The Air Force Packaging Technology Engineering Facility AFPTEF was tasked to perform qualification testing of a shipping cradle, in support of Air Mobility Command and Dover TMF. Testing was performed in accordance with ASTM D4169, Distribution Cycle 18, for level B packaging assurance level II. AFPTEF found that the initial cradle design prevented the tirewheel assembly from rolling forward-aft motion however, reinforcement of the cradle was necessary to prevent side-to-side movement of the item during testing. During the forklift truck handling portion of testing, the item broke loose in the cradle, snapping one of the side-support beams. AFPTEF added diagonal framing and side block reinforcements, in addition to thicker side-support beams to prevent side-to-side motion of the item during shipment. The modified cradle design passed all testing. |
