た構造のジブクレーンが知られている。Conventionally, as a jib crane used by mounting on a column, as disclosed in Japanese Utility Model Laid-Open No. 52-9226, the base end of the overhanging arm is horizontally fixed to the upper end of the vertical shaft, and Y on the lower end and the tip and base of the overhanging arm.
The end of the character stay is fixed to form a jib, and the upper and lower parts of the base end of the jib are attached to a clamp fixed to a support post so that they can be horizontally swiveled. There is known a jib crane having a structure in which a guide pulley around which a lifting rope is wound is attached.

昇降運搬には適しないという欠点がある。However, in the case of the above-mentioned conventional jib crane, if the horizontal length of the jib is lengthened, the strength of the jib against the weight of the suspended load becomes weaker, and the horizontal length of the jib is lengthened and wound along the jib. Even when the trolley with the upper device is provided so as to be movable, the strength of the jib is weak, and therefore, there is a disadvantage that it is not suitable for lifting and carrying a heavy load.

補強することができる。According to this invention, the lower slit 9 and the flange 10 rising from both side edges of the lower slit 9 are provided.
The upper end of the vertically extending arm 11 is fixed by welding to both side plates 43 of the base end of the horizontal jib body 4 made of square-section steel, and the horizontal jib body 4 extends from its base end to its middle part. Reinforcing member made of channel steel with extended lip
12, the upper plate 46 of the reinforcing member 12 is superposed on the upper plate 45 of the horizontal jib body 4, and the tip of the lip 42 of the reinforcing member 12 is welded to the side plate 43 of the horizontal jib body 4. To form a jib 5, and the jib 5 has a base end portion of the horizontal jib body 4 and a lower end portion of the arm 11,
A support member 1 is rotatably attached via a vertical axis 6, a column clamp 3 is attached to each support member 1, and a trolley 8 supporting a hoisting device 7 on the jib body 4 is movable. Since it is provided, the welding length can be shortened to economically reinforce the horizontal jib body 4, and the upper plate 46 of the reinforcing member 12 is overlapped with the upper plate 45 of the horizontal jib body 4. Since the horizontal jib body 4 can be reinforced without being bulky in the vertical direction, and since the box of the closed cross section is formed on both left and right sides of the horizontal jib body 4, the horizontal jib body 4 can be extended in the longitudinal direction. Even when the luggage is towed from the intersecting lateral direction, the jib 5 is unlikely to be twisted, so that the jib 5 can be strongly reinforced in both the longitudinal and lateral directions.

る。Further, even if the length of the jib 5 is increased, the strength of the jib with respect to the weight of the suspended load is large, and therefore, even if the moving distance of the trolley 8 supporting the hoisting device 7 is increased, the lifting and lowering of a heavy load is performed. It is possible to carry, and it is possible to obtain an effect that the jib 5 that is relatively lightweight and has high strength can be manufactured.
