  • Patent number: 11208023
    Abstract: A Trailer Loading/Unloading System may comprise a tilting flatbed trailer having one or more push bars configured to move along the surface of the trailer bed 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 push bars 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. These two chains may loop around a rear guide shaft at the rear of the trail and a front guide bar shaft at the front of the trailer. The guide shafts may be secured beneath the surface of the trailer, and may include sprockets around which the chains loop. A motor, e.g., a winch, may be secured to the trailer and may drive, using a sprocket and chain running around a shaft protruding from the motor, one of the guide shafts, e.g., the front shaft, by turning a sprocket mechanically secured to the front guide shaft.

  • Publication number: 20210354614
    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.
