Electric scraper winches SW
Are designed to deliver loosened mined rock of underground development of natural resources, they are also used at open-cut mining and are means of storage mechanization of bulk and lump materials. To-and-fro motion of a scraper is carried out by switching on and off the working and idler drum by handbrake of planetary reducers.
To activate the working drum it is necessary to tight the corresponding brake with operating engine, thus the rope winds on the working drum, that causes the movement of loaded scraper. At the same time a rope feeds off from an idle drum. The scraper moves by means of variable turning on of the brake of working and idle drums’ planetary reducers in the right direction.
Scraper winch are divided into:
- double-drum;
- triple-drum;
- with parallel positioning of the engine;
- with a coaxial positioning of the engine.
