A construction machine includes: a cover that covers an engine and a radiator; a radiator fan that is arranged at the rear of a vehicle body frame and discharges exhaust gas toward the rear of the vehicle body frame from the inner space of the cover; an injection device that injects a reducing agent into exhaust gas of the engine; a tank housing section that is arranged at one side of the vehicle body frame, includes an introduction section for introducing outside air, and houses a tank for storing the reducing agent injected by the injection device; and a connection section that is arranged in either the cover or the vehicle body frame and in the tank housing section, connects the inner space of the tank housing section and the inner space of the cover, and allows the outside air and the pipe to pass therethrough, the outside air having been introduced from the introduction section by the suction pressure of the radiator fan, the pipe supplying the reducing agent to the injection device.

Construction machine

A work machine includes: a vehicle body frame of the work machine; an engine mounted on the vehicle body frame; an engine cover covering over a top of the engine and fixed to the vehicle body frame via a column; a first exhausting device having a tubular appearance; a second exhausting device having a tubular appearance and having a function different from that of the first exhausting device; and a bracket holding the first exhausting device in an upper holding part and the second exhausting device in a lower holding part to attach them on a bottom surface of the engine cover. The bracket integrally holds the first and second exhausting devices in such a manner that an extending direction of the first exhausting device and an extending direction of the second exhausting device are generally parallel, seen from above, and a part of the first exhausting device and a part of the second exhausting device overlap each other, seen from above, while fixing the first and second exhausting devices below the engine cover.

Work machine

A clutch control device for an industrial vehicle includes: a braking force detection device that detects braking force of the industrial vehicle; a speed stage detection device that detects a set speed stage of a transmission; a clutch control device that controls engage/release of a forward clutch so that the forward clutch is released when a clutch cut off condition is judged to be satisfied based upon braking force of the industrial vehicle detected by the braking force detection device; and a switching device that automatically switches the clutch cut off condition in the clutch control device based upon a set speed stage of the transmission detected by the speed stage detection device.
