[0003] As a frequently used civil aircraft, the Xianzhou-60 aircraft often flies back and forth between airports across the country for flight missions. However, when it lands at a foreign airport for maintenance, the QYC-1 hydraulic oil refueling vehicle that comes with it can add hydraulic oil to the aircraft on the ground, but it is not very convenient in actual use. Due to its large size (890mm*610mm*870mm), the equipment cannot be installed for transportation, and it is inconvenient to carry when the aircraft is transferred to another location. At the same time, the equipment needs to be connected to an external 220V AC power supply when used in the field, which has high requirements for airport security conditions. Most airport field security conditions do not meet this requirement. Utility Model Content
