本设备推荐规程规定了永久性车载或滑入式附属装置的要求，该装置设计用于将集料除冰、防冰或摩擦改性固体材料或湿固体材料运输和分配到跑道、滑行道、坡道、航站区和机场其他铺面上。它不适用于ARP5559中规定的液体物料撒布机。物料撒布机可永久安装在运输车、拖车或半拖车上，或临时安装在运输车辆拖车或半挂车上，仅用于季节性使用。运输车可仅用于材料摊铺应用，或提供其他功能，如犁车、平板或倾卸体。运载工具是自行的- 推进式原动机，通常是一种商用或专门制造的卡车，提供在这些铺筑路面上移动材料撒布机的机动性。ARP5943犁和ARP5539（带载具的旋转犁）中提供了载具推荐实践。本推荐规程不包括运载车、扫雪机或运载车的其他应用的要求。 机场赞助商需要该设备，以便在冰雪活动之前、期间和之后维护机场。与其他配套的除雪设备（SRE）相结合，材料撒布器将使机场能够在积雪或结冰之前改变飞机使用的表面上的摩擦力；雪或冰事件期间或之后；或者在通过其它除雪设备除雪或除冰之后。 物料撒布车通常配备有位移犁，以提供犁耕和物料撒布功能。一些装置可用于其他服务，例如停车场或道路雪和冰控制、用于溢出的材料、用作常规自卸车或其他应用。 本文件的目的是描述一种料斗式物料撒布器，或料斗式物料布料器与用于预润湿化学品的储液罐相结合，配有后端撒布装置和必要的操作控制装置，适用于机场应用的运输车辆上的撬装或底盘安装。撒布器材料沉积由单个操作员控制，通常由运载车辆的驾驶员控制，使用一个控制面板方便地放置在靠近驾驶员位置的操作员控制站附近。 物料撒布器主要由料斗的承载能力（通常以立方码表示）和可靠准确的物料撒布路径宽度（通常以英尺表示）确定。目前，典型的料斗容量从约8立方码到约16立方码不等；扩展宽度从大约12英尺到大约80英尺不等。材料摊铺模式应产生均匀的分布模式，在整个摊铺速度范围内，从2英尺宽到最大规定摊铺宽度的均匀路径。该装置的设计应允许使用斗式装载机、固定设备和手动装载。它应能保护料斗中的干燥材料不直接暴露在空气中，尤其是雪前、雪中和雪后的水分，以及材料在机场表面上的安全和一致传播。 此外，当不再需要（风暴/季节结束）或机组维护时，机组必须提供有效地从料斗中移除材料的方法。 材料撒布机的设计应适用于使用任何典型的机场雪和冰控制化学品，特别是机场沙、乙酸钠、氯化钙、甲酸钠尿素和尿素液体溶液以及液体乙酸钾。机场赞助商可指定适合其运营需要的其他化学品。

This equipment recommended practice defines the requirements for a permanent vehicle-mounted or slip-in accessory device designed to transport and distribute aggregate de-icing, anti-icing, or friction modifying solid materials or wetted solid materials onto runways, taxiways, ramp, and terminal areas and other paved surfaces on an airport. It is not intended for liquid material spreaders which are addressed in ARP5559. The material spreader may be permanently mounted on a carrier vehicle, trailer, or semi-trailer, or temporarily installed on a carrier vehicle trailer, or semi-trailer for seasonal use only. The carrier vehicle may be dedicated to material spreading applications only, or provide additional functions such as a plow vehicle, flat bed or dump body. Carrier vehicles are self-propelled prime movers, generally a commercial or purpose-built truck that provides the mobility to move the material spreader on these paved surfaces. Carrier vehicle recommended practices may be found in ARP5943 plows and ARP5539, rotary plow with carrier vehicle. This recommended practice does not include requirements for the carrier vehicle, snow plow or other applications for the carrier vehicle. The airport sponsor requires this equipment in order to maintain the airfield prior to, during and after snow and ice events. In combination with other supporting Snow Removal Equipment (SRE), the material spreader will enable the airport to modify the friction on surfaces used by aircraft prior to the accumulation of snow or ice; during or after a snow or ice event; or, after the removal of snow or ice by other snow removal equipment. Material spreader vehicles are often equipped with a displacement plow to provide both plowing and material spreading functionality. Some units may be used for other service such as parking lot or roadway snow and ice control, applying material for spills, for use as a conventional dump truck, or other applications. It is the intent of this document to describe a hopper type material spreader, or hopper type material spreader combined with a liquid reservoir for pre-wetting the chemical, complete with rear end spreading device and necessary operational controls, suitable for skid mounting or chassis mounting on a carrier vehicle for airport application. The spreader material deposition is controlled by a single operator, normally the driver of the carrier vehicle, employing a control panel conveniently placed near the operator control station close to the driver’s position. Material spreaders are primarily defined by the carrying capacity of the hopper (typically expressed in cubic yards) and by the width of the path for reliable and accurate material spreading (typically expressed in feet). Presently, typical hopper capacities vary from about 8 cubic yards to about 16 cubic yards; and, spreading widths vary from about 12 feet to about 80 feet. The material spreading pattern should produce a uniform distribution pattern, an even path from as little as 2 feet wide to the maximum specified spreading width throughout the spreading speed range. The unit should be designed to allow loading with bucket loaders, fixed equipment and manual loading. It should provide for protecting the dry materials in the hopper from direct exposure to the elements, particularly moisture before, during and after a snow event, and the safe and consistent spreading of the material on airport surfaces. In addition, the unit must provide methods of efficiently removing material from the hopper when no longer needed (end of storm/season) or for unit maintenance. Material spreaders should be designed for operation using any of the typical airport snow and ice control chemicals, specifically including airport sand, sodium acetate, calcium chloride, Sodium Formate Urea and Urea liquid solution and liquid Potassium Acetate. Airport sponsors may specify other chemicals appropriate to their operational needs.
