<p>PROBLEM TO BE SOLVED: To dispense with assembling and disassembling of respective parts at changing build to reduce labor and improve safety by vertically moving a cargo receiving working platform by driving pinions meshing with racks by a motor, and constituting the cargo receiving working platform of a floor part and a prefabricated scaffolding fixing device. SOLUTION: Racks are fitted on the front face side of supports 1m, 1m on right and left both ends of the carry-in/carry-out port in a prefabricated scaffolding structure through fitting means 4. Next in a cargo receiving working platform 2 suspended with a crane and provided with a floor 2a, after positioning it on the lowermost end side of the racks fitted to the supports 1m, slide mechanisms 2e, 2e on the upper part are built in the longitudinal plates of the racks, and a plurality of rollers are rollably engaged in the form so as to pinchedly hold guide pieces extendingly provided in the vertical direction of the racks from right and left both sides. Hereby mounting of the cargo receiving working platform 2 is completed, and the cargo receiving working platform 2 is moved in the direction of the upper part by driving a motor 2j and rotating the pinions 7 meshing with the racks.</p> |
