The vibration of a crane structure, when a load on the ground is hoisted, is the dynamic response of the space structure to the hoisting excitation. It is a composition of all natural modes. The degree of structural response depends on the hoisting speed, the elasticity distribution and the mass distribution of the crane structure-wire rope-load system, and the state of operation.
