PURPOSE:To make the loading of a battery and an engine unnecessary and facilitate the equipment inspection and maintenance control of a travel device by providing at a travel frame body supported at a rail, a current collector slide-contacting an electricity feeding conductor and a motor. CONSTITUTION:A travel frame body 5 is in a free travel and movement way supported at a rail 3 through rollers 6, 7 and a motive power transmission mechanism 10, and a current collector 8 and a motor 9 are provided at the travel frame body 5. Also, a spring 14 push-pressing the current collector 8 against an electricity feeding conductor 4, insulating members 15, the current collector 8 and a connecting line 16 connecting the current collector 8 and the motor 9, are provided. Accordingly, the travel frame body 5 can be moved to a destination along a constituent material 2 by sending a signal from the ground, to a receiver 21. As a result, connecting an electric wire whose purpose is for the supply of electric power for the drive of a motor, with the travel frame body, and loading an engine and a battery become unnecessary, and maintenance control, too, becomes easy. |
