Abstract Hydraulic Tie-Down For Elevators A compensating rope sheave tie-down uses a hydraulic control system comprising various valves to control sheave motion. The sheave is permitted by the control system to move up and down slightly at slow rates, but is held in place if a high rate occurs. The control also permits the sheave to drop down to apply tension to the compensating rope.
