2. Description of the Related Art Generally, a forklift has a structure in which a battery, an air tank for braking, a condenser for cooling, and the like are housed on the side surface of the vehicle body. For example, in the case of the relatively large forklift truck shown in FIGS. 7 and 8, the battery 33, the condenser 34, etc. are placed on the outer side of the upper surface of the first step 32 provided on the side frame 31 of the vehicle body, and the opening / closing is performed. It is covered by a removable or removable side cover 35, and a fuel or hydraulic oil tank 36 (hereinafter,
A hydraulic oil tank) is installed. A second step 37 is constituted by the upper surface of the side cover 35 or the upper surface of the hydraulic oil tank 36, and the third step 39 is welded to the corner portion of the side frame 31 and the front fender 38 for the front wheels to form the upper and lower parts. A step device for getting in and out of steps is configured.

The examples shown in FIGS. 9 and 10 are for a medium-sized or small-sized forklift truck, and a hydraulic oil tank 42 is fixed to a side frame 41 of the vehicle body. Battery 43 and capacitor 4
4 and the like are placed and covered by the side cover 45. The first step 47 is welded to the outer side surface of the hydraulic oil tank 42 and the fender 46, and the upper surface of the hydraulic oil tank 42 is used as the second step 48 to form a two-step upper / lower step device. .

[0004]

However, in the case of the above-described conventional forklift, in the three-step step device applied to the former large forklift shown in FIGS. 7 and 8, the battery 33 and the condenser 34 are used first. Since it is placed and stored on the upper surface of step 32, the arrangement position is low, so there is a problem that the setting of the storage space is limited by the front and rear fenders, and the maintenance work of the storage device in a crouched posture with forward bending. On top of that,
There is a problem in that it is easily affected by muddy water.

On the other hand, like the latter shown in FIGS. 9 and 10, the battery 43, the condenser 44, etc. are connected to the hydraulic oil tank 42.
If the structure is to be mounted on the upper surface of the above, they can be arranged at a high position, which is convenient in this respect without the above-mentioned problems. However, if such an arrangement structure is applied to a large-sized forklift to construct a three-step upper and lower step device including a third step, the third step includes the front fender 38 and the side fender 38 as shown in FIGS. 7 and 8. Since it is attached to the corner of the frame 31 by welding, the storage space for the battery or the like is reduced. In that case, even if the storage space is set on the back side of the third step, it is necessary to form the side cover in a shape that avoids interference with the third step. Becomes smaller and the serviceability deteriorates.

In view of the above-mentioned circumstances, the present invention provides a step apparatus for getting on and off an industrial vehicle, in which a storage space for a battery or the like can be set sufficiently wide and a maintenance work for the battery or the like is suitable. Is a technical problem to be solved.

[0007]

In order to solve the above problems, the present invention is configured as follows. That is, a stepping device for an industrial vehicle in which a storage space for a battery or the like is formed on a side surface of a vehicle body, and a side cover is attached so as to cover the storage space,
The side cover is divided into front and rear, steps are integrally formed on the divided front side side cover, and the steps are detachably fastened to the front fender for covering the front wheels with mounting bolts. It is characterized by that.

[0008]

In the stepping apparatus for getting on and off according to the present invention constructed as described above, the step is always fixed to the front fender, and acts as an getting on and off step for the occupant. On the other hand, when carrying out maintenance work on a storage device such as a battery, opening / closing or removal of the rear side cover is not hindered. Further, since the step itself is integrated with the front side cover and is fastened to the front fender with the mounting bolts, when the rear side cover and the rear side cover are both removed, the storage space for the battery and the like can be largely opened.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. The step apparatus for getting on and off according to the present embodiment is applied to a large forklift as shown in FIG.
As shown in the figure, a hydraulic oil tank (or fuel tank) 1 whose front side width is set to be slightly narrower than that of the rear side is formed on the side surface of the vehicle body. The first step 4 having a substantially triangular shape is fixed by welding to a corner with the fender.

A second step 5 is formed by the outer (upper side) upper surface of the hydraulic oil tank 1, and a storage space for storing the battery 6, the condenser 7, etc. on the rear upper surface of the hydraulic oil tank 1. Is set. Although not specifically shown, the storage space has a bottom formed by the hydraulic oil tank 1, and the front and rear surfaces are closed by the fender 3, the toe board, the side frame, and the like. It is shaped like a long rectangle. That is, the space on the back side of the upper surface of the hydraulic oil tank 1 is set as a storage space for the battery 6 and the like, and the outer opening of this storage space is covered by the side cover 8.

The side cover 8 has a two-divided structure in the front-rear direction. More specifically, it is divided at a position closer to the front of the fender 3, and the rear side cover 8a is set to a large size having a size capable of covering most of the opening of the storage space such as the battery. Although not attached, it is attached to the opening by a hinge or a catch so that it can be opened and closed or detached. On the other hand, the front side cover 8b has a smaller size than the rear side cover 8a, and the third step 9 is fixed to this. As shown in FIGS. 1 to 3, the third step 9 is formed in a substantially channel shape, and is welded to the outer surface of the front side cover 8b while being abutted with the channel direction thereof in the front-rear direction. The front end surface of the third step 9 is formed in a curved surface corresponding to the curved shape of the fender 3 together with the front side cover 8b, and is aligned with the end surface of the front side cover 8b.

In the third step 9, however, two left and right mounting holes 10 are provided on the front side of the upper surface which is the step surface.
Further, a mounting plate 11 is welded in a lateral bridge shape at a lower center portion between the left and right side plates in the third step 9, and the mounting plate 11 is
Two mounting holes 12 are formed on the left and right. Correspondingly, upper and lower mounting bases 14 having weld nuts 13 are mounted on the rear surface side of the fender 3. That is,
In the third step 9, the front side cover 8b and the front end surface of the front side cover 8b are in contact with the rear curved surface of the fender 3 and the mounting bolts 15 are attached to the weld nuts 13 of the upper and lower mounting bases 14.
Is detachably fixed by tightening through the mounting holes 10 and 12.

In the boarding / alighting step device of the present embodiment constructed as described above, when performing maintenance work such as maintenance inspection and replacement of the battery 6, the capacitor 7, etc., the side cover 8 is basically used. By opening or removing the rear side cover 8a, a side of the storage space for the battery or the like can be opened to perform a predetermined maintenance work. In this case, if necessary, the third step 9 is further performed on the front side. A wider opening amount can be obtained by removing the side cover 8b together with the fender 3.

That is, when the third step 9 is fixed to the front sight cover 8b and is removably attached to the fender 3 as in the present embodiment, the battery is provided on the rear side of the third step 9 as well. Since a storage space such as 6 can be formed, the space can be set sufficiently wide, and the maintenance work of the storage device can be easily performed. Further, since the storage space for the battery and the like is set on the back side upper surface of the hydraulic oil tank 1, it is possible to position it from the waist to the vicinity of the chest, and to perform maintenance work in a comfortable posture. It has the advantage that it is unlikely to be affected by the muddy water splashed up at.

Next, another embodiment of the present invention will be described with reference to FIGS. This embodiment is a modification of the mounting structure of the third step 9 for the fender 3,
This is devised so that the head of the mounting bolt 15 does not appear on the step surface. That is, the mounting plate 17 having the mounting holes 16 is vertically welded to the lower surface side of the upper plate that constitutes the step surface of the third step 9, and the upper mounting pedestal 14 on the fender 3 side corresponds to this. It is formed in the shape. The rest of the configuration is similar to that of the above-mentioned embodiment. Therefore, according to this embodiment, since the head of the mounting bolt 15 does not project to the step surface, the appearance is improved, and the safety is improved by avoiding a stumbling or catching when getting on or off. It
