  • Patent number: 11951815
    Abstract: A wheel loader as a work vehicle includes a ladder, an operator's compartment, an actuator, an operation unit, and a controller. The operator's compartment has an openable and closable door disposed above the ladder. The actuator is disposed at the operator's compartment so as to actuate the door to make an opening motion. The operation unit receives an operation from an operator. The controller controls the drive of the actuator, based on an operation signal received from the operation unit, so that the door makes an opening motion while the operation unit is receiving an operation from the operator.

  • Patent number: 10378183
    Abstract: A wheel loader comprises a console box and a support component. The console box is disposed on the side of an operator's seat and is able to rotate in the forward and backward direction. The support component has a rotary shaft disposed in the left and right direction under the console box, and rotatably supports the console box around the rotary shaft between an operation position in which the console box is disposed horizontally and a retracted position in which the console box is rotated rearward from the operation position and is disposed at an angle. The location of the center of gravity of the console box is disposed more to the front than the rotary shaft at the operation position, and more to the rear than the rotary shaft at the retracted position.

  • Patent number: 10370821
    Abstract: A work vehicle includes a console box disposed to a side of an operator's seat, and a support including a rotational axis disposed in a left and right direction below the console box. The console box is configured to be rotatable in a forth and back direction. The support rotatably supports the console box around the rotational axis and between an operating position in which the console box is horizontally disposed and a retracted position in which the console box is inclined at a position in which the console box has been rotated rearward from the operating position. A spacing in a horizontal direction between front and rear ends of the console box disposed in the retracted position is less than a spacing in the horizontal direction between front and rear ends of the console box disposed in the operating position.

  • Patent number: 10196795
    Abstract: A wheel loader includes a console box, a link rod, and a shutoff valve. The console box is disposed on the side of an operator's seat, is able to rotate in the forward and backward direction between an operation position in which the console box is disposed horizontally and a retracted position in which the console box is rotated rearward from the operation position, and has a slot. The link rod is connected at one end to the slot and transmits the rotation of the console box. The link rod is able to rotate a shaft to switch between an open position in which an actuator drive-use hydraulic circuit can be actuated, and a closed position in which the actuator drive-use hydraulic circuit cannot be actuated. A second end of the link rod is linked to the shaft.
