Xiao Xia Zhang, Chang Sheng Sun, Jian Heng Zhu, Xiao Feng Yang

Abstract

According to the mechanical characteristics of a certain luffing jib tower crane structure, finite element calculation model of the whole machine considering suspended cable under complicated working conditions is built. Nonlinear large displacements static structural analysis of the crane flexible attachment in the on-linear flexible scope is conducted with software ANSYS. The influence of variational attachment parameter on crane structure and anchoring points performance and the flexible attachment rule of crane are researched. Curves of influence of distance between two layers and tower overhanging height on crane structure and anchoring points performance and the reasonable layers and distance of flexible attachment are obtained and attachment rule of flexible attachment tower crane is derived.
