When the large all-terrain crane operated under ultra-high hoisting height, the stability of boom system became the key factor of the lifting capacity. The installation of eccentric structure and super-lift device could help to improve the stability of boom system. In order to achieve the best effect of growth, it was important to study the relationship between eccentric structure and super-lift device. The eigenvalue buckling analysis and geometric nonlinear buckling analysis were carried out by ANSYS for the combined boom system of 500 t all-terrain crane with tower jib when lifting load, dead weight, offset load, wind load and lifting rope force were considered. And then the influence rule of the combined relationship between the strut length, opening angle, amplitude variation angle of the eccentric structure and the strut length, opening angle, amplitude variation angle of the super-lift device on the overall stability of combined boom system was analyzed to obtain the optimum parameter combination of eccentric structure and super-lift device, which provides reference for engineering practice.
