Abstract: An improved cable hoist apparatus has a sheave movably connected relative to a frame to bias the cable in a circumferential groove in the sheave. A biasing means on the frame compresses the cable in the sheave groove with the amount of force depending upon the tension in the cable. In this regard, the sheave is positioned relative to the frame as a function of the cable tension such that the greater the cable tension, the greater the biasing force on the cable. However, the biasing means can include a plurality of rollers to regulate the biasing force. A reeving spring can be used in conjunction with the biasing means to allow reeving of the hoist when the cable is unloaded. The hoist apparatus optimally incorporates certain advantageous safety features. These include a cable brake activated and released depending upon the position of the sheave and a motor shutoff as a function of overload and/or underload.
