Elevator Steel Wire Rope

Elevator Steel Wire Rope

Description：

Elevator Wire ropes apply to construct lifting systems and lifts. They are generally supplied as a pair. Right-hand regular lay ropes are generally used in elevator industry. In some special cases, right-hand Lang lay ropes are chosen. The core of elevator wire rope can divide into three types: fiber core, steel core, mixed core. And an elevator wire rope is composed of six, eight or nine strands. A variety of materials can adapt to various needs in life. Elevator steel wire rope equipped with durable, various, reliable safety, bending fatigue resistance.
