A hydraulic controller (30) for an industrial vehicle (10) includes a hydraulic pump (31) configured to pump hydraulic oil, an actuator (21, 24), a hydraulic oil passage that connects the hydraulic pump (31) and the actuator (21, 24), and a control valve (37) configured to control a flow direction of the hydraulic oil. The hydraulic controller (30) further includes a position detector (27) configured to detect a position of an operation lever (25), a key switch (29), an unloading switching valve (54) that is configured to return the hydraulic oil to a tank (35), and a controller (28). The controller (28) sets the unloading switching valve (54) to an open state when the key switch (29) is turned ON, and sets the unloading switching valve (54) to a closed state when the position detector (27) indicates that the operation lever (25) is in a neutral position.
