Let the rope does not become the vulnerable parts of Manual Block

Steel wire in Manual Block  is wearing parts, if in the process of using improper use or maintenance is not in place,motorized chain hoist very willing premature can cause rope scrap, so what can delay or maintain the normal use of the steel wire rope? Eagle electric hoist manufacturers to disclose to you.
Firstly, the mechanism of wire rope bending fatigue, then analysis of spiral multi-layer winding drum so that the wire rope is how rolling and wear, illustrates the influence of wire rope diameter tolerance, put forward to the improvement, wire rope hoist suppliers finally to find the solution from the rope itself. Between the steel wire rope in winding rope mutual grinding produced Nick, lead to premature failure of wire rope. Strand wire rope outside more closely, mutual notch less. So we must put the wire rope has 6 edges or 8 edges cross section made of circular cross section in order to solve the problem. The forged display lifting equipments rope round section in bending machine and a multilayer test, the service life can be 2 times.
