Wire rope is a vital part of the crane operation industry, any one of the mistakes can easily lead to a major accident! Therefore, the hoisting operator must carefully check the wire rope, and those that do not meet the requirements will be scrapped to ensure the smooth operation. There are many ways to inspect wire ropes. Let's take a look at it with Xiaobian.

1.Test method

The wire rope inspector measures its diameter with an oil caliper, and the measurement method is the two outer diameters of the wire rope. Every 100m of the middle section is a measurement point, and two points are measured before and after 1m. Record the minimum diameter, compare with the new wire rope factory measurement diameter, change the measurement point every month, so that monthly fixed, do comparative analysis. The lay distance measurement in the strand of the wire rope is compared with the lay distance measured when the new rope leaves the factory to determine the degree of loose lay.

2. Check components

General position inspection should pay attention to check the wire rope movement and its beginning and end fixed; Pay attention to check the rope section passing through or around the block, especially any part of the rope passing around the block under load; Pay attention to check the rope section of the balance pulley; Pay attention to rope segments that may cause wear on a part of the machine; Pay attention to whether the rope segment has rust, corrosion and fatigue, excessive corrosion of the wire rope should be scrapped in time.
