Torque models are established for wire ropes of different structural characteristics, based on which a torque formula is proposed and used to calculate the torque of the wire rope of a specific structure. According to the calculation results, a general solution of wire rope torsion coefficient is fitted out. Moreover, the effect of wire rope structure and lay angle on the torsion coefficient and the effect of the torsion coefficient on the safety clearance between hoisting containers are analyzed. Finally, opinions are put forward on the production and selection of wire ropes for reference and discussion by relevant practitioners.
