Abstract:
To provide an industrial vehicle capable of reducing cavitation without using detection means for detecting a stop of a cargo handling tool in descent of the cargo handling tool.
An anti-cavitation check valve 47 is connected in parallel to a hydraulic pump 40 in a pipe line of hydraulic oil. A main control unit 51 and a motor driver 50 control a torque of a motor 42 for lift so that the motor 42 rotates at a target revolution speed according to an operation amount of a cargo handling lever as well as a torque restriction is applied in regeneration in which the hydraulic oil of a cylinder 16 is returned in association with a descent operation of a fork.
