Safety device for a cable hoist
U.S. Patent Number: 6131703
Abstract: A safety device for a platform cable hoist within a latticework tower including a plurality of skid members which are flexed inwardly when there is tension from a lift cable. Brake members are secured to the skid members and, in the event the cable fails, the skid members deflect outwardly so that the brake members, which have hook portions at their upper ends, engage transverse braces of the tower. Between the hook portions and the skid members, the brake members are formed with an energy absorbing portion which absorbs kinetic energy from the falling platform to slow and stop its descent.
