Abstract

A fire wall for defining an engine room and a tank chamber is disposed in a body. The fire wall is provided with a tool storage section. Direct conduction of heat from a hydraulic oil tank to the tool storage section is prevented. Even if hydraulic oil stored in the hydraulic oil tank becomes hot, increase in the temperature of the tool storage section is limited. A sufficient space for storage of tools is ensured.

Claims (28)

1. A work machine comprising:

a main body,

a working unit mounted on the main body and adapted to be operated by hydraulic actuators,

a partition installed in the main body so as to define:

an engine room, which contains at least an engine, and

a tank chamber, which contains at least a hydraulic fluid tank for storing hydraulic fluid to be supplied to and discharged from said hydraulic actuators, and a tool storage section that is provided at said partition and serves to store tools.

2. A work machine as claimed in claim 1 , wherein:

the tool storage section is provided at the side of the partition that faces the engine room.

3. A work machine as claimed in claim 2 , wherein:

the partition is provided with a cutout portion at a location where the partition defines a part of the lip of the opening of the tool storage section.

4. A work machine as claimed in claim 2 , wherein:

the work machine is provided with a storage section forming plate to be attached to a side planar portion of the partition from the engine room-side so as to form, together with the partition, said tool storage section.

5. A work machine as claimed in 3 , wherein:

the work machine is provided with a storage section forming plate to be attached to a side planar portion of the partition from the engine room-side so as to form, together with the partition, said tool storage section.

6. A tool storage section for a work machine including a main body,

a working unit mounted on the main body and adapted to be operated by hydraulic actuators,

a partition installed in the main body so as to define:

an engine room, which contains at least an engine, and

a tank chamber, which contains at least a hydraulic fluid tank for storing hydraulic fluid to be supplied to and discharged from said hydraulic actuators, and a reinforceing plate disposed on said partition; comprising:

a first side plate portion disposed on said reinforcing plate;

a second side plate portion disposed on said portion and attached to said first side plate; and

a bottom plate disposal on said first side plate and said second side plate; and

wherein said first side plate, said second side plate and said bottom plate forming an interior volume therein.

7. The tool storage section of claim 6 , wherein a top end of said first side plate is angled downward toward said second side plate.

8. The tool storage section of claim 6 , further comprising:

a cutout portion forming an opening to said interior volume.

9. The tool storage section of claim 6 , wherein a front cover attached to a mounting plate portion of the partition closes said tool storage section.

10. The tool storage section of claim 6 , wherein said tool storage section is disposed on a side of the partition facing the engine room.
