油圧取出手段。 A hydraulic pump is used in an aerial work vehicle configured to supply a specified amount of hydraulic oil to the hydraulically operated equipment mounted on the tip of the boom, etc., and the lower hydraulically operated equipment mounted on the chassis, etc., to operate both hydraulically operated equipment. By interposing an electromagnetic valve in the oil supply pipe connected to the boom, a predetermined hydraulic oil is sent to the hydraulically operated equipment mounted on the tip of the boom, etc. and the lower hydraulically operated equipment mounted on the vehicle chassis, etc., and the lower hydraulic A priority valve is connected to the oil supply pipe of the operating equipment, and when the priority valve is operated, a part of the hydraulic oil sent to the lower hydraulic operating equipment is diverted to the hydraulic operating equipment installed at the tip of the boom, etc. A lower hydraulic pressure extraction means in an aerial work vehicle, characterized by:
