The invention discloses a lorry-mounted crane, and belongs to the field of lorry-mounted cranes. A base is designed by adopting a low and flat structure; a positioning mechanism of an amplitude variation movable arm is arranged right below the amplitude variation movable arm; a telescopic oil cylinder is arranged in a telescopic arm, so that the height of the whole crane is lowered effectively, and the stability of the whole crane is improved; a height warning label and an angle indicator are arranged at two sides of the amplitude variation movable arm, and provide reference and help for operators. The adopted technical scheme is that the lorry-mounted crane comprises the base, the amplitude variation movable arm and a lifting arm; the rear end of the amplitude variation movable arm is hinged with the base; the front end of the amplitude variation movable arm is connected with the lifting arm; the base comprises a slewing mechanism and a support frame; the upper end of the support frame is hinged with the amplitude variation movable arm; the lower end of the support frame is connected with the slewing mechanism. The technical scheme can be widely applied to the field of lorry-mounted cranes.
