Research on New Lifting Technology of Gantry Crane

Abstract

In order to improve the safety, efficiency and economy of hoisting operation for gantry crane, the overall lifting scheme of hydraulic lifting device of double upright door frame cluster with multiple anchors is optimized in the process of hoisting operation. According to the ‘carrying method’ ascension process principle, the innovative design for the hinge structure of gantry crane is conducted. The allowable stress method and limit state design method are applied to make the design and checking calculation of the bearing capacity of crossbeam structure caused by installed load, hinge structure and strength of weld and pin to make sure the safety of hoisting hinge structure. The proposed lifting scheme is more secure, efficient and economic and it has extensive application value.
