Abstract:
PROBLEM TO BE SOLVED: To provide an industrial vehicle in which revolutions of a hydrostatic pump (HST) motor are prevented from exceeding allowable revolutions. SOLUTION: An industrial vehicle is provided with a speed sensor 21 for detecting revolutions of the axle, and a controller 31 for decreasing the revolutions of a HST motor by driving an inching solenoid valve 11 when it is detected that revolutions of an HST motor exceed allowable revolutions on the basis of revolutions of the axle, for judging whether the revolutions of the HST motor exceed the allowable revolutions or not when downshift is performed by a transmission operating switch 32, and for performing downshift after decreasing the revolutions of the HST motor after locking downshift when it is judged that the revolutions of the HST motor exceed the allowable revolutions. Therefore, the revolutions of the HST motor can be prevented from exceeding the allowable revolutions, and the HST motor can be prevented from being abnormal.
