PURPOSE: To easily and safely perform inspection, by allowing a self-running truck equipped with a flaw detecting apparatus to run on a guide track attachable to a structure in a freely detachable manner through an electromagnet.
CONSTITUTION: In the flaw detecting apparatus of the firing furnace wall of the boiler of a steam power plant, a guide track 2 is hung down in a state connected to cables cooperated with the winch mechanism above the boiler and a self- running truck 3 run by a drive mechanism is supported by the guide track 2 while the guide track 2 can further move vertically on the firing furnace wall surface 4 by the cables 1. An electromagnet 5 is mounted to the quide truck 2 in opposed relation to the firing furnace wall surface 4 and said truck 2 is made attractable and fixable to the firing furnace wall surface 4 while a guide wheel 6 is mounted to said track 2 for the sake of vertical movement. On the other hand, the self-running truck 3 is equipped with the flaw detecting apparatus and remote inspection is performed by a remote control apparatus 10. By this apparatus, various kinds of machineries can be accurately conveyed to a desired position and safety is also high.
