Choosing The Right Wire Rope For Your Crane

To properly operate a mobile crane, having the right wire ropes is not the only thing that maters, but still, it plays a crucial role. But to choose the right wire ropes, you need to have the right kind of knowledge and at least a little bit of crane experience. Knowing which wire ropes are the right ones for you means you understand several types of wire ropes and their best use. In addition of this article, you will find very important information to help you choose easier and wiser.

Every application is most suitable to one type of wire ropes, but how to find out which one will work best for you?
Wire ropes have specific characteristics that provide specific performance abilities.
So, to choose best, you need to closely look at the characteristics of the wire ropes.
Here are the most common characteristics that needto be considered when choosing a rope for your mobile crane.

Strength

The strength of wire ropes is most commonly measure in metric tons and it is shown as minimum breaking force. It means that if a mobile crane with a wire rope is placed under tension, the wire rope should break at the equal or higher number of the calculated breaking force of that rope. The calculated breaking force applies for a new and unused wire rope, so that it should never operate at near or at minimum breaking force. During an efficient life of the wire rope, it certainly loses some strength gradually, because of the natural causes.

Fatigue Resistance

Wire ropes that are capable of repeatedly bending under tension are considered as high-fatigue resistant. To increase the resistance of fatigue, the design of wire ropes should include more wires, both rope construction and wire properties. This means that a wire rope made of more wires will be more fatigue resistant than a rope of same size with fewer wires. Additionally, the wire ropes should never bend over sheaves with a small diameter , because it might lead to excessive bending of the wires.

Rotation Resistance

A torque is created once a load is placed on a wire rope. It is normal, because all wire ropes are designed to operate with a load-induced torque. But the torque may cause both single and multiple part hoisting systems to rotate. So, the load-induced torque can be reduced by using a specifically designed wire ropes. Those specific wire ropes add the torque in same direction and use it to minimize the total rope torque.
