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.
