To improve work efficiency and safety in welding, cutting and the like of a wall or an inclined surface of a steel structure such as a hull, a bridge and a tank by using a horizontal detector provided on a work truck and automatically controlling the travelling direction of the truck based on the horizontal plane as a reference.
On the inner center of a truck body 1, a permanent magnet is arranged that moves vertically against the bottom of the truck by a handle 5 operation, making the truck body 1 adherable to an object to be worked. A controller is also provided in the truck body 1, controlling the start, stop and distance of travelling as well as the beginning and end of an operation for the truck A, imparting independent driving to the motor for the left and right wheels of the truck A, and making the travelling direction controllable. At the time of an operation, the angle dial 3a of the horizontal detector is set at a prescribed angle, making the truck run with the travelling direction automatically controlled. During the travelling, the signal of the horizontal detector is inputted in a comparative arithmetic part; in the case where the angle dial 3a is inclined against the horizontal surface, a signal is transmitted to the controller, controlling the wheel driving motor and steering in a required direction left and right.
