Choose the most suitable wire rope for your applications


Do not feel that it is omnipotent because it is called wire rope. In fact, if the type is not chosen, it may be more secure on some occasions. For example, the load capacity of ropes of different diameters is very different from different weaving methods. Generally speaking, after selecting the ropes, it is not allowed to increase the weight of hoisting.

Similar to the ordinary steel, when the load exceeds the load-bearing capacity, the wire rope will appear obvious or not obvious deformation. Generally speaking, coarse ropes are less susceptible to deformation than finer ones. However, if the rough ropes are not subjected to special treatment, they may break. This is why the rope is not thicker and better.

Choosing what diameter of rope is usually in the early stages of construction, experts will give a plan. In the project, it is strictly forbidden to go against the aggravation of the program. You should know that the safety hazard of the hoist itself is very large. Once it breaks, it may cause serious or even serious accidents.
