Abstract
An elevator drive sheave includes a groove in its peripheral surface. A plurality of circumferentially spaced projected teeth are provided in the groove and a lining extends over these teeth. A stranded elevator rope is received in the groove in contact with the lining. The spacing of the teeth is a multiple of the pitch of the strands of the rope. In case of abnormal lining wear, the rope comes in contact with the teeth to insure continued safe tractive force.
