55LS2SMA

The 55LS2SMA double-drum scraper winch with a coaxial arrangement of a 55 kW electric motor is designed to deliver rock mass separate from the massif during underground mining. Winches are also used in open cast mining and are a means of mechanizing the storage of bulk and lump materials. Winches are sometimes used to move trains and floating equipment.

The 55LS2SMA double-drum scraper winch with a coaxial arrangement of a 55 kW electric motor is designed to deliver rock mass separate from the massif during underground mining. Winches are also used in open cast mining and are a means of mechanizing the storage of bulk and lump materials. Winches are sometimes used to move trains and floating equipment. The reciprocating movement of the scraper is carried out when the working and idle drum is turned on and off with the hand brake of planetary gears. To enable the working drum, it is necessary to apply the appropriate brake when the engine is running, while the rope is wrapped around the working drum, which causes the loaded scraper to move. At the same time, the rope is unwound from the idle drum. The scraper moves by alternately activating the brakes of the planetary gears of the working and idle drums in the desired direction. Manual winch control. The electrical equipment of winches designed for hazardous gas and dust mines is executed in explosion-proof design. Scraper winches with rope and scraper are not equipped. The main characteristics of the winch are given in the table.
