Abstract: A tilt-up mechanism for tilting up an upper column of a steering column from a drive position to a tilt-up position is configured independently from a tilt angle adjusting mechanism and a column length adjusting mechanism. When an operator who is to get on/off an operator's seat steps on and operates a pedal of the tilt-up mechanism, an engaged state of a lock pin with respect to a tilt-up member is disengaged. The tilt-up member is rotated around a support shaft, by a spring force of a tilt-up spring, whereby the upper column is tilted up together with a steering wheel in a direction (A) away from the operator's seat. At this time, the tilt angle and the column length can be held at positions adjusted in advance.

Abstract: A wheel loader includes a vehicle body having wheels a work implement including an arm, a bucket, and an arm cylinder and a bucket cylinder that drive the arm and the bucket, respectively, and a work implement control device that directs an operation of the work implement. The work implement control device includes an arm control lever disposed on the right of a driver's seat, the arm control lever controlling operations of the arm, and two kickdown switches disposed at an upper surface and a left side surface, respectively, of a grip of the arm control lever. Operability can thereby be improved even further.

Abstract: In a heat exchanger cover (17) covering upper sides of heat exchanger (13), an inlet port (21) is provided on a left side which is an upstream side of cooling air, and one exhaust port (22) for exhausting the cooling air which has passed through the heat exchanger (13) is provided on a right side opposite to this inlet port (21). An engine cover (15) is provided with another exhaust port (23) at a position opposing the one exhaust port (22) in a left-right direction. The cooling air which has passed through the heat exchanger (13) can be exhausted horizontally from the exhaust port (22) provided in the heat exchanger cover (17) toward the exhaust port (23) provided in the engine cover (15).

Abstract: A machine room (15) is provided between a cab (14) and a counterweight (6) which are mounted on a revolving frame (5) to accommodate an engine (7). The machine room (15) is built of a left front support member (20), a rear support member (21), a connecting support member (22) and a left side housing door (25). A horizontal grip portion (22B) and an inclined grip portion (22C) are provided in intermediate portions of the connecting support member (22) which connects the left front support member (20) and the rear support member (21). By opening the left side housing door (25), the inclined grip portion (22C) of the connecting support member (22) comes out, permitting a servicing worker to hold on thereto helping him or her perform a cleaning job of a rear face portion (14B) of a cab (14) in an efficient manner.
