Crane Wire Rope, Made of High-toughness Steel Wires

Wire rope is a complex mechanical device that has many moving parts all working in tandem to help support and move an object or load. In the lifting and rigging industries, wire rope is attached to a crane or hoist and fitted with swivels, shackles or hooks to attach to a load and move it in a controlled matter.

Componebts of Wire Rope

There are four basic components that make up the design of a finished wire rope:

• Wires made from metal that form a singular strand
• Multi-wire strands laid around a core in a helical pattern
• A fiber or steel core
• Lubrication

Product Features

• Breaking Strength

Designed for higher breaking strength and better strength to weight ratio, our crane wire rope is made of high-toughness steel wires that have been stretched to their tolerance limit prior to being stranded together to form a rope with optimum spacing between each strand.

Even if wire strands are tightly twisted, there still be spaces in places where the strand touches with each other. To improve the fill factor of the wire rope, we have added irregularly-shaped wire strand to the rope and sent it through rotary swaging process. Steel wires that are laid in a parallel pattern increase the cross section of the rope.

• Safety

Special-purpose steel rope is commonly seen in various engineering projects. Via precision design and rigorous test, the rope usually can meet very high safety standards. A large number of wires are arranged in a parallel pattern to form a strand. Various strands then are twisted to produce the steel rope. Such a rope-making method ensures an improved safety performance of the rope

• Rotation

Our rotation-resistant wire rope contains several strands laid helically around an independent rope core. The lay direction of outer strands is opposite to that of the independent core so that the overall rope can be non-rotating. This series of rope mainly functions as a lifting tool in the crane. It also can be used in a rope take-up system that requires many times of rope winding.

• Bending Fatigue

Increasing the number of strands within a rope and wires in a strand can lead to an extended contact between the rope and the sheave groove or grooved cable drum, thereby reducing the stress acted on average rope. Through adding irregularly-shaped strand to the wire as well as rotary

Swaging process, this contact area will increase to greater extent, as with the decrease of rope stress. Greater flexibility of our steel wire rope means that it can be wound in smaller, tighter circular patterns. When installing the rope onto the drum assembly, its steel and plastic combination design will increase the stability of the whole structure, avoiding internal wire breaking which in turn extends its use life.
