Crane is a very useful lifting equipment, has a wide range of use, can lift and load heavy objects. But the problem is that during use, the two steel wire ropes of the crane are easy to "kink" and affect the work. Don't worry, the following editor will analyze the reasons and solutions for the knotting of the wire rope for you, hoping to help you.
Some cranes are very tall. The crane accessory wire rope is overloaded during use. Then, the rotating stress of the wire rope gradually accumulates, and when a certain strength is reached, the wire rope will rotate and change. The upper end of the steel wire rope wraps around the drum, and the upper part rotates to drive the lower hook to rotate in the air, so that multiple steel wire ropes surround each other. Therefore, the wire rope is knotted and disordered, which is also called "twisting".
In order to avoid knotting of the wire rope, the fundamental solution is to modify the crane plan. In other words, depending on the diameter of the wire rope, the drum will have more left-hand or right-hand rope grooves. Ensure that the wire rope is aligned along the groove, reducing the possibility of wire rope wrapping. In addition, multi-layer anti-rotation wire ropes should be used. The simple way to solve the knotting problem of crane accessories is to reduce the load, thereby reducing the rotation of the wire rope during unloading. When lifting, keep lifting vertically. Another direct method is to reduce the length of the wire rope under the condition of satisfying the height increase, and effectively reduce the stress accumulation of the wire rope. If the wire rope crane is "kinked", it will not work properly. It is necessary to remove the wire rope from the drum, level it, and then wrap it around the drum. But the cost is high and the operation is inconvenient. This method is not recommended.
