Industrial vehicle
An industrial vehicle includes an engine, a hydraulic pump, a hydraulic operation device, a supply passage, a drainage passage, an unloading valve that connects the supply passage and the drainage passage to each other, and a controller that controls open/closed state of the unloading valve. If an on-load period at the time of application of load on the engine is less than a first predetermined time, the controller performs open/close control of causing the unloading valve to enter the closed state to set an on-load state, thereby increasing pressure of hydraulic oil passing through the supply passage and then causing the unloading valve to enter the open state.
