As shown in the figure, the crane device 22 mounted on the aerial work vehicle 23 is provided with an up / down and pivotable bracket 25 at the upper end of a vertical post 24 pivotally supporting the bucket 21. Arm with sheave 26 at the end
The hook 28 attached to the tip of a rope 27 wound around a winch 26 mounted above the bracket 25 is inserted through the base end of the bracket 22a and hung downward through the sheave 26. The operation of transporting equipment or equipment using the crane device 22 is limited to the stroke or the undulation or turning range of the arm 22a, and therefore has various problems such as the difficulty in transporting equipment or equipment. Was.

[Means for solving the purpose and problem of the invention]

The present invention has been made in view of the above-mentioned problems, and a purpose thereof is to attach a pair of arms to the tip of a boom, equip one of the arms with a bucket, and attach a crane device to the other arm. In order to provide an aerial work vehicle that is equipped to enable efficient aerial work,
For this purpose, a turntable mounted on a chassis, an up-and-down boom pivotally attached to the turntable, and an arm having a base mounted on a post balanced at the tip of the boom so as to be swingable in a horizontal plane. And a crane device attached to the tip of the arm, the bucket being swingably attached to the post.

[Action]

With the above configuration, while maintaining the original work efficiency of the aerial work platform equipped with a bucket at the end of the boom, various equipment necessary for the aerial work by using a crane device at the same time And the like can be transported to a worker who is on the bucket, so that work at a high place can be performed very efficiently and the cost can be reduced.

〔Example〕

One embodiment of the aerial work vehicle according to the present invention will be described in detail with reference to FIG.

In the figure, reference numeral 1 denotes an aerial work vehicle according to the present invention. The aerial work vehicle 1 has a subframe 1a mounted on a chassis, and has sufficient strength even when various types of equipment to be described later are mounted. And it is configured to obtain safety.

2 is a sub-frame 1a before and after the sub-frame 1a
The outrigger is provided so as to protrude laterally and extend downward.

Reference numeral 3 denotes a turntable mounted on the rear of the sub-frame 1a.
It is configured to be pivotable with respect to the sub-frame 1a by the operation of a hydraulic motor (omitted in the drawing) incorporated therein.

Reference numeral 4 denotes a multistage boom pivotally supporting a base end of the turntable 3 (in this embodiment, a boom having a three-stage telescopic structure of a base end boom 4a, an intermediate boom 4b, and a front end boom 4c is illustrated).
The undulation of the multi-stage boom 4 is configured to be performed by expansion and contraction of an undulation cylinder 5 pivotally mounted between the turntable 3 and the lower surface of the base end boom 4a.

Also, the middle boom 4b and the tip boom of the multi-stage boom 4
The expansion and contraction of 4c is performed by the expansion and contraction of a telescopic cylinder (omitted in the figure) built in the multi-stage boom 4.

A post 6 is attached to the tip of the tip boom 4c so as to be able to swing back and forth. . Further, a first arm 7a and a second arm 7b which are swingable in a horizontal plane with respect to the post 6 by a swing drive device (omitted in the drawing) are mounted on the post 6 horizontally vertically. A bucket 8 is attached to a tip of the arm 7a so as to swing freely, and a crane device 9 is provided at a tip of the second arm 7b.

Incidentally, the crane device 9 includes an arm 9b having a base end inserted through a bracket 9a provided at the tip of a second arm 7b so as to be able to swing up and down, a winch 9c provided above the bracket 9a, and the bracket 9a. And an undulating cylinder 9d arranged between the arm 9b and one end fixed to the winch 9c,
A hook 9e is attached to the other end, and a rope 9g is fed out and wound by the operation of the winch 9c via a sheave 9f provided at the tip of the arm 9b.

Hereinafter, the operation of the aerial platform vehicle according to the present invention will be described based on the above configuration.

That is, the aerial work vehicle 1 according to the present invention is provided with a first arm 7a swinging in a horizontal plane on a post 6 provided at the tip of the multi-stage boom 4, and the tip of the first arm 7a is swingable. A bucket 8 is attached, an operator is mounted on the bucket 8 to perform a predetermined work at a height, and the post 6 is equipped with a second arm 7b swinging in a horizontal plane, and a tip of the second arm 7b is provided. The crane device 9 is arranged at a predetermined angle, and the arm 9b and the winch 9c of the crane device 9 are raised and lowered at a predetermined angle by a remote control device (not shown) mounted on the bucket 8, for example.
Sheave 9f that is turned and equipped at the tip of arm 9b
By lifting and lowering the hooks 9e suspended through the device, necessary equipment or equipment is transported in the vicinity of the bucket 8 or at an installation place.
In addition to this, it is possible to provide a safe footing for workers at high altitudes with only one aerial work vehicle 1 without introducing crane trucks and the like, and at the same time, equipment or equipment necessary for high altitude work Can be supplied efficiently.

[Effect of the invention]

As described in detail above, the present invention swings in a horizontal plane a turntable mounted on a chassis, an up-and-down boom pivotally attached to the turntable, and a post balanced at the tip of the boom. It consists of an arm with a freely attached base end, a bucket attached to the post so as to swing freely, and a crane device attached to the tip of the arm. It is possible to transport various equipment required for high-altitude work to the workers on board the bucket and to the installation location by using crane equipment while maintaining the efficiency of the work at high altitude. It has various excellent effects, such as being able to perform the work very efficiently and being provided at a low cost.
