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.

Superiority:

1.Wear resistance.

2.Bending fatigue resistance.

3.Good softness and abrasion resistance

4.We have advanced and fully comprehensive specified lengths service in the wire rope industry.

5.We provide the speified lengths of fiber core service in the whole wire rope manufacturing process.

6.We have advanced and standardized packaging system.

7.We adopt the high quality sisal as the fiber core,and acording to the customer request.

8.Low structural elongation and high bending fatigue resistance performance.

9.The lubrication adopts the good quality grease oil.With the professional greasing process,make the grease coating evenly and the lubrication more uniform.

Safety Notice:

1.In steady speed.

2.Never overload .

3.Inspect regularly.

4.Clean and replace lubricant to wire rope periodically.
