The present embodiment is applied to a large-sized forklift that is a high-cabin type in which a cabin is arranged and supported above a machine base via a pair of left and right pillars and has a container spreader as an attachment. As shown in FIGS. 1 to 3, a large forklift has a pair of left and right frame main plates 1 extending in the front-rear direction as main constituent members of the machine base. They are connected to each other by the cross member 2 at the site.

On the outer surface of the left and right frame main plates 1, a hydraulic oil tank, a fuel tank 3 and a fender 4 are provided.
Steps 5 and the like are provided, and a counterweight 6 is mounted on the rear part. Further, a pair of left and right pillars 7 having a hollow rectangular cross section that is long in the front-rear direction are erected on the left and right sides of the frame main plate 1 approximately in the middle thereof.
The cabin 8 is supported by.

The space between the left and right frame main plates 1 is an engine room, and the engine 9 and its power transmission device, cooling device, etc. (not shown) are provided in the room.
Are arranged, and they are the left and right frame main plates 1
It is covered by an engine hood 10 installed between the upper surfaces. The upper surface of the engine hood 10, the tank 3, the counterweight 6 and the like constitute the upper surface of the machine base.

The engine hood 10 is divided into a front hood 10a, an intermediate hood 10b and a rear hood 10c in the front-rear direction. The front hood 10a formed of a flat plate is horizontally mounted on the left and right frame main plates 1 just below the cabin 8 and is detachably fixed by a bolt (not shown). Further, the rear hood 10c is formed in a substantially gate-shaped cross-section with the front and rear surfaces and the lower surface opened, and is horizontally mounted on the left and right frame main plates 1 and the upper end of the rear hood is openably and closably attached to the counterweight 6. It is worn.

Therefore, although the upper surface of the rear hood 10c is substantially aligned with the upper surface of the counterweight 6, it is higher than the upper surface of the front hood 10a and the front surface is open. Then, the intermediate hood 10b is closed by the front hood 10a so as to close the front open portion of the rear hood 10c.
The intermediate hood 10b is vertically arranged between the rear end of the rear hood 10c and the front end of the rear hood 10c. It is fixed by and can be removed if necessary.

Although not shown, a mast is arranged on the front side of the frame main plate 1, and a container spreader as an attachment is attached to a lift bracket as an elevating member that ascends and descends along the mast.

In the large forklift as described above, an air cleaner 11 for supplying clean air to the engine is arranged between the left and right pillars 7 between the front hood 10a and the cabin 8. That is, the air cleaner 11 is arranged outside the machine base to ensure serviceability of element replacement. The air cleaner 11 has its element 11a (shown in phantom in FIGS. 1 and 2).
The front hood 1 has a detachable part on the front side, and the detaching direction is the front-back direction.
It is attached via a bracket 12 to the inner surface of one pillar 7 in a state of being separated from the upper surface of 0a at a predetermined height position.

As described above, in the present embodiment,
Since the air cleaner 11 is arranged on the outside of the machine base, it is easy to secure a peripheral space necessary for replacing the element 11a. Especially, since the front-rear direction is the detaching direction, the air cleaner 11 is arranged along the vehicle width direction Compared with the case of doing so, it is possible to easily secure a wider space for attachment and detachment without being restricted by the length associated with the interval between the left and right pillars 7. Therefore, the replacement work of the element 11a can be performed more easily than the type installed in the engine room.

When the air cleaner 11 is arranged below the cabin 8, the cabin 8 is installed in the air cleaner 11.
Rainwater works as an air shield for the
It is possible to avoid going directly to. Therefore, the possibility that rainwater will be sucked into the air cleaner 11 and eventually to the engine 9 from the intake port is significantly reduced, and the occurrence of troubles due to the suction of rainwater can be prevented.

Further, the air cleaner 11 has one pillar 7
Since it is attached to the inner surface of the front hood 10a
When removing and performing maintenance and inspection work in the engine room,
The work can be performed with the air cleaner 11 attached, and when the front hood 10a is removed, a wide opening amount of the engine room can be obtained, which facilitates the work. Further, since the air cleaner 11 is arranged on the inner side surface of the pillar 7, the air cleaner 11 can be hidden within the width of the pillar 7 in the front-rear direction, and the appearance of the machine base is not impaired.

In the illustrated embodiment, the air cleaner 11 is arranged so that the element 11a is attached and detached in the front-rear direction, but the arrangement direction may be changed laterally, that is, in the vehicle width direction. Also, the air cleaner 11
Instead of attaching to the pillar 7, it may be installed on the front hood 10a.
