摘要： A traction hoist of the type in which a rope is wound around a drum to provide a plurality of windings in side by side substantially parallel relationship. The shunting of the rope from one winding to the adjacent winding and the tensioning of the rope is accomplished by rollers so as to minimize power loss, provide automatic self-reeving action and to permit either end of the rope to be the tensioned end. Means is provided for indicating the presence of a damaged rope and for automatically shutting off the power in the event such damage is detected.
