Included are forks 3, cylinders 4 for causing the forks 3 to perform an ascending/descending operation in accordance with the flow rate of hydraulic oil, a first valve 5 for controlling the flow rate of hydraulic oil in accordance with an energizing current, a second valve 6 for regulating the flow rate of hydraulic oil in accordance with cylinder pressure, and a control portion 7. The control portion 7 calculates the flow rate to be regulated by the second valve 6, on the basis of cylinder pressure detected by a pressure sensor 9, calculates a current command value for the energizing current, with the flow rate to be controlled by the first valve 5 being set equal to the regulated flow rate, and changes the energizing current in two stages, with the current command value as the upper limit of the energizing current, thereby decelerating the forks 3 in two stages when stopping the ascending/descending operation.
