[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerial work vehicle used for ceiling work at a building construction site, and more particularly, to a wire rope used for lifting an aerial work vehicle with a crane and moving it to the work site. The present invention relates to an aerial work vehicle that can be efficiently mounted.

[0002]

2. Description of the Related Art Aerial work vehicles used at construction sites, etc.
When transporting to a work place, there was a case where it was carried using a crane. When hoisting the aerial work vehicle with a crane, for example, as shown in FIGS. 4 and 5, shackles 22 for attaching a plurality of wire ropes are attached to both sides of the base 21 of the aerial work vehicle 20. A wire rope 24 was passed around the shackle 22 outside the worktable 23.

[0003]

However, in the above-mentioned construction, when the aerial work vehicle 20 is lifted by the crane, the wire rope 24 comes into contact with the handrail 25 protruding from the work table 23. There is a possibility that the contact portion of the handrail 25 may be damaged or deformed, and the paint may be peeled off. In addition, since the wire rope 24 must be wrapped around the outside of the worktable 23, it takes time and effort for the slinging operation.

Accordingly, an object of the present invention is to provide an aerial work vehicle capable of preventing a wire rope from being in contact with an aerial work vehicle as much as possible when being lifted by a crane, and capable of easily performing sling work. .

[0005]

According to the present invention, a scissors link mechanism is provided between a base and a work table, and the work table is raised and lowered by the scissors link mechanism. In the car, in the upper four places of the base,
A bracket for attaching a wire rope and a shackle is provided, and an openable door is provided at a position corresponding to the bracket on the floor of the worktable.

[0006]

[Action] By this, open the door provided on the floor of the work table,
When the workbench is lowered to the lowest position, the wire rope mounting bracket projects from the floor of the workbench through a through hole formed by opening the door. By attaching a wire rope to this bracket via a shackle, etc.
Even if the aerial work platform is hung by a crane, the wire rope can be prevented from contacting the workbench or the handrail of the workbench.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention.
The aerial work vehicle 1 has a scissors link mechanism 4 disposed between a movable base 2 and a work table 3. The work table 3 is moved up and down by opening and closing the scissor link mechanism 4. ing.

On the upper surface 2a of the base 2, four shackles 6 are provided via brackets 5 at positions substantially symmetrical from the position of the center of gravity of the aerial work vehicle 1. The shackle 6 attached to the bracket 5 is attached in a direction in which the extension lines intersect at one point, as shown by the broken line in FIG.

The work table 3 is a rectangle having a slightly larger area than the upper surface 2a of the base 2, and a door 7 which is opened and closed by a hinge is provided on the floor 3a at a position corresponding to each bracket 5.
An operation panel 8 is provided on the front side of the work table 3, and by operating the operation panel 8, the aerial work vehicle 1 is operated.
, The work table 3 is moved up and down, and the like. Further, a handrail 9 is provided on the entire outer periphery of the work table 3.

When the aerial work vehicle 1 formed as described above is lifted and moved by a crane, the work table 3
With the doors 7 open, the workbench 3 is lowered to the lowest position, and the shackle 6 attached to the bracket 5 is projected from a through hole formed by opening each door 7. In this state,
The worker can get on the worktable 3 and attach the wire ropes 10 to the respective shackles 6 to easily finish the slinging operation. As shown in FIG. , The aerial work vehicle 1 can be lifted. When a worker works on the workbench 3 of the aerial work vehicle 1 at the work site, the worker can work safely by closing the doors 7.

As described above, by attaching the wire rope 10 to the shackle 6 protruding from the work table 3,
When the aerial work vehicle 1 is lifted by the crane, the contact portion between the wire rope 10 and the aerial work vehicle 1 can be reduced as much as possible. Therefore, there is no possibility that the handrail 9 of the work table 3 is deformed or the coating is peeled off by the wire rope 10 as in the related art, and the wire rope 10 comes into contact with the aerial work vehicle 1 and is damaged. Is also gone. Further, since each shackle 6 is attached to the bracket 5 where the extension line intersects at one point, the load on each shackle 6 and the bracket 5 can be minimized.

[0012]

[Effects of the Invention] As described above, the present invention provides brackets for attaching wire ropes to the upper four places of the base of an aerial work vehicle, and opens and closes at positions corresponding to the brackets on the floor of the work table. Since a possible door is provided, the contact portion between the wire rope and the aerial work vehicle can be minimized when the aerial work vehicle is lifted by the crane. For this reason, unlike the conventional art, there is no possibility that the handrail of the workbench is deformed or the paint is peeled off by the wire rope, and the wire rope is not damaged.

[0013] Furthermore, slinging work becomes easy, and safe work can be performed in a short time.
