LIFTING DEVICE OF PREFABRICATED SCAFFOLD AND ASSEMBLING AND DISASSEMBLING WORK THEREOF

PURPOSE: To dispense with works at a high level as prefabricated scaffolds can be assembled and disassembled only on the ground and hence increase the safety because there is no danger such as falling of workers or dropping of scaffold materials and also operate with ease because of works free from life-lines and further, increase the working efficiency since the working space is not restricted and much area thereof is not required and dispense with cranes. CONSTITUTION: A lifting device in which a lifting girder 9 having detachable claws 20 at prefabricated scaffolds is equipped between masts 8 erected on the ground, is used. The prefabricated scaffold is hooked and hoisted by the lifting girder 9. A lower scaffold is assembled in the lower side. The same processes are repeated to assemble a multi-layer scaffold in turn. The periphery of the second layer from the lowermost one, in the multi-layer scaffold assembled by the lifting girder 9, is surrounded and the prefabricated scaffold is hooked and hoisted as the whole. Then the lowermost scaffold layer suspended afloat is disassembled and removed. The same processes are repeated thereafter to disassemble and remove the lowermost scaffold layer in turn.
