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.
