Design – the c-17 mlg post shipping and storage container (cnu-677/e) design meets all the users’ requirements. The cnu-677/e is a sealed, welded aluminum, controlled breathing, reusable container. The container is engineered for the physical and environmental protection of the post during worldwide transportation and storage. The container consists of a base and completely removable cover equipped with the special features listed below. The base is a one piece skid/double walled base extrusion with forklift openings, humidity indicator, pressure equalizing valve (1.0 psi pressure/ 1.0 psi vacuum) and desiccant port for easy replacement of desiccant (controls dehumidification). A silicone rubber gasket and quick release cam-over-center latches create a water/air-tight seal at the base-cover interface. Container external dimensions are 77.8 inches length, 62.1 inches width, and 36.9 inches height. Container empty weight is 578 pounds, and 1323 pounds with the post in place. An aluminum cradle system is integrated into the base design that rigidly mounts the post to the container base . The post is attached to the cradle system with three large silicone-lined aluminum clamps with quick release handles that make loading and unloading easy and safe. There are no detachable parts on the container other than the container lid, which eliminates FOD risks.
