How heavy is the steel rope for lifting I-beam?

How heavy is the steel rope for lifting I-beam?

Answer:

Lifting the I-beam, the steel rope is calculated according to the weight of the hoisting I-beam, and the weight of the wire rope can not be selected without the weight of the lifting at one time.
The main varieties of wire rope are phosphating coating, steel wire rope, galvanized steel wire rope and stainless steel wire rope.
The cause of the failure of wire rope is fretting fatigue, manganese phosphate and zinc manganese phosphating are bonderizing, can improve the wear resistance and corrosion resistance on the surface of the wire, not easy to wear and easy corrosion of the fatigue life is three times of smooth wire rope, the highest test has reached four times, can be verified by the fatigue test, far more than the imported wire rope, the use of lower cost, higher cost, phosphating coating steel wire rope is the patented technology, many enterprises have already authorized for production, for reference only.
