Polyethylene Sheaves for Rope-Drawn Transportation System Abstract A sheave for cooperating with a cable is made from ultra-high-molecular-weight polyethylene (UHMWPE). The groove angle is selected according to the coefficient of friction of the UHMWPE so as to prevent the cable from climbing out of the sheave groove. The low coefficient of friction of UHMWPE makes possible a very shallow groove.
