The invention discloses a stacking RGV. The stacking RGV comprises a traveling device and a lifting device. The traveling device comprises a vehicle frame, two wheel sets and a drive motor, the wheel sets are fixed to the front end and the rear end of the vehicle frame in the traveling direction of the RGV correspondingly, and the drive motor drives one of the wheel sets. The lifting device comprises a lifting base, two guide columns, a lifting motor and a synchronous belt, the guide columns are arranged in the positions, in front of and back of the lifting base, of the vehicle frame, the lifting base is arranged in the position, between the two guide columns, of the vehicle frame, and the lifting motor is fixed to the vehicle frame and drives the lifting base to ascend or descend through the synchronous belt. The stacking RGV has the advantages that by the adoption of the synchronous belt, the lifting base can be accurately lifted to the accurate height, and a fork carries goods advantageously; meanwhile, the motor driving is utilized, the space temporarily used by the whole mechanism is effectively reduced, and the stacking RGV can operate in a narrower space advantageously; and besides, by the adoption of the design of the front and rear guide columns, the balance of the lifting base during lifting is ensured, and the left and the right portions can be used as a goods entrance and a goods exit correspondingly.
