Abstract:
1. A work vehicle comprising: a pair of booms attached to a front part of a vehicle body in an upwardly and downwardly rotatable state; a parallel link motion mechanism coupling a working unit to tips of the booms, the parallel link motion mechanism keeping the working unit in a posture generally parallel to the ground without rotating the working unit with respect to the ground while the booms are elevated from a position where the working unit is disposed on the ground when the working unit is a fork; and a control unit monitoring an angle of the booms and a tilt angle of the working unit; the control unit executing a tilt angle adjusting control of the working unit in accordance with variation in the angle of the booms while the booms are elevated from the position where the working unit is disposed on the ground when the tilt angle of the working unit is greater than or equal to a predetermined threshold; and the control unit not executing the tilt angle adjusting control when the working unit is a fork such that the parallel posture of the working unit is maintained by the parallel link motion mechanism.
