  • Publication number: 20210301498
    Abstract: A work machine includes an elevating cab and processing circuitry. The processing circuitry is configured to detect the position of the elevating cab and to maintain a travel speed at low speed when a traveling operation is performed while the detected position of the elevating cab is higher than a predetermined height.

  • Patent number: 10106955
    Abstract: A turning control apparatus includes a turning body and a hydraulic motor to turn the turning body. A high-pressure relief circuit relieves hydraulic pressure of a first hydraulic line at a first relief pressure, the first hydraulic line supplying an operating oil to drive the hydraulic motor. A hunting reduction circuit relieves a hydraulic pressure of a second hydraulic line at a pressure lower than the first relief pressure, the second hydraulic line being connected to a deceleration-side hydraulic port from which the operating oil is discharged when the hydraulic motor is being driven. The hunting reduction circuit connected to the deceleration-side hydraulic port is caused to open before an operation lever to operate turning of the turning body returns to a neutral position.

  • Publication number: 20150000974
    Abstract: A routing structure of a wire harness is continuously routed by being bent upward from two ends of an under-floor routed area under a floor of an automobile body, and being drawn out, at least on the rear side, to above the floor through a through-hole formed in a floor panel of the automobile body, wherein the wire harness is inserted into a continuous metal pipe, the metal pipe is bent upward at a location where the metal pipe is inserted into the through-hole of the floor panel, the metal pipe into which the wire harness is inserted is routed through the through-hole, a grommet is externally fitted on and fixed to a region of the metal pipe that is inserted into the through-hole, and a seal lip provided on the grommet is pressed against the lower surface of the floor panel from the underfloor side to block water.
