The invention discloses a novel combined hoisting method for four crawler cranes, and relates to the technical field of ship and ocean engineering. A novel method for combined hoisting of four crawler cranes comprises the crawler cranes, the four crawler cranes are symmetrically distributed in pairs, steel wire ropes are hung on the two symmetrically-distributed crawler cranes, hoisted structures are hung at the bottoms of the steel wire ropes, supporting rods are hung on the other two symmetrically-distributed crawler cranes through the steel wire ropes, and the hoisting structures are connected with the supporting rods through the steel wire ropes. A steel wire rope is hung at the bottom of the supporting rod, another steel wire rope is hung at the bottom of the steel wire rope through a shackle, and the bottom of the steel wire rope is hung on the top of the hung structure. Through the arrangement of the shackles, the supporting rods and the steel wire ropes, the distance between the lifting lugs on the upper portions of the supporting rods is larger than the distance between the two lifting lugs on the corresponding structure, the lifting radius is reduced, the lifting capacity of the crane is improved, the unfavorable situation that statically indeterminate is likely to happen when the four crawler cranes are combined is avoided, the combined lifting structure of the four crawler cranes is safely completed, and obvious economic benefits are achieved.

    本发明公开了四台履带吊合吊新方法,涉及船舶与海洋工程技术领域。四台履带吊合吊新方法,包括履带吊机,所述履带吊机设置有四台,两两对称分布,其中两台对称分布的履带吊机吊挂有钢丝绳,所述钢丝绳底部吊挂有被吊结构,另外两台对称分布的履带吊机通过钢丝绳吊挂有撑杆,所述撑杆底部也吊挂有钢丝绳,该钢丝绳底部通过卸扣吊挂有另一根钢丝绳,此钢丝绳底部吊挂与被吊结构顶部。本发明通过卸扣、撑杆和钢丝绳的设置,撑杆上部吊耳距离大于对应结构上两个吊耳的距离,减小吊装半径,提高了吊机吊装能力,解决了四台履带吊合吊容易出现超静定的不利情况,让四台履带吊合吊结构安全完成,具有明显的经济效益。
