Aircraft catering carts are specialized ground support equipment used at domestic civil airports to deliver meals to aircraft. These carts utilize hydraulic lifting systems to adjust working heights, adapting to the door positions of different aircraft models. Their compartments are equipped with securing devices to ensure stability during meal transport. In 2017, the Civil Aviation Administration of China (CAAC) issued the industry standard “Aircraft Catering Cart” (MH/T 6016—2017), specifying technical requirements and safety performance metrics for the equipment. Multiple domestically produced aircraft catering cart models have been successfully delivered and exported overseas, marking a significant technological breakthrough in the application of ground support equipment within the civil aviation sector.
