Column Jib Crane Based on ANSYS Analysis of Static Stiffness and Improving Measures

Static stiffness of fixed column jib crane directly affected operating and safety performance. Using ANSYS software for finite element analysis with the consideration of the combined effects of spiral arm and column and the whole structure, the integrated finite element analysis model was established for the whole jib crane and arm-side deflection formula for this type of crane structure was derived. Results verified the deflection formula and the reasonable camber design for spiral arm. Based on the verification, it is aimed to enhance the degree of static stiffness of crane, to improve its response to static stiffness of bend arm to set appropriate degree. In particular, arm deflection ensures correct calculation of static stiffness of the crane foundation, but also on the right arm to set an important basis for degree bend.
