A hydraulic system for a forklift includes a handle angle sensor for outputting a rotational angle signal indicative of a rotational angle of a handle, a wheel angle sensor for outputting a wheel angle signal indicative of a steering angle of wheels, and a controller. The controller calculates a rotation angular velocity of the handle based on the rotational angle signal from the handle angle sensor to discharge from the hydraulic pump the hydraulic fluid of a flow rate in conformity with this rotation angular velocity, and controls the flow rate of the hydraulic fluid supplied to the power steering cylinder based on the rotational angle signal from the handle angle sensor and the wheel angle signal from the wheel angle sensor to steer the wheels in conformity with the rotational angle of the handle.
