BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerial work vehicle widely used for power distribution work and construction work. In addition, the "stairs" in the present invention refers to those that can easily go up and down without supporting the body with hands, and are distinguished from "ladders" that normally go up and down while supporting the body with hands.

[0002]

2. Description of the Related Art An aerial work vehicle such as the one described above has a platform (a portion corresponding to a cargo bed in a truck) on which a tool or the like used for the above-mentioned work can be stored as much as possible.
A large storage (also called a large tool box) is often provided. For example, the aerial work vehicle 40 shown in FIGS.
At the center of the front part of a chassis 41 provided behind the driving cabin 42, a swivel base 43 extending higher than the ceiling surface of the driving cabin 42 is attached. A work table 45 is mounted on the end of the boom 44. An operator riding on the work table 45 allows the turntable 43 and the boom 4 to move.
By the operation of 4, it is possible to move to an arbitrary height and perform construction. Further, over a substantially entire surface of the undercarriage 41 except the periphery of the swivel base 43, a large storage 48 having a width and a height substantially equal to that of the driving cabin 42.
Is attached. In addition, this large storage 48
It has a space continuous in the width direction of the chassis 41 therein, so that a considerably large tool or the like can be stored. Also, as shown in the figure, doors 48d are provided on both side surfaces of the large storage case 48, so that stored items can be taken in and out from either side, which is convenient. In the aerial work vehicle 40, the work table 45 is stored above the rear of the large storage 48 by the operation of the swivel table 43 and the boom 44.

On the other hand, in the aerial work vehicle 60 shown in FIGS. 6 and 7, similarly to the aerial work vehicle 40 described above, a swivel platform extending higher than the ceiling surface of a driving cabin 62 is provided at the front center of a chassis 61. A boom 64 is mounted on the upper end of the boom 64 so that the boom 64 can be raised and lowered, and a worktable 65 is mounted on the end of the boom 64. However, the large storage 68 having substantially the same height as the driving cabin 62 is divided and attached to both sides in the width direction of the undercarriage 61 with the swivel 63 interposed therebetween, and one of the storages (hereinafter referred to as a large storage). 68a is attached from the right front end to the right rear end of the chassis 61, and the other storage (hereinafter referred to as small storage) 68b is installed from the left front end to the left middle of the chassis 61. In addition, in this aerial work vehicle 60,
The boom 64 is inserted into the space between the back surfaces of the storages 68a and 68b by the raising and lowering operation, and
The rear of the large storage 68a and the small storage 68
b is stored in the space surrounded by the rear end face. Therefore, the worker can relatively easily get on and off between the work platform 65 and the chassis 61 lowered to a position lower than the chassis 61 in this way.

[0004]

However, in the former case, the work table 45 (or the ground) and its work table 4 are stored because the work table 45 is stored at a position higher than the work table 41.
5 must be performed using a ladder 49 vertically attached to the rear end of the large storage 48, and there is a problem that it is difficult for the operator to get on and off. In particular, for example, even when it is desired to lift various tools or the like with the hand on the work bench 45, the hand is often blocked to support the body with respect to the ladder 49, and therefore, it often does not go smoothly. On the other hand, in the case of the latter, the space that can be used for the storage is narrowed by the storage space of the boom 64 and the workbench 65, so that there is a problem that the storage capacity is considerably reduced as compared with the former.

The present invention has been made in view of the above problems, and provides an aerial work vehicle that can secure a sufficient storage space on a chassis and can easily get on and off a platform. It is intended to be.

[0006]

In order to achieve the above-mentioned object, an aerial work vehicle according to the present invention is provided at a front portion of a chassis provided behind a driving cabin in a truck, and is capable of turning with respect to the chassis. Attach the revolving base, pivot the boom up and down on the upper part of the revolving base, attach the work table to the tip of the boom, and have the same width as the chassis from the front end to the middle part on the chassis, Inside, a first storage portion having a space continuous in the width direction except for the periphery of the swivel, and one side end on the chassis from the rear of the first storage portion to the rear end of the chassis. A second storage portion is provided leaving a partial space in the width direction behind the portion, so that the working table is stored above the second storage portion by the operation of the swivel table and the boom, Some of the above spaces have chassis and It is configured with a stepped used for getting on and off with the workbench in the pay state.

[0007]

In such an aerial work vehicle, for example, by setting the first storage section and the second storage section to a height substantially equal to the driving cabin, the aerial work vehicle shown in FIG. 4
Compared to zero, it is possible to suppress only a decrease in storage capacity for the above-mentioned partial space where the stairs are attached (there is even less if storage spaces are provided below the stairs, etc.). On the other hand, getting on and off between the undercarriage and the stored workbench can be performed easily using the stairs while holding tools and the like.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. The aerial work vehicle 10 according to the present invention
As shown in FIGS. 1 to 3, at the center of the front of a chassis 11 provided behind the driving cabin 12 in the truck T, the truck T can be freely turned with respect to the chassis 11 and from the ceiling surface of the driving cabin 12. A revolving base 13 is attached to the upper part of the revolving base 13, and a boom 14 configured to be extendable and retractable is pivotally mounted on the upper part of the revolving base 13 so as to be able to move up and down.
