This is a Technical Specification document for a 1/2 ton capacity air hoist (JML DOC: 53290158) required by the U.S. Department of Defense. The air hoist must comply with ASME HST-5-1999 standards and ASME B30.16, with non-conformance resulting in rejection. The hoist requires permanent OEM identification marking and WLL (Working Load Limit) designation with a minimum safety factor of 5. Key performance requirements include: 1,100 lb lifting capacity, 7 MM x 21 MM chain dimension, 60-foot rope controls, body dimensions of 17.7 inches hook-to-hook and maximum 6.9-inch width, and top and bottom swivel hooks. The unit must be suitable for hazardous and food industry environments, withstand shock loads without component failure, and operate in extreme industrial conditions resistant to dust, vapors, and humidity.

Additional specifications mandate ISO 9002 QA certification, offshore paint finish (four coats with epoxy primer and two top coats), asbestos-free brakes, pneumatic operation at 85 PSI with capability to withstand pressure increases up to 130 PSI, and oil-free permanent internal motor lubrication. The air hoist must be rated for 100% duty cycle with unlimited starts/stops per hour, operate across a temperature range of negative 4°F to 158°F, achieve noise levels not exceeding 80 dB(A), and accommodate horizontal pulling and lateral drifting applications. Alternative makes and models require C/702 concurrence before contract award, and replacement parts with complete assembly and parts lists must be readily available per ASME HST-5-1999 A2.8.
