Abstract
A Trailer Loading/Unloading System may comprise a tilting flatbed trailer having one or more cross-supports and/or push bars configured to move along the surface of the trailer bed to push palletized cargo off the trailer, move palletized cargo back and forth on the trailer, and prevent rapid descent or undesirable slipping of palletized cargo. Each of the cross-supports may be secured between a chain on the left side of the trailer bed and a chain on the right side of the trailer bed. In one embodiment, the cross-supports may be sufficiently close to place a pallet or other item on top of the cross-supports. In an additional embodiment, a belting loop may cover the cross-supports, thereby allowing for handling of loose material, e.g., gravel, rocks, or soil.
