An industrial vehicle includes a hydraulic brake device, a hydraulic load handling device, a first hydraulic circuit, a second hydraulic circuit, a pressure compensating circuit, and a controller. The controller sets an electromagnetic valve to a first position during operation of the load handling device. The controller sets the electromagnetic valve to a second position and controls an electric motor to drive a hydraulic pump when determining that pressure needs to be accumulated in a hydraulic accumulator based on a detection result of a detector. When the electromagnetic valve is at the second position, hydraulic pressure generated by driving the hydraulic pump is applied to a pressure compensating valve and produces a force acting in a direction to disconnect the hydraulic pump and an oil tank from each other, so that hydraulic pressure is generated in a first oil passage to be accumulated in the hydraulic accumulator.
