Background
The main operation mode of the large-scale hoisting engineering mechanical equipment is to lift a heavy object to a certain in-place height from the ground, but along with the continuous change of a hoisting construction method, the operation mode of detaching the heavy object from a high place to the ground or hoisting the heavy object from the ground to the underground is also continuously raised, and particularly, the operation mode mostly occurs in the situations of maintenance and equipment well descending operation. However, the operation mode is a great test for a hoisting mechanism of the equipment, and particularly, the problem that the steel wire rope of the LeBus winding drum which is most commonly used at present sinks is always generated.
The most common multi-layer winding LeBus double-fold line winding drum structure well solves the problem of short service life of the multi-layer winding steel wire rope. But the steel wire rope needs to be pre-tightened on the winding drum, the tighter the steel wire rope is pulled, the better the winding is, and the recommended value of the pre-tightening force is generally 2% of the breaking load of the steel wire rope or 10% of the operating load. However, in the actual operation process, the pre-tightening condition is not met more often, especially, the multi-rate is high, the required total pre-tightening force is very large, and the pre-tightening can be only achieved through the lifting hook and the lifting rigging of the construction site.
