Abstract

A cargo transportation system comprising secure (fully closeable and lockable), sealable, stackable, trackable, universal, auto-latching “pallet boxes” that may be used in two main ways: 1) secured to the undercarriage transverse I-beams of over-the-road semi-trailers by means of loading alignment and hanger assemblies that provide positive locking-in-place; and 2) stackable, up to three or more high, inside the trailer bodies. The inventive pallet boxes are designed to be secured by auto-latching hanger assemblies that are retrofittable on individual types of semi-trailer undercarriages, both US and metric (European, Central and South American, and Asian) standard dimensions. The pallet boxes include vertical sidewall load-bearing channel members permitting stacking fully-loaded pallet boxes three or more high. The pallet boxes may be refrigerated, insulated, or atmospherically controlled, e.g., chargeable with preservative, security or disinfecting gases, during shipping.

Claims

1. Alignment and hanger assembly for underslung transport of containers by truck trailers comprising in operative combination:

i) a pair of spaced vertically orientable guide panels having horizontal flanges for engaging selected bottom flanges of I-beams of a wailer undercarriage;

j) at least one cross-brace joining said guide panels in preselected spaced relationship, said cross brace providing a stop for said container during positioning under said truck undercarriage;

k) at least one clamp member for each of said guide panels to secure said guide panel to a selected trailer undercarriage I-beam inboard of a side of said trailer body;

l) a pair of spaced, vertically orientable support panels securable to said selected bottom flanges of I-beams of a trailer undercarriage outboard of said guide panels clamps and extending outwardly short of said trailer body side;

m) at least one clamp member for each of said support panels to secure said support panel to a selected trailer undercarriage I-beam adjacent said trailer body side; and

n) at least one hanger member associated with said support panel for releasably engaging and retaining the loaded weight of a container slung under said trailer undercarriage during transport.

2. Underslung container transport assembly as in claim 1 wherein each of said support panels includes a hanger member comprising at least one J-hook for engaging load-carrying pins on a container.

3. Underslung container transport assembly as in claim 2 wherein said J-hook includes an actuating rod having an accessable locking lever at an outboard end thereof, and said actuating rod is journaled to said support panel and includes a biasing spring to bias said J-hook in a locked position.

4. Underslung container transport assembly as in claim 3 wherein each said guide panel includes a lower portion extending downwardly below the lower margin of said support panel, said lower portion includes a flared flange on the outboard end thereof to assist in orienting and guiding a container into proper position therebetween for engagement with said hanger members.

5. Underslung container transport assembly as in claim 4 which includes at least one vertical backing plate secured to said cross brace and a clamp member for securing said backing plate to an I-beam of said trailer undercarriage intermediate of said guide panel I-beams.

6. Method of increasing the carrying capacity of truck trailers comprising the steps of:

a) mounting a load carrying, substantially quick-release, container engagement, support and retention assembly to the undercarriage I-beams of a truck trailer to provide a container docking space extending from an outboard side of said trailer to about a centerline of said trailer;

b) providing a plurality of universal, self-contained containers having load-carrying structural elements in at least two opposed sidewalls thereof for auto-latchingly, matingly engaging said quick-release container support assembly, the depth of said container being selected to be less than half the width of the trailer to permit retaining said containers in said docking space to one or the other side of said trailer undercarriage centerline;

c) loading said containers under the undercarriage of said trailers by engaging the load-carrying elements thereof to said container support assembly; and

d) transporting said containers in an underslung mode.

7. Method as in claim 6 wherein said containers are stackable, and sized both for said underslung transport mode and for transport stacked in the interior of said trailer body.

8. Method as in claim 7 wherein said containers are integrated, sealable and lockable for reduced tampering and theft during warehousing and transport activities.

9. Method as in claim 8 which includes the step of charging said containers with a gas selected from a product enhancing gas, a security gas and a disinfecting gas.

10. Method as in claim 8 wherein said containers include at least one of identification elements and in transit location tracking devices.
