Crane transition assisting device, transport trailer with assisting device and crane disassembling/assembling method by use of assisting device

摘要

A crane transition assisting device, a transport trailer with the assisting device and a crane disassembling/assembling method by use of the assisting device are disclosed. The crane transition assisting device comprises a bearing frame (130) and supporting legs (110) which are mounted on the bearing frame and are equipped with a hydraulic cylinder (111) telescoping in a vertical direction. The bearing frame (130) is provided with at least two suspension arm brackets (120) arranged along the longitudinal direction of a horizontal plane and used for supporting a suspension arm. The assisting device realizes separation or combination of the suspension arm and a rotary table without an assistant lifting mechanism while disassembling/assembling a large-tonnage wheel crane so as to conveniently realize disassembling/assembling a large-tonnage wheel crane. The transport trailer with the assisting device can provides convenience for carrying a suspension arm, and the crane disassembling/assembling method by use of the assisting device can provides convenience for large-tonnage wheel crane transition.
