Transverse moving trolley

The invention relates to a transverse moving trolley which comprises a lengthwise trolley body, a transverse moving wheel set arranged at the bottom of the trolley body and a driving device for driving the transverse moving wheel set to operate, a longitudinal moving rail is arranged at the top of the trolley body, the longitudinal moving rail is flush with a butt joint rail, and the rotating axisof the transverse moving wheel set is parallel to the lengthwise axis of the trolley body. The transverse moving wheel set is arranged, the longitudinal moving rail is arranged at the top of the trolley body, and the longitudinal moving rail is flush with the butt joint rail, so that it is guaranteed that after a beam body longitudinally moves to the transverse moving trolley, the transverse moving of the beam body is achieved, and after the trolley moves in place, due to the fact that the longitudinal moving rail is flush with the butt joint rail, the beam body can longitudinally move; and therefore, the transverse
