INDUSTRIAL VEHICLE
A wheel loader includes: a driver's cab; an engine; a chassis, at sides of which tires are provided; an engine room in which the engine is mounted on the chassis, the engine room being provided behind the driver's cab; front portion structures respectively standing at left and right positions of a surface of the engine room, the surface being located at the driver's cab side; rear portion structures respectively standing at left and right positions of a surface of the engine room, the surface being opposite to the surface located at the driver's cab side; and a coupling structure that couples upper portions of the front portion structures to upper portions of the rear portion structures and forms a peripheral device installation space at an upper portion of the engine.
1 . An industrial vehicle comprising:
a driver's cab;
an engine;
a chassis, at sides of which tires are provided;
an engine room in which the engine is mounted on the chassis, the engine room being provided behind the driver's cab;
front portion structures respectively standing at left and right positions of a surface of the engine room, the surface being located at the driver's cab side;
rear portion structures respectively standing at left and right positions of a surface of the engine room, the surface being opposite to the surface located at the driver's cab side; and
a coupling structure that couples upper portions of the front portion structures to upper portions of the rear portion structures and forms a peripheral device installation space above the engine.
2 . The industrial vehicle according to claim 1 , wherein:
the engine room includes side covers covering side portions of the engine room, respectively; and
the front portion structures are provided immediately behind the driver's cab and include supporting portions for opening and closing the side covers in a horizontal direction.
3 . The industrial vehicle according to claim 1 , wherein the front portion structures, the rear portion structures, and the coupling structure are integrated with one another to form a frame structure of the engine room.
4 . The industrial vehicle according to claim 1 , wherein:
the front portion structures are provided with a front portion coupling member coupling the front portion structures standing at the left and right positions; and
the front portion coupling member includes a peripheral device installation shelf at which a peripheral device is provided.
5 . The industrial vehicle according to claim 1 , wherein the coupling structure includes a dividing plate dividing the peripheral device installation space into an exhaust system peripheral device installation space and an intake system peripheral device installation space.
6 . The industrial vehicle according to claim 5 , wherein the dividing plate includes a heat insulator configured to prevent heat of the exhaust system peripheral device installation space from being transferred to the intake system peripheral device installation space.
7 . The industrial vehicle according to claim 1 , wherein the rear portion structures are provided with a dividing wall coupling the rear portion structures standing at the left and right positions.
8 . The industrial vehicle according to claim 1 , wherein:
the engine room includes an upper cover covering an upper portion of the engine room;
the upper cover includes a muffler configured to discharge an exhaust gas;
the muffler includes an opening portion through which air in the exhaust system peripheral device installation space is discharged to an outside by an upward flow generated by the exhaust gas discharged from the muffler.
9 . The industrial vehicle according to claim 2 , wherein each of the side covers is formed integrally with a fender for the tire.
