本SAE航空航天推荐规程（ARP）规定了飞机单元载荷装置地面和终端装卸设备的要求，这些设备将直接影响装置的使用寿命，以防止装置过度磨损。过去的经验表明，上述设备的运行缺陷会导致设备成本高。需要加强对维护的控制。本文件中包括对卡车、运输机、推车、存储设备、托盘制造上使用的输送机系统、导轨、挡块、复位硬件的要求- 提升机或其他ULD处理设备。这些要求反映了应用于已知成功运行硬件的最先进标准。应要求任何设计偏差证明与本规范标准等效。这些ULD通常构成飞机不可分割的一部分，因此受监管机构要求的约束，以确保结构完整性。本文件不包括ULD的尺寸、形状和承载能力。这些可从SAE或IATA规范、航空公司运营商和ULD制造商处获得。

This SAE Aerospace Recommended Practice (ARP) specifies requirements for those portions of the aircraft unit load device ground and terminal handling equipment that will have a direct bearing on the life of the device for the purpose of preventing undue wear on the device. Past experience has shown that in-service defects in regard to the above equipment cause high devices cost. Greater control of maintenance is required.Included in this document are requirements for conveyor systems, guides, stops, resitraint hardware that are used on trucks, transporters, dollies, storage provisions, pallet build-up hoists, or other ULD-handling equipment.These requirements reflect state of the art criteria applied to known successfully operated hardware. Any design deviations shall be required to demonstrate equivalency to this specification criteria.These ULD's usually form an integral part of the aircraft and as such are subject to regulatory agencies' requirements to assure structural intgrity.Size, shape and load capacities for ULD's are not included in this document. These can be obtained from SAE or IATA speciications, the airline operator and the ULD manufacturer.
