<p>PURPOSE:To realize an appropriate time required to lift a long-sized article and execute the smoothing of construction work even when the building under construction becomes higher by providing a plurality of vertical conveyor devices which are mounted on the external wall surface of the building under construction in a mutually separated manner and a platform part where a part of the long-sized articles to be lifted can be loaded. CONSTITUTION:A plurality of vertical conveyor devices 4 are mounted on the external wall 1 of a building under construction according to the length of the long-sized articles to be lifted in a mutually separated manner. When the long-sized article 2 is brought close to the vertical conveyor device 4, an engagement claw 23 of each platform part 5 is locked to the side part 13a outside of a chain 13 of the corresponding vertical conveyor device 4. In this condition, the long-sized article 2 is fixed to each platform part 5. A driving gear 11 is rotated by driving a driving mechanism 9 of each vertical conveyor device 4, and the chain 13 is driven in the direction where a bar-shaped member 15 of the side part 13a on the platform part engaging side. This constitution allows the long-sized article 2 loaded on the platform part 5 to be lifted upward in the vertical direction.</p> |
