The construction site, hoist rope on the ropes around the tube system disorder often occur, then squeeze each other rope, wear serious, shorten the life of the wire rope; Meanwhile, the windlass wearing spacing devices-generally heavy hammer or screw. Mallets-installation maintenance inconvenience, screw-type arrangement as rope around disorder caused spacing failure. In order to overcome the above drawbacks, the hoist to attach a rope agencies. Pai brought the design to reduce speed gear boxes for the moment, the drive to make arrangements justice agencies reciprocating linear motion. can make rope winch drum, were neatly arranged. Use the bodies uniform rope so as to enhance the life of the wire rope, thereby increasing production efficiency, reduce labor intensity.
