JXHK-GB-1219 is a high-pressure hydraulic ground power cart engineered for aerospace ground support operations, rated at 3500 psi and compliant with AS9100D aerospace quality standards, specifically designed for powering hydraulic systems of wide-body aircraft like Boeing 777 and Airbus A330 during MRO procedures.

Constructed with a heavy-gauge steel frame coated in anti-corrosive epoxy and a stainless-steel hydraulic reservoir, it features a 45kW diesel engine driving a positive-displacement pump, delivering a flow rate of 25 L/min. Weighing 2,800 kg with a 3.2m×1.8m footprint, it operates at -30°C to 110°C and includes a pressure relief valve set at 3800 psi for safety. This cart supplies hydraulic power for landing gear retraction tests, flap actuation checks, and brake system maintenance, adhering to FAA Part 139 and EASA Ground Operations regulations.
