. Many of the basic water tower operating rules are based upon reactive force, i.e., the force created at the nozzle (in relation to pressure, flow, and the size and type of the nozzle opening) and transmitted to the aerial structure. This is the same as the force transmitted to the operator when staffing a hand held line. Some of the following items appear on the aerial load chart and are repeated here for informational purposes only.
WARNING: When operating the water tower, refer to Aerial Load Chart for rated capacities and related information. DO NOT RELY ON MEMORY.
1. Water tower/load capacities are established with outriggers fully extended and set turntable level, and the aerial unsupported.
2. Know your capacities. Study this manual and the aerial load chart. Verify all load limitations before initiating any operation.
3. All aerial functions, except swing, may be performed simultaneously with water tower operations. Movement of the nozzle and aerial should be slow and deliberate.
WARNING: Do not swing aerial to position water stream. Rotate monitor to redirect stream.
4. Snow and ice deposits reduce load capacities due to excess weight.
5. A qualified operator must remain at the turntable control console during water tower operations.
CONTROLS AND INDICATORS
GENERAL
The information contained in this section is based on the most common installations. Since control and indicator arrangements are subject to customer specifications, location of specific items in the descriptive text is typical. Your familiarization with the physical configuration of your unit will assist in determining the applicability of the controls and systems covered in this manual.
NOTE: References made to left, right, front, and rear when referring to the aerial are those directions viewed when standing at the heel pin looking toward the ladder tip (ladder bedded).
PRIMARY POWER CONTROLS
Apparatus Battery Switch This unit is equipped with an ignition on/off switch which will make the necessary battery connections.
NOTE: It is important that after the ignition or battery switch has been turned to the OFF position, the switch must be turned back to the ON position until the engine has stopped completely.
Consult the chassis section of this manual for proper start-up and shut-down procedures for this unit.
POWER TAKE OFF (PTO) CONTROL
A PTO control switch is installed in the apparatus cab, in the main control panel. An indicator light on the switch illuminates when the switch is positioned to “on”. Activating the switch energizes a solenoid which allows transmission fluid to the PTO. A clutch within the PTO engages the shaft which transfers power to the hydraulic pump. The truck transmission must be in neutral and the park brake set, before engaging the PTO.
CONTROLS AND INDICATORS - continued
POWER TAKE OFF ENGAGED INDICATOR LIGHT
A pressure switch mounted on the PTO senses pressure inside the PTO and energizes a light adjacent to the PTO switch.
LADDER POWER SWITCH
A lighted power switch is provided in the apparatus cab, on the main control panel. When the switch is positioned “on”, a relay is energized which connects electrical power from the batteries to aerial circuits.
FAST IDLE SWITCH (CAB)
A rocker-type, single throw HI-IDLE switch is installed on the master switch panel in the chassis cab. When actuated, circuitry is completed to provide a preset “fast idle” engine speed (1500 - 1600 RPM’s). Fast idle switches are also located at the aerial control station and at the right rear outrigger control station. These controls are used to maintain higher RPM values for lighting and other auxiliary devices.
HOURMETER
A 12-volt DC hourmeter installed in the apparatus cab, records operating hours with the power take off engaged (which translates to aerial hours of operations).
OUTRIGGER CONTROLS AND INDICATORS
EXTENSION/RETRACTION CONTROLS
Control of the individual outriggers is afforded at the two outrigger control stations at the right and left rear of the truck. The handles provide manual control of the valves which divert hydraulic flow to the required cylinders for deploying the outrigger beam (horizontal) and jack (vertical) cylinders. Pulling up on the handles will raise and retract outrigger jack and beam cylinders. Multiple functions may be achieved by actuating dual functions, but individual outrigger speeds will be reduced. Handles are located to allow the operator to see outrigger movement throughout the entire path of the outrigger travel.
OUTRIGGER EMERGENCY CONTROLS
All rear mount units utilize a manual valve bank for control of the outriggers. Therefore, these units do not have separate emergency/manual controls. This unit is equipped with controls which allow operation of the system if there is an electrical control box malfunction.
OUTRIGGER FULLY DEPLOYED INDICATOR LIGHTS
Working in conjunction with the outrigger interlock system, each outrigger has limit and proximity switches which must be activated before the aerial can be operated. Switches activate when the cylinders are in their full travel position. When all switches are activated for a particular outrigger, its green light at the control box will light. Although the parameters needed to activate the light are met, the operator must set the unit up keeping in mind all the other requirements for the best possible set-up at the fire scene.
OUTRIGGER CIRCUIT PRESSURE GAUGE
A 0 to 5000 psi pressure gauge is piped directly into the outrigger valve bank. The gauge shows selected circuit operating pressure when the outrigger system is activated. The gage is located at the right hand outrigger control station.
INTERLOCK OVERRIDE SWITCH
A covered interlock override switch allows the jack (vertical) cylinder of an outrigger to be lowered to the ground without the beam (horizontal) cylinder being in its fully extended position. This is identified as a “short set” condition which will reduce the safe movement of the aerial.
NOTE: This switch does not limit the unit’s movement to an unsafe area. Aerial movement must be controlled by the operator or the aerial rotation limiting system.
OUTRIGGER CONTROLS AND INDICATORS - continued
MANUAL CIRCUIT SELECTOR
In the event of an electrical failure, the outrigger controls will become disabled because of the interlock system. The circuit selector requires a quarter turn to the left or right for engagement. When activated the manual circuit selector allows hydraulic fluid to the outrigger valve bank which can then be controlled using the standard operating procedures.
MANUAL INTERLOCK OVERRIDE
In the event of an electrical failure, the covered interlock override switch will be inoperable. The manual interlock override is a momentary button which will shift necessary flow of oil to the appropriate outrigger jack for “short setting”.
EMERGENCY POWER UNIT SWITCH (EPU)
A hydraulic failure within the main system will stop normal operation of the outriggers. An emergency power unit with controls at each outrigger control station can be used in conjunction with outrigger function levers and override controls, if necessary, for brief emergency operation of required systems.
AERIAL CONTROL CONSOLE
A control console, dedicated primarily to aerial functions, is installed on the left side of the turntable. Aerial controls and indicators located at the console are described in the following text.
AERIAL FOOT POWER SWITCH
A foot operated aerial power switch is installed on the turntable deck at the control console. The operator must depress and hold the switch in the “ON” position to operate the aerial from the console. Should the operator become immobilized, or leave the assigned station, (foot switch no longer activated), the aerial would immediately become inoperable from the console.
AERIAL CONTROL AND INDICATORS
Aerial function control levers are mechanically linked to the valve spool. Therefore, when the lever is actuated the spool is shifted (moved) proportionally to control lever movement. The travel distance to actuator response, is proportional to control lever movement.
NOTE: Keep in mind that function speed is directly proportional to control lever movement.
ELEVATION CONTROL LEVER
The ELEVATION control lever, located on the right of the swing control, permits rasing and lowering of the aerial when positioned to UP or DOWN.
SWING CONTROL LEVER
The SWING control lever, located between the telescope and elevation controls, permits rotation of the aerial in the desired direction when positioned to LEFT or RIGHT.
TELESCOPE CONTROL LEVER
The TELESCOPE control lever, located to the left of the swing control, affords extension and retraction of the aerial ladder when positioned to IN or OUT. Lever Locations Control levers are located as follows:
|Extend |Swing |Elevate |
|LEFT SIDE |CENTER |RIGHT SIDE |
RUNG ALIGNMENT INDICATOR
An amber RUNG ALIGN (ment) indicator is installed to the left of the aerial controls on the console. The light illuminates when the rungs of all ladder sections are properly aligned for climbing.
AERIAL HYDRAULIC SYSTEM PRESSURE GAUGE
A 0 to 5000 psi, console-mounted gage registers “working” pressure in the aerial hydraulic system. With all controls in neutral (valve spools centered), the gage registers static pressure in the aerial system. When a control lever is actuated, the gauge registers pressure developed to perform that specific function.(Indicated pressure may drop below specified pressure when multiple functions are actuated).
CONTROLS AND INDICATORS - continued
AERIAL ELEVATION INDICATOR
A floating-ball type angle indicator is installed on the left side of the ladder base section at the turntable. The indicator is calibrated from -20 to 80 degrees. Used in conjunction with the load chart and extension meter, the indicator enables the operator to determine the rated capacity at any given length and angle.
FAST IDLE SWITCH
A single throw FAST IDLE switch is installed on the aerial control console and on the right outrigger control station.
MONITOR AND NOZZLE CONTROLS
Three switches located on the right side of the console face allow remote control of the monitor and nozzle. A second control box is mounted on the sliding/retractable monitor mount. Switches are allotted for control of nozzle SWEEP (left and right), ELEVATION (up and down), and PATTERN (fog and stream).
WARNING: When the monitor’s retractable mount is pinned to the mid-section, the monitor must be operated with the controls at the aerial console.
NOTE: Switches at the console will override controls installed on the monitor’s retractable mount.
OUTRIGGER “NOT DEPLOYED” INDICATOR
A red light located at the aerial control station indicates that an outrigger has not been fully deployed, and that a “short-set” condition exists.
OUTRIGGER INTERLOCK OVERRIDE
When it has been necessary to “short-set” an outrigger, the “Not Deployed” indicator will be lit and it will be necessary to use the outrigger interlock override to move the aerial. The override switch has a cover to ensure that its use is deliberate.
WARNING: Improper use of the OUTRIGGER INTERLOCK OVERRIDE SWITCH, or use by an improperly trained operator, could lead to a seriously unsafe situation.
TURNTABLE ALIGNMENT INDICATOR
Two stainless steel arrowheads, one affixed to the turntable deck and one affixed to the body deck, indicate (when aligned) to the operator that the ladder is in the correct position for bedding in the cradle.
WATER FLOW METER
A digital display supplies a continuous read-out of the gallons per minute (GPM) of water being discharged through the aerial’s telescopic waterway and nozzle. This system consists of a sensor in the waterway piping, an electronic module, and the display unit.
COMMUNICATIONS STATION
A two-way communications system consisting of a master station at the turntable control station and a slave station mounted at the tip, allow communication between operators at each station. The station at the tip allows for “hands free” talking and listening.
CONTROLS AND INDICATORS - continued
LOAD ALARM INDICATOR
This alarm system indicates that a preset limit of loading has been reached. The system determines the hydraulic pressure within the lift cylinder circuit. As the load is increased the pressure in the circuit will also increase until the limit is reached, setting off the audible alarm. This system is to be used as a secondary system of warning due to its inaccuracy when the unit is at higher elevations. At higher elevations the load shifts from the lift cylinders to the extension/retraction cylinders and their associated cables. The limitations identified on the load chart for this unit are to be strictly followed to ensure safety for personnel and equipment.
WARNING: Do not load the aerial past the limitations identified on the load chart. Overloading of the aerial can cause equipment failure and death or serious injury to personnel.
DANGER: This unit is not equipped with a rotation limiting system. Movement of the aerial/turntable to positions past parallel to truck or on the same side as a “short-set” outrigger will cause the unit to tip over.
Do not under any conditions move aerial to the prohibited positions.
MANUAL OVERRIDES/EMERGENCY CONTROLS
AERIAL
The QS series units do not have manual override controls as such. The aerial valve bank is located inside the turntable console. The control handles located on the console are manually moving the spool valve spools inside the valve bank, and shifting the hydraulic fluid as the handles are moved.
IN THE EVENT OF AN ELECTRICAL FAILURE, NOTIFY THE SHOP IMMEDIATELY.
In the event of an electrical failure, it would be necessary to actuate the blocking solenoid valve located at the back wall of the turntable weldment, just forward of the turntable step. To actuate the valve, push the knob in and turn slightly to the left. Fluid flow is now possible to the main control valve. Aerial may now be used as absolutely necessary for rescue procedures. Electrical problems must be corrected as soon as possible. When aerial procedure is complete, push and turn solenoid knob to the right to re-engage valve for outrigger operation.
DANGER: With blocking solenoid disengaged, aerial must be used in accordance with limits defined by the outrigger set-up (aerial must not be used on the same side as a “short-set” outrigger).
NOTE: Restore solenoid knob to its original position before outriggers are moved.
Use of the EPU (Emergency Power Unit) will be required if a hydraulic failure has occurred. The momentary switch, located at the outrigger control stations must be held ON to provide fluid flow to aerial systems. Only limited function needed to wrap-up the unit are suggested because of the short continuous use time of the EPU. If both electrical and hydraulic systems have failed, a combination of both procedures above will be needed.
APPARATUS READINESS CHECK
OPERATOR’S DAILY CHECKLIST
The following “checklist” items should be used in conjunction with the walk around inspection diagram during daily, operational readiness checks of the apparatus.

SET-UP PROCEDURES
PRIORITY CONSIDERATIONS FOR SET-UP
Rescue capability is always the primary concern when positioning the apparatus for operation. With proper training and experience gained from previous fire ground operations, such assessment and action will become instinctive in nature. Upon arrival at the fire scene, the following factors must be taken into consideration prior to positioning the aerial ladder apparatus for use:
WARNING: Due to the overall length of the aerial, it is most important to position and setup the apparatus to the best advantage of existing conditions. Avoid any situations which could deteriorate and result in the apparatus tipping, overloading the ladder, subjecting the aerial to contact with charged conductors, or any other known hazardous environment.
1. Required reach and intended use of aerial.
2. Ground conditions and slopes affecting stability.
3. Overhead obstructions and hazards.
4. Conditions favorable to operating “over the rear.” (“Over the rear” operation is defined as angles up to and including 45 degrees to either side of the apparatus centerline. “Over the rear” affords the most stable operating position for the aerial. Greatest reach is also gained with the aerial positioned “over the rear”).
5. Accessibility to onboard equipment.
6. Existing fire, fireground conditions, and those likely to develop.
7. Not obstructing approach or exit, or otherwise interfering with simultaneous fire ground operations.
PREOP REQUIREMENTS
AERIAL OPERATIONS ONLY
1. Position the apparatus in the best possible location, keeping in mind that operating “over the rear” offers maximum capacities and optimum performance.
2. With engine at slow idle (600 rpm approx.) and apparatus transmission in neutral, set the parking brake and chock the front wheels (in front of and behind tires).
3. With engine at slow idle (600 rpm approx.) and transmission in (N) neutral, actuate PTO control switch. This energizes a solenoid, opens a valve, and allows transmission oil pressure to engage a clutch pack integral of the PTO. Check the PTO engage light is illuminated.
4. Actuate the fast idle switch at the outrigger control station, to set engine at the required speed for outrigger operation.
NOTE: Aerial fast idle will not work unless the parking brake is set and the transmission is in neutral.
AERIAL AND WATER TOWER OPERATIONS
NOTE: Units with and without pumps can be used as water towers. Units without pumps will require another unit with a pump to supply water to the rear inlet of the unit. Water can then be pumped through the unit’s water way to the monitor.
NOTE: Electric monitors are functional as long as the ladder power switch, located on the cab’s overhead control panel, is in the “ON” position.
NOTE: Follow procedures as outlined in Preop requirements for aerial operations.
OUTRIGGER OPERATION
DEPLOYING THE OUTRIGGERS
The proper method for deployment of the outrigger system is to relieve the weight from the vehicle’s springs and tires (rear tire not contacting the ground, front tires contacting the ground), allowing the frame and aerial torque box assembly to assume the operating load.
WARNING: When operating on slopes or slippery terrain, keep one set of braking (wheels with air actuated, spring applied brakes) tires firmly on the ground.
NOTE: References made to left, right, front, and rear when referring to the aerial are those directions viewed when standing at the heel pin looking toward the ladder tip.
1. Actuate applicable outrigger beam control(s) to the OUT position and fully extend the beam(s); repeat for remaining outrigger(s) as necessary.
NOTE: In the event that an outrigger beam cannot be fully extended, the vertical jack can be lowered by using the outrigger interlock override switch.
2. Place auxiliary pads in position on ground under jack cylinders
NOTE: Outrigger beams can be extended simultaneously and jacks can be lowered together to save time during set-up.
3. Actuate applicable outrigger jack control(s) to DOWN position and lower jack(s) until weight is removed from the chassis springs; repeat for the remaining side as necessary. The outrigger fully deployed indicator light(s) should illuminate when jacks make positive contact with the ground (supporting surface).
DANGER: An electrocution hazard could exist, and death or serious injury could result from contact with any outrigger, should the apparatus become electrically charged (the outriggers are an extension of the apparatus frame).
WARNING: A moving outrigger can cause serious crushing injury. Do not operate any outrigger unless you or a spotter can see that all personnel are clear of the outrigger’s beam and jack travel path, and contact point.
Outriggers must be set on solid footing. Setting outriggers on uneven or unsure surfaces could cause the apparatus to tip over.
All manual locking pins and auxiliary pads must be properly installed/used when outriggers are deployed.
CAUTION: Allow 1/4 inch minimum clearance above locking pin when inserting through holes in the skirt. Continuous operation with weight on the pins could elongate the holes.
4. Install locking pin in each outrigger skirt.
OUTRIGGER OPERATION - continued
LEVELING THE APPARATUS
DANGER: If the angle of the turntable is between 6 and 14% reduce capabilities through 360 degrees by one-half.
If grade permits, level apparatus as follows:
1. Using applicable outrigger controls, raise low side of the unit slightly above horizontal; lower opposite jack to level unit.
WARNING: Maintain front tire contact with the ground in all sloping and level conditions.
2. If raising low side above horizontal cannot be accomplished due to grade, fully extend jack on that (low) side.
3. Lower opposite side jack to adjust unit as near level as grade will allow, ensuring that outriggers are “loaded” with as much chassis weight as possible, and turntable angle is less than 6 percent from horizontal.
NOTE: With conditions as stated in step 3, no weight reductions are required through 360 degrees of aerial rotation.
4. Install locking pin in each outrigger skirt.
5. Make sure the area below outriggers is clear. Outriggers are properly set when the “FULLY DEPLOYED” light comes on.
6. Return engine rpm to slow idle (disengage fast idle).
STOWING THE OUTRIGGERS
CAUTION: Ensure that locking pins are removed from the outrigger skirts before initiating any stowing operations.
1. Remove and stow outrigger locking pins.
NOTE: The outrigger system is not activated unless the aerial is retracted, lowered, and stowed.
NOTE: If the outrigger interlock switch was used to set the outriggers, it will be required for stowing as well.
2. Actuate applicable outrigger jack control(s) to UP position and raise vertical jack(s) fully. The outrigger deployed light should go out; repeat for remaining outrigger(s) as necessary.
NOTE: Outrigger jacks can be raised simultaneously and beams can be retracted together to expedite withdrawal from the fire scene.
3. Actuate applicable outrigger beam control(s) to IN position and stow outrigger(s); repeat for remaining outrigger(s) as necessary.
4. Retrieve and stow auxiliary outrigger pads.
OUTRIGGER INTERLOCK
The outrigger system is equipped with an interlock feature which interfaces with the aerial controls to prevent the use of the aerial if the outriggers have not been correctly or only partially set up. This system is designed to protect the users from the possibility of tipping the truck over because of improperly positioned outriggers. A properly set outrigger is indicated by a green light at its corresponding control station. Illumination of the light confirms that the outrigger has been fully extended horizontally and vertically, and that the unit’s weight has shifted to the outrigger. If any of these conditions are not met the light will not activate. With all green lights illuminated, electrical power is available for use of the aerial. After the ladder has been taken out of the cradle, any movement of the outrigger will not affect aerial operations.
OUTRIGGER OPERATION - continued
INTERLOCK OVERRIDE/EMERGENCY OPERATION
The outrigger interlock override system is designed to allow use of the aerial in situations where lives are at risk and no other options are available. The system allows the outrigger, on the side opposite of where the aerial is to be used, to be “short set,” or not fully extended in the horizontal direction. By activating the interlock override switch, full horizontal extension of one outrigger is not necessary and aerial functions can be accessed. Each aerial control station contains a red “outrigger not deployed” indicator, which warns that an outrigger has not been fully deployed and that use of the override switch will be necessary for any aerial functions.
WARNING: Use of the aerial while in an override situation must be limited to the area parallel with the truck forward, to parallel with the truck rearward, and on the side opposite of the “not fully deployed” outrigger.
When used properly the system is safe, but additional caution is needed because there is no system to prevent accidental or deliberate misuse by personnel.
DANGER: Utilization of the outrigger interlock override must be used as a last resort, when all other options have been exhausted. Operators must be properly trained and aware of the potential danger if procedures are not followed properly while the system is in the override condition.
The following steps identify correct use of the system:
1. When arriving at the scene, placement of the apparatus must be carefully considered to avoid the need for repositioning the truck.
2. Follow the directions under DEPLOYING THE OUTRIGGERS to attempt a setup.
3. When it is determined that an outrigger cannot be extended fully, it will be necessary to move to object(s) that block full deployment.
4. If the objects cannot be moved, consider repositioning the truck.
NOTE: Experience and knowledge of the unit’s capabilities and limitations should eliminate the need to “short-set” outriggers. This allows the interlock override system to be used in an “EXTREME EMERGENCY” situations for which it was designed.
5. When determination has been made that an outrigger must be “short-set”, extend the outrigger (opposite the side which the aerial will be used) to the farthest point possible.
6. Extend the opposite outrigger’s beam cylinder fully.
7. Place the outrigger shoring pads under the jack cylinder engagement area for each outrigger.
8. Extend the jack cylinders until the weight is relieved from the suspension, while using the apparatus level indicator for proper leveling of the unit.
NOTE: It will be necessary to activate the interlock override switch to lower the short-set outrigger.
9. Install the locking pin in each outrigger skirt.
OUTRIGGER INTERLOCK OVERRIDE
MANUAL CONTROLS
In the event of an electrical failure, the interlock override switch will become inoperative and it will be necessary to use the MANUAL CIRCUIT SELECTOR and the MANUAL INTERLOCK OVERRIDE button to lower the jack cylinder in the “short-set” condition. The procedure is as follows:
1. Interlock override switch and outrigger function controls are identified as inoperative.
2. Push and turn the manual circuit selector control 1/4 turn to the left and release.
3. Push momentary manual interlock override and hold while moving outrigger control handle to lower jack cylinder.
4. Install locking pin in each outrigger skirt.
NOTE: In normal or emergency operation, the possibility of a hydraulic failure is always present. In this situation it is necessary to use the E.P.U.(Emergency Power Unit) Switch to supply hydraulic power in conjunction with the systems previously described.
5. Repeat steps (1) through (4) as necessary.
AERIAL OPERATION
GENERAL SAFETY INSTRUCTIONS
WARNING: An untrained operator subjects himself and others to death or serious injury. Do not attempt to operate the apparatus until you have read, understand, and can apply the safety precautions and operating procedures contained in all applicable manuals and regulations.
Before attempting any aerial operation, review safety precautions, and capabilities and limitations sections of this manual.
Do not operate this unit until you have been fully trained in its safe and proper operation by qualified personnel.
You must operate within the limits of the city of Oklahoma City’s work rules and all applicable government regulations.
Failure to obey any of the following could result in death or serious injury.
1. Inspect vehicles and aerial DAILY, including functional checks of all systems.
2. Outriggers must be set on solid footing to prevent tip-over, manual locking pins must be installed.
3. Operators shall wear body belt and use a lanyard to secure to ladder.
4. Always operate any controls slowly for smooth motion.
5. Do not load aerial beyond rated capacity.
6. Operator should wear proper protective gear.
7. Read and comply with all safety and operating decal on the apparatus.
As a safety precaution, the operator should make note of and report any signs of trouble observed during normal operation. Be alert of the following:
1. Excessive hydraulic pressure.
2. Hydraulic oil leaks.
3. Excessive hydraulic oil consumption.
4. Any unusual noise or vibration.
5. Any erratic movement of ladder or controls.
WARNING: A qualified operator must remain at the turntable control station at all times.
PINNING THE RETRACTABLE MONITOR FOR OPERATION
WARNING: Waterway must be fully drained, ladder fully retracted, and aerial positioned to zero degrees elevation, before changing pinned position of monitor.
NOTE: Since rescue capability remains the primary concern when arriving at the fire scene, it is recommended that the monitor be pinned to the mid-section as a standard configuration. For maximum water tower operations, the monitor is pinned to the fly section.
1. Drain waterway as necessary, and retract and position aerial at zero degrees elevation.
2. Insert locking pin in the appropriate position for selected monitor configuration; refer to placards adjacent to the sliding mount pinning hole location.
AERIAL FUNCTIONS
NOTE: Maximum aerial strength is afforded at the shortest radius, with the ladder at maximum length and highest permissible elevation.
NOTE: The recommended sequence of aerial operation is elevate, rotate, and extend. The reverse sequence holds true for stowing the ladder.
WARNING: If a tipping condition is encountered, retract and/or elevate aerial to return to allowable operating envelope. Never lower or extend ladder, as this will only worsen the condition.
MONITOR AND NOZZLE OPERATION
WARNING: Refer to aerial load chart for maximum horizontal and vertical sweep of nozzle.
CAUTION: Do not hold nozzle against any stop or full travel position in any function, as damage to motor will occur.
NOTE: Controls for nozzle operation are located on the aerial control console at the ladder tip.
When the monitor retractable mount is pinned to the fly-section, the nozzle shall be remotely controlled from the aerial console. Sweep nozzle to reposition stream whenever possible (as opposed to swinging the aerial). Refer to vendor information, supplied with the monitor and nozzle, for additional information.
RAISING AND LOWERING THE NOZZLE
Position RAISE/LOWER control to direction required; hold until nozzle reaches desired position.
ADJUSTING NOZZLE PATTERN
Position STREAM/SHAPE control to pattern required; hold until nozzle reaches desired position.
SWEEPING THE NOZZLE
Position RIGHT/LEFT control to direction required; hold until nozzle reaches desired position.
RAISING/LOWERING THE LADDER
NOTE: The recommended sequence of aerial operation is: (1) ELEVATE, (2) ROTATE, (3) EXTEND. The reverse holds true for bedding the ladder.
RAISING THE LADDER
WARNING: Before raising the ladder, make sure that the area above is clear of overhead obstructions.
Position the ELEVATION control lever to UP; hold until ladder reaches the desired elevation.
NOTE: Engine RPM and control lever distance from neutral determine speed of raising ladder.
LOWERING THE LADDER
WARNING: Before lowering the ladder, make sure that the area below is clear of any obstructions.
Position the ELEVATION control lever to DOWN; hold until ladder reaches the desired elevation.
NOTE: Engine RPM and control lever distance from neutral determine the of lowering ladder.
RAISING/LOWERING THE LADDER - continued
SWINGING THE AERIAL
WARNING: Before swinging the aerial in either direction, ensure that swing path is clear of obstructions and personnel.
Never rapidly reverse swing direction as a sudden change of direction could dislodge personnel on the ladder, turntable, platform and/or damage the swing mechanism.
CAUTION: Ensure that aerial is raised sufficiently to clear cradle, cabinetry, accessories, etc., prior to swinging.
Position SWING control lever to LEFT or RIGHT as required; hold until aerial reaches desired position.
NOTE: To increase swing speed, control handle is moved further away from (N) neutral (center position). To decrease swing speed, control handle is moved closer to (N) neutral (center position).
NOTE: Better “feathering” control of swing movement (when close to operating hazards, i.e., buildings, power lines, etc.) can be attained with engine at “slow idle” RPM.
NOTE: Aerial is equipped with an automatic swing brake. Brake will engage when the control handle is returned to (N) neutral (center position).
EXTENDING/RETRACTING THE LADDER
NOTE: Refer to the markings on the ladder for readout of LADDER EXTENSION (length).
EXTENDING THE LADDER
DANGER: Never extend ladder with personnel onboard, as sufficient power exists to mangle or sever any limb caught between the rungs.
WARNING: Before extending the ladder, ensure that extension path is clear of obstructions and personnel.
Do not rest ladder on structure. The ladder is designed to support rated loads in the unsupported configuration.
Position the TELESCOPE control lever to OUT; hold until the ladder extends to the desired length.
NOTE: Engine RPM and control lever distance from (N) neutral determine the speed of ladder extension.
RETRACTING THE LADDER
DANGER: Never retract the ladder with personnel onboard, sufficient power exists to mangle or sever any limb caught in the rungs.
WARNING: Do not rest the ladder on any structure. The ladder is designed to support rated loads in the unsupported configuration.
Position the TELESCOPE control lever to IN; hold until ladder retracts to the desired length.
NOTE: Engine RPM and control lever distance from (N) neutral determine speed of ladder retraction.
AERIAL OPERATION INTERLOCK OVERRIDE MODE
With the outrigger in a “short-set” condition, the outrigger not deployed lights at the turntable and platform consoles will be illuminated. In order to actuate aerial functions, it will be necessary to hold the interlock override switch in the actuated position throughout the use of the control lever. This is designed to make each movement of the aerial deliberate and thought out. the interlock override switch can be released when aerial movement is complete.
DANGER: Movement of the aerial/turntable to positions past parallel to truck or on the same side as a “short-set” outrigger will cause unit to tip over. Do not under any conditions move the aerial to the prohibited positions.
WARNING: Releasing the interlock override switch while in motion will cause aerial to stop abruptly.
MANUAL OVERRIDE/EMERGENCY PROCEDURE
The QS series units do not have separate manual controls to apply in case of an electrical failure. The control levers for aerial operation act directly on the aerial main control valve. In the event of an electrical failure it will be necessary to activate the blocking solenoid mounted forward of the turntable rear step. A slight push and turn to the left of the control knob will allow hydraulic flow to the aerial valve.
NOTE: Blocking solenoid at the outrigger control station must be in the inactivated or IN position for aerial use (normal position).
Aerial controls can now be used following procedures identified in the non-emergency section. Because there has been a failure within a major system, it is important that necessary functions be completed, and the electrical problem corrected as quickly as possible. When all procedures are complete, it will be necessary to return the blocking solenoid to the normally closed position by pushing and turning the knob slightly to the right, until engaged in the detent. In the event that a hydraulic failure has occurred, it will be necessary to utilize the EPU to supply hydraulic fluid to the valve bank.
NOTE: An additional operator will be necessary to activate the Emergency Power Unit at the outrigger control station.
Both an electrical and hydraulic failure will require the use of the EPU control in conjunction with the previously described procedures.
CHARGING/DRAINING AERIAL WATERWAY
NOTE: Prior to charging the waterway, maneuver aerial into the best position to direct nozzle stream.
1. Charge aerial waterway as follows:
DANGER: Prior to charging waterway, ensure that the nozzle is positioned in a safe and effective direction.
a) Check that the waterway drain valve is closed.
b) Slowly open applicable water supply.
CAUTION: Drain waterway immediately in freezing conditions. Failure to do so will result in damage to the seals of the telescoping sections.
2. Drain aerial waterway as follows:
a) Close applicable water supply.
WARNING: Do not attempt to drain the waterway by retracting the waterway.
b) Slowly open manual aerial drain valve and drain waterway.
NOTE: Waterway will drain easier with the ladder elevated.
FLOW METER
The aerial waterway flow meter, which is mounted in the turntable control console, is used to identify water flow in gallons per minute. Meter allows flow limits, listed on unit load chart, to be identified easily.
OPERATING IN SUBFREEZING CONDITIONS
WARNING: Before operating in freezing and subfreezing environments, ensure that all control cables, linkages, cylinders, handhold, walking surfaces, etc. are free of snow and ice deposits.
Visually inspect swing gear and pinion for any snow and ice accumulations that would restrict operation.
NOTE: If snow or ice is hampering any aerial function, “jog” applicable control to free actuator.
When operating in extreme cold, subzero temperatures, the hydraulic pump should be operated at “slow idle” until the hydraulic oil reaches a minimum of 60 degrees F. This helps to prevent the pressure filter from bypassing cold, thick oil directly into the system, without the benefit of filtration. Warmer oil also reduces the stiffening effect that cold temperatures induces on flexible hoses.
Special attention must be paid to the hydraulic oil in ensuring that it is kept free of water contamination. Emulsified water can freeze out of the hydraulic oil as crystals, in turn blocking the suction line filter and causing pump cavitation (with possible pump damage).
It is also very important to avoid water contamination of hydraulic oil/reserves in subzero operation. Water crystals can block the suction strainer, resulting in damage to the hydraulic pump.
STOWING THE AERIAL
WARNING: Observe all danger, warning, and caution notices applicable to individual operations required for stowing the aerial.
1. Drain the aerial waterway as necessary.
CAUTION: When returning the ladder to the cradle, ensure that sufficient elevation is maintained to clear apparatus cab and attachments. Ensure that the ladder is aligned with the cradle when stowing so that cabinets, lights, etc., are not damaged.
2. Fully retract, rotate. and lower the aerial into the cradle; hold the ELEVATION control in the DOWN position and gently “power” aerial into the cradle. This will aid in preventing aerial bounce during travel.
3. Adjust engine RPM to “slow idle”.
4. Remove and stow outrigger manual lockpins.
5. Return engine RPM to “fast idle”.
6. Raise and stow outriggers; retrieve and stow auxiliary outrigger pads.
7. Adjust engine speed to “slow idle” and disengage PTO.
8. Actuate LADDER POWER Switch to the OFF position.
9. Shift transmission to (N) neutral.
10. Retrieve and stow wheel chocks.
EMERGENCY POWER UNIT OPERATION
EPU OPERATION
The Emergency Power Unit consists of an electric motor and a small hydraulic pump which, when activated, allows the operator to move the aerial or outriggers in the event of a main system failure. The system is capable of all functions in a no-load condition,. However, because of short continuous use limit time, it is important that only required functions be used to move personnel and equipment to safety. Functions should be limited to those associated with wrap-up of the aerial. The outriggers can be stowed, to allow truck movement in a situation of impending danger. The EPU can be used over a long period of time at a 7% duty cycle, which is approximately 21 seconds in 5 minutes.
NOTE: The EPU should be run every 10 hours of aerial use to circulate oil in the system and ensure the unit is working properly.
CAUTION: The EPU is rated for a maximum of three minutes of continuous operation. Exceeding this period of time will cause the unit to fail. Actual operating time is dependant on the batteries state of charge and hydraulic pressure in the circuits being moved.
NOTE: EPU operation is independent of the aerial electrical system.
1. Disengage the main hydraulic pump.
2. Actuate EPU switch to the ON position and hold for duration of the emergency system operation.
3. Operate applicable controls and stow aerial and/or outriggers as necessary.
4. Release EPU switch.
INSTA-CHAIN (THE AUTOMATIC ICECHAIN)
OPERATING INSTRUCTIONS AND RECOMMENDATIONS
ENGAGING THE INSTA-CHAINS
1. The Insta-Chains work best when engaged while moving, and before slippage occurs.
2. The Insta-Chains may be disengaged at any time.
3. When approaching an icy grade and you don’t have the Insta-Chains engaged, slow down to 25 mph and engage the Insta-Chains. Then slowly regain and maintain your speed.
USE OF THE INSTA-CHAINS WHILE THEY ARE ENGAGED
1. The Insta-Chains work better at speeds of more than 5 mph.
2. The Insta-Chains should be engaged between 5 and 25 mph. If you need to engage the Insta-Chains from a stand still, spin the tires 5 mph before engaging the Insta-Chain. This will prevent the Insta-Chains from becoming tangled.
3. Do not exceed 30 mph with the Insta-Chains engaged.
4. When climbing a hill with the Insta-Chains try to maintain your momentum, this will improve the performance of the Insta-Chains.
5. For best results while moving, accelerate slowly, spinning the wheels will result in a loss of traction.
6. While using the Insta-Chains in reverse, the Insta-Chains will work best at speeds above 7-10 mph.
BRAKING AND STOPPING
1. When stopping on snowy or icy roads, engage the chains before stopping to increase traction, and to increase traction when restarting.
2. Avoid locking the brakes while braking under any conditions.
AERIAL MAINTENANCE
ON LADDER TRUCKS FOR ALL 1995 SIMON LTI LADDER TRUCKS
TO BE PERFORMED EVERY 10 HOURS OF LADDER RUN TIME
LADDER GREASING
Utilizing a bucket of “Amsoil” brand grease and 3” paint brush, grease the following:
▪ All black areas inside and outside the ladder sections.
▪ All sheave wheels for extension and retraction cables (zircs).
▪ Top & bottom lift cylinder pin bushings (zircs).
▪ Heel pin bushing (zircs).
Under ladder on top plate of turntable (center), grease fittings to rotek bearing. Note: Ladder needs to be rotated during bearing greasing (2 full rotations while steadily applying grease) (1/4 tube).
BLACK GORE TUBE (PLASTIC)
Spray with a teflon base dry lubricant. Very important to use a type that will not attract dirt, etc. If this happens, lubricant will contaminate with dirt and shorten overall life of the gore tube considerably.
MONITOR
Grease with white lithium or similar where gear drive of motor meets teeth of gears. Apply with brush.
WATER PIPE SLIP TUBES
Saturate tubes with a clean rag with a with automatic transmission fluid with ladder at 0 degree off the side of the truck. Wipe ATF thoroughly over all inner pipe sections (mid & fly) At top end of base and mid pipe, grease fittings until grease relieves form opposite side.
RECOMMEND LADDER SECTIONS AND WATERPIPE SECTIONS BE CLEANED OF ALL OLD GREASE AND DIRT BEFORE APPLYING NEW COAT OF GREASE OR ATF (WATER PIPE SECTIONS)
DO NOT PERFORM THE FOLLOWING
▪ Apply grease or lubricant to ladder cables.
▪ Apply grease or lubricant to outriggers. Occasionally clean outrigger surfaces with a clean dry cloth.
