    摘要: 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.

    摘要: A work machine gear shifting control system provides gear shifting conditions for an automatic gear shifting mode in accordance with work site conditions. An area 62 of a display device 49 displays a permissible velocity setting range and setup operation guidance, and another area 64 shows guidance to indicate whether the setting is acceptable or unacceptable. When the traveling velocity falls within the permissible velocity setting range, the displayed guidance changes to indicate that the setting is acceptable. When, in this instance, an operator presses a setup switch 23 with desired timing, a transmission gear shifting control section 45 acquires the prevailing vehicle velocity and velocity ratio (or vehicle velocity), and stores adjustment values in an adjustment value storage section 43 so that the vehicle velocity and velocity ratio become the gear shifting control threshold values for normal gear shifting control (steps S535 to S545).

    摘要: A forward/reverse control system for a work machine cancels a second control state, in which forward/reverse switching control is performed by a second forward/reverse control means, by an operation of a first forward/reverse control means to return to a first control state in which forward/reverse switching control is performed by the first forward/reverse control means. The system is provided with a F-N-R lever unit 30 (the first forward/reverse control means) and F-N-R switch unit 40 (the second forward/reverse control means) that instruct forward, reverse or neutral, a controller 42 which performs forward/reverse switching control by giving priority to an instruction from the F-N-R lever unit 30 over an instruction from the F-N-R switch unit 40, and a selector switch 41 which by an operation of a switching control member 41a, instructs the controller 42 to switch to the second control state or to cancel the second control state. As a consequence, the system has made it possible to return to the first control state without an operation of the first forward/reverse control means.

    摘要: The present invention provides a construction machine adopting a structure that assures a predetermined sound pressure level along a forward direction relative to the construction machine and allows a warning horn to be miniaturized. Warning horns 12 and 13 are mounted in the vicinity of at least either a left headlamp 9 or a right headlamp 10 provided on the left side and the right side of a vehicle body 3 of the construction machine. The warning horns 12 and 13 are housed inside a bracket 11 used to mount the headlamp 9 or 10. The plurality of warning horns 12 and 13 are disposed on a single side toward the left headlamp 9 or the right headlamp 10. Since a front attachment 7 does not block the sound generated from the warning horns 12 and 13 and thus the warning sound can travel without hindrance along the forward direction, a predetermined sound pressure level is achieved with ease along the forward direction relative to the vehicle body 3.
