Beschreibung
Zusammenfassung:	The invention relates to the technical field of switch cabinet maintenance, in particular to a switch cabinet transfer trolley which comprises a shear fork type lifting structure, a mounting frame, a hydraulic mechanism, a hydraulic spring and a control system.The shear fork type lifting structure comprises two supporting frames and a base, and the two supporting frames are arranged between the base and the mounting frame in a sliding mode; a connecting pipe is arranged between the two supporting frames, the driving end of the hydraulic mechanism is connected to the connecting pipe, the hydraulic spring is arranged between the hydraulic mechanism and the base, and the control system is electrically connected with the hydraulic mechanism. The lifting structure is used for overcoming the defect that in the prior art, a lifting structure of a transfer trolley is prone to mistaken pressure relief, the device structure can be effectively optimized, lifting stability is improved, mistaken pressure relief is avoided
