description The utility model provides a cantilever beam device of a hydraulic lifting trolley, relates to the technical field of lifting trolleys, and aims to solve the problem that the structure at the outer end of a cantilever beam is damaged due to the fact that the structure at the outer end of the cantilever beam is easy to touch the inner wall of a tunnel in the moving process of the trolley when the current trolley is moved after being used in the tunnel. The tunnel trolley comprises a bottom supporting rod, a bottom supporting rod and a bottom supporting rod, the number of the bottom supporting rods is two, and three portal frames are evenly and fixedly installed between the upper end faces of the two bottom supporting rods. Through cooperation of the first outrigger mechanism and the second outrigger mechanism, the trolley can retract by controlling a telescopic rod of a first electric cylinder and a telescopic rod of a second electric cylinder before moving in a tunnel, and the phenomenon that structures at th
