Wheel loader

A step of an industrial vehicle according to the present invention includes: an upper footboard fixed to a side surface of the industrial vehicle; a turning mechanism provided at a rear side of the upper footboard; a front suspension member extending downward from a front portion of the upper footboard and having elasticity; a rear suspension member extending downward from the turning mechanism and having elasticity; and a lower footboard held by the front suspension member and the rear suspension member, wherein: an upper portion of the front suspension member is fixed to the front portion of the upper footboard so as to be non-turnable; a lower portion of the front suspension member is fixed to a front portion of the lower footboard so as to be non-turnable; a lower portion of the rear suspension member is fixed to a rear portion of the lower footboard so as to be non-turnable; and an upper portion of the rear suspension member is coupled to a rear portion of the upper footboard through the turning mechanism so as to be turnable around an axis extending in a vehicle width direction.

Step of industrial vehicle and industrial vehicle

A cooling structure of an operating machine, such as a wheel loader, which structure cools an engine of the operating machine includes: a cover (such as a rear cover) forming a part of an outer surface of a vehicle body of the operating machine and including a large number of ventilation opening portions; a radiator provided at the vehicle body so as to be opposed to the cover; and a cooling fan arranged between the cover and the radiator and close to the cover with an interval corresponding to a size of the ventilation opening portion and provided so as not to be turnable relative to the vehicle body.

Cooling structure of operating machine and operating machine

An industrial vehicle includes: an exhaust gas treatment device arranged in an engine room so as to be located above an engine, the exhaust gas treatment device including a pretreatment unit accommodating a diesel oxidation catalyst and extending in the forward/rearward direction, a selective catalytic reduction unit located adjacent to the pretreatment unit and extending in the forward/rearward direction, a connecting pipe including a mix portion, a first bent portion, and a second bent portion, the mix portion being located between the pretreatment unit and the selective catalytic reduction unit and extending in the forward/rearward direction, the first bent portion connecting the mix portion and an outlet of the pretreatment unit, the outlet being located close to a dividing wall, the second bent portion connecting the mix portion and an inlet of the selective catalytic reduction unit, the inlet being located far from the dividing wall, and a urea water injection device attached to the first bent portion of the connecting pipe so as to be located on an extended line of the mix portion and configured to inject urea water into an exhaust gas; a urea water tank arranged outside the engine room and storing the urea water; and a urea water pipe configured to guide the urea water from the urea water tank to the urea water injection device and penetrating the dividing wall.

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.
