A winch having a U-shaped frame with a base and a pair of legs extending downwardly from the base. The frame is provided with a transverse, mounting slot extending across the base and into the legs where such terminates at opposed, dog-legged ends. A roller is rotatably secured to the legs. One end of the roller is provided with a number of sockets for engagement with a lever and is reinforced by a collar. A ratchet wheel is affixed to the other end of the roller. A pawl suspended from one of the legs selectively permits the ratchet wheel and attached roller to rotate in one direction.
