Wheel Assembly, Pneumatic

This Special Packaging Instruction (SPI) outlines detailed requirements for the packaging, handling, and shipping of Tire & Wheel Assemblies (T&WA), including new, repaired, and unserviceable items. The document emphasizes safety precautions during inflation/deflation, specifying the use of OSHA-approved safety cages and maintaining a safe distance. It provides comprehensive guidelines for packaging, including horizontal or vertical orientation on pallets, use of separators (fiberboard or polyethylene foam), and specific pallet types (ASME MH1 compliant). The SPI details materials for containers and wraps, such as fiberboard-lined wood containers and specific types of polyethylene shrink/stretch wrap. Additionally, it specifies marking requirements for different packing levels and types of assemblies, including warnings for split rims and shelf-life information. This instruction aims to prevent damage to T&WA during transit and storage while ensuring personnel safety and compliance with military and international dangerous goods regulations (IATA DGR).
