Winding machines

Auxiliary winding machine AWM25

It is intended for lowering and rising of the equipment and materials on inclined planes to 30° of coal mines of any category. The mechanical brake works automatically at an engine shutdown. The mechanical brake has the blocking with use of a push-button post of controls KU-91 which does not allow turning on of the engine of the winding machine until the drum is free from influence of a brake belt by means of electric and hydraulic pusher. Turning on of the winding machine “forward” or “backwards” and its stop are made by means of a three-push-button post of controls KU-93 mounted on a barrier, and smooth start-up, stop and regulation of speed — by means of handles of emergency brakes of a drum and a friction clutch. Feature of design is automatic locking of a brake at power cutoff, and also availability of the friction clutch allowing to regulate smoothly speed. The winding machine is characterized by a big towing force, high speed and rope capacity at rather small drive power.

Auxiliary winding machine AWM45

It is intended for handling of the equipment and materials on inclined planes (to 30°) of the coal mines dangerous on gas and dust contents. Adjustment of speed and smooth start-up is provided.

The winding machine consists of a drum with a reducer, two emergency brakes (brake and friction clutch) and a mechanical brake, mounted on the general frame. The design allows regulating drum rotational speed by means of a friction clutch on planetary gear carrier and the emergency brake on a drum.
