の回りに移動する。 To assemble the crane according to the first embodiment of the present invention, proceed as follows. First, the jack part 1 is attached to the lower end of the vertical pole 2, and the spherical bearing 14 is attached to the lower end of the jack part 1 and the upper end of the vertical pole 2.
Attach the pressing member 15 (FIG. 7) via. Next, the forked portion 18 of the horizontal member 5 shown in FIGS. 2 and 3
The mounting part 16 of the vertical pole 2 is sandwiched between the poles, the round bar insertion holes 17 and 19 of both are aligned as shown in FIG. Next, the end projecting member 9 is attached to one end of the horizontal member 5 with a bolt 24 as shown in FIG. At this time, the height from the horizontal member 5 to the upper end of the wheel 6 and the height from the horizontal member 5 to the pressing member 15 are configured to be equal. Next, vertical pole 2
The length between the pressing surfaces 7, 7 at both ends is made slightly smaller than the distance between the floor surface 31 and the ceiling surface 32, and the crane of the present invention is made to stand upright on the floor surface 31. Next, rotate the handle 13 of the jack part 1 to extend the vertical pole 2, and touch the pressing surfaces 7, 7 at both ends to the ceiling surface 3, respectively.
2 and the floor surface 31. And Natsuto 3
4 to prevent the jacking part 1 from loosening,
Remove the handle 13. Then, vertical pole 2
The wheels 6 stand on their own, and the upper surfaces of the wheels 6 touch the ceiling surface 32. In this way, the crane of the present invention can be easily and quickly self-supported at an appropriate position within the building. Then,
A load 33 having a weight of W is lifted up by a chain block 25 which is engaged with a lifting part 4 of a horizontal member 5. At this time, the horizontal member 5 is pivotally attached to the vertical pole 2 by a round bar 20. Therefore, no bending moment is applied to the vertical pole 2, and the load W is applied to the vertical pole 2 as a vertical load via the round bar 20. The maximum moment W·l applied to the right side of the vertical pole 2 on the horizontal member 5 in FIG. 1 is the reaction force W 1 from the ceiling contact surface 3 of the wheel 6
is balanced by the product W 1・l 1 with length l 1 . Here l and
l 1 is the distance from the vertical pole 2 to W and W 1 as shown. From the above, since no bending moment is applied to the vertical pole 2, the load 33 can be safely lifted without any force acting to cause the vertical pole 2 to fall. Next, when the load 33 is lifted and pushed horizontally, the vertical pole 2 rotates via the rotatable means 8, and the load 33 is moved to the vertical pole 2.
move around.
本発明のクレーンは以上のような構成からな

Since the crane is pivotally connected to the vertical pole 2, only a vertical load can be applied to the vertical pole 2, and no overturning force is applied to the pole 2, allowing the crane to stand on its own safely and reliably. At the same time, the main parts of the crane can be assembled and disassembled by attaching and detaching the round rod 20, etc., which are pivot members, making it convenient to carry the crane.
Furthermore, since wheels 6 are provided on the horizontal member 5 and rotatable means 8 are provided between the horizontal member 5 and the pressing surface 7, the lifted cargo can be moved around the vertical pole 1 via the wheels 6 for contacting the ceiling surface. You can move smoothly.
