A conveyor system for loading pallets into and out of a vehicle comprises an accumulating conveyor and an airbag rail. The accumulating conveyor is constituted by a pair of chain rails for supporting and conveying pallets into and out of a vehicle. The airbag rail is positioned between the chain rails and adjacent to one of the chain rails. The airbag rail is constituted by a base beam, a lift beam and an airbag positioned between the two beams. The arrangement is such that, with the chain rails and the base beam fixed to the floor of a vehicle, the airbag can be inflated to raise the lift beam so as to lift an edge portion of a pallet supported by the two chain rails out of contact with said one chain rail.

An improved cargo dolly has at least two top rail assemblies and a frame with an inner rail having mounting brackets for receiving the top rail assemblies. Each top rail assembly spans the width of the frame but not the length of the frame and can move between an attached state and an unattached state by actuating fasteners that pass through the top rail assembly to its respective mounting brackets on the frame. The movement between the attached and unattached states occurs independently of an attached or unattached state of the other top rail assembly.

A battery transfer apparatus for loading/unloading batteries from materials handling vehicles includes a mobile unit and a battery stand. The mobile unit is used to transport batteries into/out of materials handling vehicles and includes load handling structure comprising at least one roller, which is used to roll batteries into/out of materials handling vehicles. A top wall of the battery stand includes at least one opening and support structure of the battery stand engages a surface so as to support the battery stand thereon. The battery stand is engaged by the mobile unit during battery transfer operations by inserting the roller(s) up through the opening(s) in the top wall of the battery stand such that the roller(s) can engage the battery through the opening(s). The battery stand is capable of storing the battery while the battery is out of the materials handling vehicle.

A vehicle insert with refrigerated and non refrigerated sections for facilitating product distribution is described which uses a pair of frames defining a vertical member and one or more horizontal members. Several shelves with rollers are attached to the frames. The shelves define a sloped area wherein the lowest point on the shelves is located at a product retrieval point and wherein said insert is wheeled into a vehicle already loaded with product to be delivered.

Loading and unloading apparatus for a refrigerated trailer including a floor with a plurality of ribs extending longitudinally along the floor of the refrigerated trailer with a gap between adjacently disposed ribs, a sub floor disposed over the floor and the longitudinally extending ribs; a plurality of roller tracks disposed on the sub floor, the roller tracks extending longitudinally in the trailer and spaced apart from each other and a plurality of sleepers, the sleepers disposed longitudinally in the trailer and generally parallel with the roller tracks, with at least one of the plurality of sleepers disposed between adjacently disposed roller tracks. Preferably, a refrigeration unit has bifurcated ducts located along the ceiling adjacent to the sidewalls to preserve ceiling height.

A system and a method for loading, transporting and unloading large, heavy field equipment to and from nontraditional operational location. The invention discloses a specially designed tilt flatbed trailer, a winch and cabling mounted near the front of the trailer bed, and heavy duty steel rollers imbedded into the flatbed surface. Initially, the trailer is positioned in an upwardly titled angle such that the rear edge of the trailer bed is near ground level next to the lead edge of the equipment. The winch cabling is attached to the equipment and pulls it over the rear edge of the trailer via a larger receiving roller. The equipment is pulled upward and onto the trailer bed until the rear edge of the equipment base clears the ground. The tilt bed is then lowered to a horizontal position. During loading, the equipment moves smoothly onto the trailer surface via the embedded rollers. To unload, the process is reversed.
