These are two of our standard loads that we move daily. In the foreground are tri-walls that are basically collapsible cardboard boxes with plastic tops and bottoms. The Marines use them a lot since they fit in all their aircraft and they slide easily across the floors. We can carry 12 at a time but the problems arise when they load them up. We have had some over 2000lbs and they fall apart when we try to move them (not to mention the strain on the crewmembers). In the background is a 463L pallet (with 4 tri-walls on it). They work really slick with our rollers installed and we used them all the time on our last rotation. These are the same ones the Air Force use so they can take the cargo directly from the airplane to the helicopter. The problem is none of the Marine helicopters are wide enough so they don't use them at all. It has been a slow process but we are getting the Marines to use them more and more when our unit gets the mission. They are by far the best way to move heavy loads. We can load up to 7000lbs per pallet and even with that much weight they slide easily on the rollers.
