If the lifting machine 10 is moved toward the road 4 in this state, the frictional resistance of the trolley 15 accommodated in the fixed rail 8 when traveling is smaller than the frictional resistance of the trolley 15 accommodated in the moving rail 9 when traveling. Therefore, the moving rail 9 moves toward the road 4 in conjunction with the lifting machine 10. When the trolley 15 on the road 4 side in the fixed rail 8 is stopped by the stopper 16 described above and the movement of the moving rail 9 stops, one end 9A of the moving rail 9 exceeds the one end 8A of the fixed rail 8 and the road 4 is moved. , And only the crane 10 moves to the road 4 side. If the hoist 10 is moved to a position where the trolley 15 in the vicinity of one end 9A of the moving rail 9 or the moving rail 9 is stopped by the stopper 16 and the movement of the hoist 10 is stopped, the hoist 10 is also over the road 4. Since it is located, the building member 6 can be lifted by the hoisting machine 10 if the truck 25 or the like loaded with the building member 6 is parked on the road 4 near the dedicated passage 5.
[0032]
When transporting the building member 6, first, the lifted building member 6 and the like are gripped and moved together with the lifting machine 10 to the building site 3 side. If the lifting machine 10 moves to the vicinity of the longitudinal center of the moving rail 9, the frictional resistance of the trolley 15 in the fixed rail 8 when the trolley 15 runs in the moving rail 9 is the same as described above. The lifting machine 10 and the moving rail 9 move in conjunction with each other to move to the building site 3 side. When the trolley 15 on the building site 3 side in the fixed rail 8 is stopped by the stopper 16 described above and the movement of the moving rail 9 stops, the other end 9B of the moving rail 9 becomes the other end 8B of the fixed rail 8. , And overhangs the building site 3, and only the lifted building members 6 and the lifting machine 10 move to the building site 3 side. If the building member 6 is moved together with the lifting machine 10 to a position near the other end 9B of the moving rail 9 or the trolley 15 in the moving rail 9 is stopped by the stopper 16 and the movement of the lifting machine 10 stops, the building member 6 and Since the lifting machine 10 is located above the building site 3, the building member 6 can be lowered to the building site 3. When transporting the building member 6 again, the same operation as described above may be repeated.
[0033]
As described above, according to the transport method using the transport device 1 described above, the building member 6 can be easily transported from the road 4 to the interior of the building site 3 without accompanying physical labor on the flagpole type site 11 and the like. The moving rail 9 and the hoisting machine 10 can be accommodated in the dedicated passage 5 except during the work of transporting the building members 6, so that there is an advantage that traffic on the road 4 is not hindered.
[0034]
Here, the other end 9B of the moving rail 9 extends beyond the other end 8B of the fixed rail 8 into the movable range 12a of the overhead crane (not shown) provided on the ceiling of the scaffold 12 described above. With the other end 9B of the moving rail 9 extending beyond the other end 8B of the fixed rail 8 and projecting into the movable range 12a, the suspended building member 6 is moved within the movable range 12a. In this case, the building member 6 transported from the road 4 by the lifting machine 10 can be lowered into the movable range 12a of the overhead crane. Therefore, there is an advantage that it is not necessary to carry the building member 6 by hand even in the building site 3.
[0035]
