However, it is dangerous to hang long materials obliquely. Such transport is not performed. Usually, a large temporary opening is secured on the floor or the like for transporting long material, and the long material is transported horizontally underground using the temporary opening as a hoistway. However, if the temporary opening is formed large, there is a disadvantage that the work area on the ground is reduced, and at the same time, it is necessary to construct the temporary opening after the completion of the construction work, which is disadvantageous in the process and uneconomical. On the other hand, it is also possible to shorten the length of the material and carry in the material from the opening without making the temporary opening too large, and after carrying in the material, the short material may be used by connecting it long using a joint or the like. Has been done.

ズに降ろせるようにすることを目的とする。Among the conventional methods for transporting long materials, when the temporary opening is formed large and transported, as described above, the work area on the ground is reduced, and the temporary work is completed after the construction is completed. The work of closing the opening is difficult.
Also, when the temporary opening is formed small, there is no problem described above, but after transporting the short material through the temporary opening, it is necessary to connect to a long material by a lap joint, a mechanical joint, gas welding, etc. Disadvantageous for work,
It is uneconomical. Accordingly, the present invention provides a method for producing long materials without forming a large temporary opening provided on a floor such as a construction site.
The object is to enable the material to be transported without being shortened and to be transported as it is, and to be able to transport the material safely without dropping, and to transport the long material and allow it to be smoothly dropped on the floor. .

There is a difference in the height position of the hooks at both ends of the rope,
Long materials fall down. When tilting, operate so that the fall prevention basket side inserted into the end of the long material becomes the lower side,
In addition, the fall prevention basket is hung on the hoist via the third wire, the locking portion of the second and first wires, and the cable connected to the reversing machine, so that the long material is lifted almost vertically and dropped. The bottom plate surface of the prevention basket can support the lower part of the long material. Therefore, even if the long material is tilted, the material can be transported safely without dropping. In addition, when lowering inclined long materials on a horizontal surface after transportation,
Since the casters provided in the fall prevention basket roll on a horizontal plane, the suspended load can be smoothly transferred. Furthermore, since the fall prevention basket has a guide plate at the opening,
It is easy to insert and pull out the long material, and the basket surface opposite to the rolling surface side of the fall prevention cage can swing and open, so the fall prevention basket can be removed from the end of the long material. Even when there is no space to insert the basket, the fall prevention basket can be inserted into the material by opening the basket surface and dropping the long material from above.

２参照）。Further, a box-shaped fall prevention basket 15 is inserted into one end of the long material 9, and the center of the third wire 13 having both ends connected to both sides of the opening of the fall prevention basket 15 is connected to the second wire. The wire 12 is made to penetrate one of the metal fittings 14,
The hoisting force of the hoist 1 acts on the third wire 13 when the long material 9 is tilted. The fall prevention basket 15 is
The frame is formed in a substantially rectangular parallelepiped, and one of two opposing surfaces of the hexahedron is formed on the bottom plate surface 153, and the other is formed on the opening 154. In the above, the third wire 1
3 was penetrated through the latch 14, but the latch was movably provided at the center of the third wire, and the latch was connected to the connecting portion (the first wire 11) of the first wire 11 and the second wire 12. 1
(Including only the wire).
Then, by operating the hoist 1, the long material 9 is lifted horizontally via the reversing machine 4, the cords 5, and the first wire 11, and is horizontally moved and moved onto the temporary opening 16 provided on the floor. At that position, the control panel 7 is operated by the hand switch 7a to operate the reversing machine 4, and the cable 5 is rotated to lock the hooks 5 at both ends.
a, 5a so that there is a difference in height. In this case, the position of the hook 5a on the fall prevention basket side is set lower than that of the other hook 5a, and the difference between the hooks 5a causes the end of the long material 9 into which the fall prevention basket 15 is inserted to fall down ( (See FIG. 2).

をスムーズに移動することができる。According to the present invention, a long material in a horizontally lifted state is tilted by a reversing machine to reduce the projected area. Therefore, even if the temporary opening at the construction site is small, it can be passed up and down. Since the work can be conveyed and the temporary opening does not need to be enlarged, the work area is not reduced, which is advantageous in work, and the work of closing the temporary opening after the completion of the construction is economical because the work is easy. Further, even if the length of the material is sufficiently ensured, there is no problem in the transportation, so that the number of parts to be connected by the joint is reduced, and the construction schedule becomes easy and the number of work steps can be reduced, so that it is economical. In addition, a drop prevention basket is inserted into one end of the long material, and the lifting force of the hoist acts on it, so even if the long material is tilted, there is no danger of the material falling and there is no danger of falling. Can be transported. Further, the fall prevention basket can be easily inserted into or pulled out from the long material, and the long material can be transported safely without falling.
Moreover, since the casters are provided, the long material of the suspended load can be smoothly moved.
