The invention relates to an SF6 gas bottle transport vehicle. The SF6 gas bottle transport vehicle comprises a horizontal chassis and a vertical vehicle frame connected to the rear end of the chassis. Auxiliary rolling wheels are mounted at the bottom of the chassis. A main rolling wheel is mounted at the bottom of the vertical vehicle frame. A crawler driven by a motor is mounted at the rear portion of the vertical vehicle frame. The bottom end of a crawler frame is hinged to the bottom end of the vertical vehicle frame. A supporting frame is hinged to the vertical vehicle frame. The free end of the supporting frame is slidably connected to the crawler frame. An angle locating mechanism is arranged between the supporting frame and the crawler frame. The top end of the vertical vehicle frame is connected with an extending-and-contracting handle. A bottle body fixing device is mounted at the front portion of the vertical vehicle frame. By the adoption of the SF6 gas bottle transport vehicle, the up-down stair carrying work of SF6 gas bottles can be achieved conveniently. The SF6 gas bottle transport vehicle is simple in overall structure, stable and reliable to operate and high in working efficiency, and time and labor are saved in operation.
