Abstract
A control deviceof an industrial vehicle which performs the control of actuating a parking brakeduring operator's absence in an industrial vehicle includes a seat switch, a vehicle speed sensor, and the parking brakecontrolled by a parking brake solenoid, and a counterwhich counts the elapsed time after the seat switchdetects the operator's absence. The control device sets the time corresponding to the time until the operator leaves the vehicle after the operator leaves the seat as a preset absence time. When the seat switchhas detected absence, a control signal which validates the parking brakeis output to the parking brake solenoid, thereby actuating the parking brakeif the vehicle speed shows a vehicle stopped state, and the elapsed time becomes equal to or more than the set absence time.
