PURPOSE: To allow a folded plate roof grinding/polishing/cleaning device to be moved safely, easily and rapidly into adjacent wave grooves by providing moving support bases on both lateral sides with supporting arms at the front and rear of the moving support bases, in the positions corresponding to bent pitches plural times of a folded plate. CONSTITUTION: Triangular fitting wheels 33 fitted to the tip parts of supporting arms 20 provided at the front and rear of moving support bases 12, 13 and fitted respectively in the phase adjusted state are placed at the wave crest parts 25 of a folded plate roof 11. In this state, a direction changing and traversing gear 10 for a folded plate roof grinding/polishing/cleaning device 54 is set onto the folded plate roof 1. In this state, a speed reducing motor 49 is rotated to lift the direction changing and traversing gear 10 around the fitting wheels 33 as /fulcrums to take out the folded plate roof grinding/polishing/cleaning device 54 from wave grooves 63. The supporting arms 20 are then rotated to move the moving support bases 12, 13 laterally so as to fit the folded plate roof grinding/polishing/cleaning device 54 into the adjacent wave grooves 63 to terminate lateral movement. |
