FIELD: mechanical engineering; load lifting and traction devices. ^ SUBSTANCE: proposed device consists of two drums, traction and winding ones. Traction drum 3 is used to provide constant traction force, and winding drum 6 is used for winding cable 1. Winding drum is connected with traction drum 3 through device 7 coordinating angular velocities of traction and winding drums. Device 7 contains step-up gearbox and self-controlled friction member with adjustable slip moment. ^ EFFECT: reduced power consumption, provision of movement of loads at constant linear velocity. ^ 2 dwg |
