1. Galvanized steel wire rope can be used as raw material for pressed steel wire rope sling in wet or open environment to enhance rust resistance. 2. In addition to the wear of the outer steel wire, the pressed steel wire rope sling is gradually broken due to metal fatigue caused by repeated bending when bypassing the hook and the hoisted object. Therefore, the ratio of the diameter of the hook or the hoisted object to the pressed steel wire rope is an important factor determining the service life of the pressed steel wire rope sling.
