The rail 8 is guided into different rail falling positions by the guide device 10 installed on the vehicle frame 12. The electrical and braking control system 6 is installed on the vehicle frame 12 to control the whole vehicle construction and walking. The hook buffer device 1 is installed at both ends of the vehicle frame 12 to be connected to other vehicles. ​​
