  • Patent number: 10876270
    Abstract: A wheel loader includes: an operating state detecting unit detecting an operating state; a target setting unit setting a relationship between a target position of a working equipment and a travel distance of the wheel loader for the operating state detected by the operating state detecting unit; a travel distance detecting unit detecting the travel distance of the wheel loader; and a working equipment controlling unit moving a boom and a bucket to the target position of the working equipment determined depending on the travel distance detected by the travel distance detecting unit.
    Type: Grant

  • Patent number: 9650760
    Abstract: A control device of a wheel loader obtains a first ratio between a value corresponding to a target traveling distance for the wheel loader, when it travels to a discharge position where an excavated substance is discharged after an excavation with a bucket, and a value corresponding to a target elevation amount for an elevation of a boom after a motion is started. The control device also obtains a second ratio between a value corresponding to an actual traveling distance after the wheel loader starts its motion to the position where the excavated substance is discharged after the excavation with the bucket, and a value corresponding to an actual elevation amount of the boom after the motion is started. The control device then controls a transmission toque transmitted to a drive wheel from an engine in order that a difference between the first ratio and the second ratio becomes zero.
