摘要：
A bull wheel is disclosed for applying a tensioning or retarding force to cable. The bull wheel has a center drum having a peripheral rim. A series of groove defining segments of resilient material are detachably secured to the rim to form the traction wheel for convenient assembly and repair. In one embodiment the segments are curved and define a single groove. In another embodiment the segments are flat and define multiple grooves and are wrapped at assembly to conform to the curvature of the bull wheel rim.
