The main hoist wire rope of a harbor mobile crane is the "lifeline" of the entire equipment, specifically responsible for the vertical lifting of the spreader and containers, making it one of the most crucial load-bearing components of the whole machine.
It typically uses multi-strand twisted wire ropes, such as 6×29Fi+IWR or 6×26WS+IWR, which are flexible and resistant to twisting, effectively handling multiple layers of winding on the drum and frequent lifting impacts. The rope grooves are designed with soft liners and strict dimensional proportions to minimize wire bending and extend service life.
