( The electric rope hoists type МРМ represent new construction high technological and compact products with high level technical and operating parameters. They are designed for lifting and moving loads on a monorail way.

. Mounted on a double-rail trolley they represent independent modules which are widely used in the modern crane construction.

( The construction of the electric hoist is realized without clutch, with a compact assembly gear box, which makes the product considerably reliable and easy for operating for all the rest.

( The modifications of the electric hoist include a wide scale of variety, depending on the multiplicity of the reeving; stationary or traveling with a trolley; with normal or diminished building height; depending on the type of the suspension – solid or hinged and modification in consideration with the relative climatic conditions: normal, tropic and marine.

(The control of the electric hoist is realized through a relay-contactor system.

The electric hoist are realized with thermo protection of the lifting electric motors and emergency “STOP” button on the control panel and load limiter.

( On request of the customer the following realizations are possible to be made:

- with electronic or mechanical load limiter;

- with timer for counting the working hours;

- with supplying voltage different from 400V (380) and frequency 60Hz;

- with latchkey;

- with digital indication for the load.

The voltage, which is used in the operating chain, is secure. – 24V (42V) and it is obtained by a step-down transformer.

The commanding is realized by a pendant command switch which provides an electrical and mechanical blocking between the buttons for the different travel directions of the lifting and moving devices.

( Operating conditions of the hoist:

- minimal temperature - –25оС (- 400С);

- maximal temperature - +400С;

- relative air humidity – 85( at temperature +25 оС;

- in closed rooms or at open-air under a shed at normal fire hazard

- altitude above sea level up to 1000m;

- for normal, tropical and sea environment за;

- supplying voltage 400V (380V) and frequency 50Hz;

- degree of protection:

Of the electric panel IP54; of the electric motor IP55; of the control panel IP56.

(The electric hoists with trolley can move on a monorail way, made from standard profiles with or without belt inclination in the form of the profile, according to DIN 1025, GOST 19425 and belt length from 130 mm to 300 mm.

The average operating time per 24 hours Tm is determinate by using of the following formula:

[pic]h

Where:

Н – lifting heightвисочина на вдигане;

N – number of cycles per hour;

Т – total operating hours per day;

V – lifting speed.

( Criteria for choosing an electric hoist:

► maximal load;

► lifting height;

► lifting speed – with basic speed, with basic and reduced speed;

► operating duty;

► lifting speed;

► reeving;

► constructive realization – normal/reduced building height.
