Lifting Wire rope is a vital load-bearing and traction component in lifting machinery. Its main function is to lift, pull, tighten and carry heavy objects.
Drawn galvanized standard wire rope (non-rotation resistant with round wires) is used in many applications as a cargo runner, hoisting, luffing, mooring, towing, and anchoring. It is also suitable for the fabrication of steel wire rope slings for lifting operations. The independent wire rope core (IWRC) provides superior strength and stability compared to fibre cores while maintaining excellent flexibility.
A wire rope must be scrapped if it meets any of these conditions:
1. Use original design models, diameters, and nominal tensile strength. Lower specifications will affect service life.
2. Only use certified wire ropes. If diameter varies slightly, total breaking force must match original design (tolerance < 1.5mm).
3. Prevent knots during winding; knotted ropes are prone to premature failure. Never connect two ropes in a single lifting mechanism.
