  • Publication number: 20240102261
    Abstract: A boom cylinder drives a boom, and includes a head side oil chamber and a bottom side oil chamber. A first valve includes a first opening for discharging oil in the head side oil chamber to an oil tank, and supplies oil from a hydraulic pump to the head side oil chamber. A second valve includes a second opening for discharging oil in the bottom side oil chamber to the oil tank, and supplies oil from the hydraulic pump to the bottom side oil chamber. A controller individually controls an opening degree of the first opening and an opening degree of the second opening, during work including manipulation of the boom.

  • Patent number: 9856625
    Abstract: A working vehicle includes: a vehicle body; and a boom; a bucket; a boom driving unit including a boom cylinder; a bucket driving unit configured to swing the bucket; a boom-bottom pressure sensor configured to detect a boom-bottom pressure of the boom cylinder; and a working equipment controller configured to control at least one of a lift motion of the boom and a tilt motion of the bucket. The bucket includes an inclined portion. The working equipment controller controls the lift motion or the tilt motion by comparing a threshold set in accordance with an inclination angle of the inclined portion with the boom-bottom pressure.
