Abstract: To guide wire rope as the research object, analyzing the constraint and force of guide rope, get the guide rope stiffness calculation formula. Studied the guide rope lateral stiffness and horizontal displacement along with the change of hoisting height, analysis of guide rope tension and guide rope unit length quality to guide the influence of the stiffness. The results show that the guide wire rope on both ends of the lateral stiffness is very big, the closer the guide rope middle position stiffness is smaller; Guide rope is inversely proportional to the lateral displacement and lateral stiffness, the greater the stiffness, the smaller displacement; Guide rope stiffness with the guide rope tension and guide rope and increases linearly with the increasing of weight per unit length. Reasonable selection guide rope tension, increase guide rope rigidity, to reduce the guide and promote container swing plays an important role.
