Beschreibung
Zusammenfassung:	An industrial vehicle includes a hydraulically-operated brake device, a hydraulically-operated loading device, an electric motor, a hydraulic pump, a first hydraulic circuit having an accumulator and a detector for detecting pressure accumulated in the accumulator, a first oil passage connecting the first hydraulic circuit and the hydraulic pump, a load handling device, a second hydraulic circuit having a closed center control valve, a second oil passage connecting the second hydraulic circuit and the hydraulic pump, an oil tank, a pressure compensating circuit, a pilot passage, and a controller. When a selector valve is placed in a first position, hydraulic pressure generated by the hydraulic pump is transmitted to a pressure compensating valve in such a direction that disconnects the hydraulic pump from the oil tank to thereby create in the first oil passage hydraulic pressure that causes the accumulator pressure accumulation.
