发明名称 Rope or chain hauling pulley
摘要 A pulley is described for hauling strands of rope or chain and for engaging a splice coupling a strand of rope to a strand of chain. A plurality of pockets are arranged about the periphery of the pulley for positively engaging every other chain link. A plurality of pairs of rope-engaging surfaces are located between adjacent pockets and within the pockets. Rope and chain occupy substantially the same diameter of the pulley resulting in substantially the same speed and torque characteristics whether rope or chain is being hauled.
