The rail member 23 may be reused as an additional connecting rail member. After that, the same vertical movement step as described above and the same transport step as described above are sequentially performed between the upper support device 5 and the additional support device. As a result, the heavy object 3 is transported to the position of the additional support device. Such an operation is repeated until the heavy object 3 reaches the upper part of the stairs 1. In this way, the heavy object 3 is transported to the upper part of the stairs 1.

It can be prevented from being hindered by the support devices 4 and 5. As a result, it is possible to eliminate the work of connecting the heavy object 3 between the two chain blocks, and it is possible to reduce the labor of carrying the heavy object 3. Further, since it is not necessary to prepare a plurality of chain blocks, the number of parts can be reduced and the cost can be reduced.

Further, a pair of guide portions 26 of the lower rail member 21 are arranged below the beam 12 of the lower support device 4, and a pair of guide portions 26 of the upper rail member 22 are arranged below the beam 12 of the upper support device 5. Therefore, the chain block 7 can be moved along the rail 6 without interfering with the beams 12 of the lower support device 4 and the upper support device 5, and the positions of the lower support device 4 and the upper support device 5 are respectively located. It is possible to realize a configuration in which the chain block 7 can pass through with a simple configuration.

Further, in such a heavy object transporting method, after operating either the lower support device 4 or the upper support device 5 to align the positions of the lower rail member 21 and the upper rail member 22 at the same height, the lower stage Since the chain block 7 is moved along the rail 6 while passing through the respective positions of the support device 4 and the upper support device 5, it is possible to prevent the movement of the chain block 7 from being hindered by the support devices 4 and 5. it can.
