A hydraulic excavator includes a controller and an instruction switch for selectively instructing three kinds of work modes. The controller includes a target rpm storage unit, a target rpm computer for selecting one of stored upper limits of the target rpm according to an instruction by an instruction switch and computing a target rpm in a range smaller than the selected upper limit, and a communication unit.

When the work mode is instructed from the server, the target rpm computer computes a target rpm based on the instructed work mode.

Abstract: A display system for a working machine displays warning information while also displaying a high-quality camera image. The display redisplays a reduced camera image at a reduction scale of 60% according to an abnormality information signal. An open area 44 outside the area displaying the camera image. The display control device displays a warning icon (large size), corresponding to abnormality information regarding a filter of a DPF device, in the open area. The operator recognizes the warning and immediately stops the operation, moves to a place where the filter regeneration is possible while checking the safety of the surroundings by viewing the camera image, and then carries out the filter regeneration. After finishing, the operator confirms that the warning icon has disappeared, moves to the site of the operation while checking the safety of the surroundings by viewing the camera image (for normal times), and then restarts the operation.

Abstract: A display system for a working machine displays basic information at all times and, in case of an abnormality, displays the details of the warning in addition to the basic information to enable an operator to reliably recognize details of the warning. For example, a first warning display function, upon receiving an abnormality information signal relating to a charge warning, displays an appropriate warning icon in a warning icon display region. A simplified basic-information display function, then displays simplified basic-information images and a second warning display function displays, in a free area of the display, a second warning message inclusive of a “Charge warning” message as display details of the warning icon, and of character information relating to a simplified remedial action. The operator can then reliably recognize the “Charge warning” and understand its details as well, by viewing the second warning message in addition to the warning icon.

Abstract: An exhaust purification system for a working machine reliably issues filter regeneration warnings to the operator, prompting manual regeneration, so that damage to the DPF device can be avoided. When a PM estimate becomes higher than a given value, a screen displays a warning message prompting manual regeneration. If the warning message fails to prompt the operator to perform manual regeneration and reference time t1 has passed since the display of the warning message, a speaker outputs a first warning sound. When the operator notices the first warning sound and turns on a regeneration switch, regeneration control is started. If the operator fails to notice the first warning sound and reference time t2 passes, the speaker instead outputs a second warning sound louder than the first warning sound. When the operator notices the second warning sound and turns on the regeneration switch, regeneration control is started.
