ABSTRACT:
An elevator in which the sheave diameter is reduced and the attendant lowering of the rope life and strength is suppressed to secure safety and reliability. To this end, a rope is used in which a plurality of element wires constituting the wire rope are each covered with resin material and the whole wire rope is covered with resin material, thereby reducing the wear due to slippage between the element wires and the wear due to contact with the sheave, which wear occurs when the rope is entrained around the sheave. When the elevator sheave diameter is reduced, a worried lowering of the rope life can be suppressed or the rope life can be improved. Thus, it is possible to achieve reduction of size and weight of equipment including motors and hoists, installation space saving for elevators, improved safety and reliability of the system by virtue of the increased rope life.
