Claim Text:
1. An industrial vehicle comprising: an engine; a hydraulic actuator; a hydraulic pump driven by the engine; an instruction member, including a tilt operation member or a lift operation member or both the tilt operation member and the lift operation member, wherein the instruction member operates the hydraulic actuator; a supply passage adapted to supply hydraulic oil discharged from the hydraulic pump to the hydraulic actuator; a return passage adapted to return the hydraulic oil discharged from the hydraulic pump to an oil tank; and a controller adapted to compare an engine speed and a predetermined comparison threshold value, wherein the controller is adapted so that when the engine speed is less than the comparison threshold value, the controller opens the return passage so that the hydraulic oil flows through the return passage, wherein the comparison threshold value includes a first threshold value and a second threshold value that is lower than the first threshold value, and the controller is adapted to, in response to the operation of the instruction member, open the return passage so that the hydraulic oil flows through the return passage, perform revving control to increase the engine speed, and change the comparison threshold value from the first threshold value to the second threshold value.
