Wire rope is the main force components of the overhead traveling crane, during the operations, if the wire rope pulled off, may lead to serious consequences, resulting in equipment damage, personnel casualties. In order to ensure the safe use of the overhead traveling crane, the wire rope needs to be checked regularly and recorded.
Check the overhead traveling crane wire rope, in addition to visual inspection, can also use the caliper to measure diameter, can also use electromagnetic non-destructive testing to check the internal condition of the wire rope.
When Inspection, first check the wire rope diameter, through the diameter change to determine whether it has not been subjected to a large impact load, etc .;
Then, check the wire rope wear, can use the electromagnetic non-destructive testing LMA to check to determine the wire rope carrying capacity;
Check the number of broken steel wire, in a lay length, the number of broken steel wire reach the scrapped standard, should be updated wire rope;
Finally, the wire rope lubrication, add the oil or grease depend on wire rope condition, antiseptic and rustproof, reduce friction, to extend the wire rope and overhead traveling crane service life.
