Winch commissioning: winch installation inspection and adjustment after confirmation can supply lubricating parts lubrication mining machinery winch, no-load test run, carried out after the winding-load operation, and gradually loaded to the rated load. In the standard voltage mining machinery winch, the current does not exceed the rating of mining machinery winch much money, motors, and other parts are not fever reducer. Mine shaft sinking winch Safety: winch all exposed rotating parts (except for the drum brake outside) should shield. Roll up the edge of the outermost layer of wire rope height of at least 2.5 times the rope diameter. Winch should set the total stop switch to prevent the risk of emergencies caused.
