Abstract:

The van body tie-down test was performed on a smooth, level, concrete slab containing a fixed group of permanent anchors set in the concrete, each equipped with a heavy attaching ring. The four anchors used in the test agree closely with the sparing of tie-down rings in the C-124 aircraft. For the lifting test, sling cables were attached at each end of a longitudinal spreader bar directly over the lifting eyes. Gradually increasing equal pressure was applied through hydraulic actuators. The van floor was loaded with successively greater weights, to simulate 2.0Gs. Subsequently, the body sides were opened to full expanded position, and then re-closed. These operations proceeded smoothly, with no evidence of binding.
