A boom pivotably supported on a vehicle body, a bucket pivotably supported on a tip end of the boom, a lift cylinder 118 which drives the boom, an accumulator 117 connected to the lift cylinder 118 through a branched oil passage 146a, a switching valve 115a connected to the branched oil passage 146a between the lift cylinder 118 and the accumulator 117 to switch between a connected state and a disconnected state between the lift cylinder 118 and the accumulator 117, and a controller 111 which performs switch control of the switching valve 115a are provided. The controller 111 is provided with a state detecting unit which detects whether the bucket is in a loaded state, and a switching valve control unit which switches the switching valve 115a to the connected state when the state detecting unit detects that the bucket is in the loaded state. According to this, it is possible to realize decrease in falling of a loaded burden and improvement in riding quality together with efficient use of force generated by a hydraulic pump 141. |
