PURPOSE:To ensure a light wt. travelling body, by disposing a track for travelling to an upper portion of an adsorptive surface, by mounting a supporting body to the track in a travelling-free shape and by hanging the travelling body with an adsorptive means through a hanging medium from the supporting body. CONSTITUTION:A track for travelling 3 is disposed to an adsorptive wall surface 1 in a ferromagnetic material as shipping through a hanging and stopping portion material 2 in a mounting and demounting-free shape, and a supporting body 5 is placed on the track 3 in a motion-free form through rollers 6. A taking-up motion 7 driven by means of a motor 9 is installed to the supporting body 5 and a rope 8 is hung. A travelling body 10 is suspended to the rope 8 through a hanging ring 11. Wheels 12 are mounted to the travelling body 10 in a form that the wheels can roll and turn on the adsorptive wall surface 1 while an electromagnet 13 is installed so that adsorbing force work to the adsorptive wall surface 1. Thus, the simplification and light wt. of the travelling body 10 can be attained because the travelling body 10 is suspended by means of the supporting body 5. |
