Abstract
A single transportation platform system capable of interfacing with standardized ISO containers, PLS truck-and-trailer systems, HSVs Fast Sealift Ships, and cargo aircraft's 463L rail and pallet locking systems. The system can be handled by a LHS equipped vehicle as a joined platform or separated into individual pallets and handled like a 463L pallet. The platform provides a pallet system that eliminates the need for a married pallet system to be used in the process of loading and supporting loads normally transported on standard CROPs when being transported on a cargo aircraft. The platform can be positioned directly on the roller assembly of a loading ramp of a cargo aircraft, such as a C-17 by a LHS equipped vehicle, so as to facilitate loading and unloading from the aircraft without the need for large cranes or K-loaders. The platform also permits combat offloads to be performed.
Description




FIELD OF THE INVENTION




The present invention relates to a platform system capable of interfacing with a wide variety of material handling equipment and transport aircraft to replace 463L logistics pallets, airdrop platforms, and Container Roll in/Out Pallets.




BACKGROUND OF THE INVENTION




The United States Department of Defense and, in particular, the United States Army have recently identified a need in the handling and transporting of logistics from location to location. Specifically, the United States Army has indicated that it is in need of a system that would be capable of supporting logistics and/or other materials that can be easily and convenient transported via air, sea, rail, and road without requiring extensive support equipment or modification of the transport vehicle. In other words, the United States Army is in need of a single cargo system that is capable of interfacing with existing material handling equipment and various transport aircraft cargo systems, which is capable of replacing existing 463L material handling system, airdrop platforms, and Container Roll In/Out Platforms (CROPs) such that logistics that have been packaged for one mode of transportation (i.e. air, sea, rail, or road) can be easily loaded for another mode of transportation without the need to repackage.




By way of background, the existing 463L material handling system generally employs pallets that are approximately 96″×108″ in size and include a series of tongues extending horizontally about the periphery of the pallet. These tongues are sized to be received and retained within rails formed in aircraft cargo systems.




Often times, one type of cargo system must be packaged on another cargo system for it to be used in more than one mode of transportation. For example, in order for CROPs to be loaded onto military transport aircraft, such as the C-17 and the C-130, they must first be loaded on a series of 463L pallets. The CROPs include a complexly shaped underside having numerous support members therealong, which prevent rolling of the CROPs along the aircraft cargo roller system. Therefore, in order for CROPs, or for that matter any flatrack or ISO container, to be transported via aircraft, each CROP must be loaded onto three standard 463L pallets. To this end, these three 463L pallets are first coupled to each other in a “married” configuration. Next, a large crane is required to lift the CROP onto the “married” 463L pallets. The load must then be secured to the 463L pallets with restraint straps or chains. Finally, Material Handling Equipment, such as a K-loader, is used to transport the entire assembly, including the “married” 463L pallets and CROP, and load it onto the loading ramp of the aircraft where it is then moved into the cargo area. This procedure is necessary because the CROP cannot be rolled directly on the roller assemblies of the aircraft because of their complexly shaped lower surface.




In order for CROPs, flatracks, or ISO containers to be loaded onto the “married” 463L pallets, heavy equipment must be available at the loading site to lift such heavy cargo onto the 463L pallets. Traditionally, a crane and a K-loader are airlifted to the areas where the aircraft is to be loaded and unloaded, which increases the complexity of the operation.




The use of “married” 463L pallets further limits how the cargo is to be unloaded. That is, the “married” 463L pallets are unable to withstand the forces generated during a “combat offload,” where the cargo is permitted to simply roll off the loading ramp of the aircraft while the aircraft is moving along a runway, taxiway, or parking ramp immediately after landing. Since combat offloads are prohibited when employing a married pallet system, the delivery of CROPs is limited to only those locations where a large crane and K-loader are available. This eliminates the possibility of off-loading cargo at generally small, austere airfields where such equipment is not available. Therefore, material handling equipment such as the crane and the K-loader must be flown ahead of time on a separate aircraft to the location where the aircraft carrying the CROPs is to be offloaded. On occasion, as many as three flights may be needed to deliver one CROP to an austere airfield (i.e., one flight to transport a K-loader, one flight to transport a crane, and one flight to transport the CROP). As can be readily appreciated, this adversely effects the deployment of materials and equipment.




Additionally, conventional pallet systems limit the carrying capacity of the C-17 in that they permit only three CROPs to be carried down the center of the aircraft on the 463L interface pallets, which are secured in the 108″ air drop rail system (ADS).




Accordingly, there exists a need in the relevant art to provide a platform system that eliminates the need for a married pallet system to be used in the process of loading and supporting a CROP being transported on a cargo aircraft. Furthermore, there exists a need in the relevant art to provide a single platform system that can be positioned on the roller assembly of a loading ramp of a cargo aircraft, such as a C-17, that also is compatible with PLS systems, and aircraft pallets systems such that the entire assembly can be loaded onto or unloaded from the aircraft without the need for a large crane (i.e. combat offloads). Currently, 463L logistics pallets, airdrop platform, and CROPs are three distinct and different logistics systems. There exists a need to combine these logistics systems into a single system. There exists a need in the relevant art to provide a platform system that overcomes the disadvantages of the prior art.




SUMMARY OF THE INVENTION




According to the principles of the present invention, a single modular transportation platform is provided having an advantageous construction. The platform is capable of interfacing with standardized ISO containers, PLS truck-and-trailer systems, and cargo aircraft's 463L rail and pallet locking systems. The platform provides a system that eliminates the need for a married pallet system to be used in the process of loading and supporting CROP type cargo loads being transported on a cargo aircraft. The platform can be positioned on the roller assembly of a loading ramp of a cargo aircraft, such as a C-17, so as to facilitate loading and unloading from the aircraft by a PLS Vehicle without the need for large cranes. The platform also permits combat offloads to be performed.




Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

90


extending through EADS platform


10


to permit EADS platform


10


and any cargo loaded thereon to be conveniently lifted with a conventional fork lift without the need to tear down the loaded cargo.




Turning now to

FIGS. 1-3

, and


7


, EADS platform


10


employs the plurality of interface clamp systems


100


to engage and retain multiple EADS platforms


10


together along a mated edge or couple attachments to the remaining unmated edges thereof. According to the preferred embodiment, four interface clamp systems


100


are available for use along each of the pair of ends


44


of EADS platform


10


. As best seen in

FIG. 7

, each of the plurality of interface clamp systems


100


includes an interface clamp


102


coupled to end


44


of EADS platform


10


and an opposing interface clamp receptacle


104


formed on an adjacent EADS platform


10


′ for coupling with interface clamp


102


. More particularly, interface clamp


102


includes a symmetrical housing body


103


which fits into opposing interface clamp receptacles


104


and is centered on the interface plane, two clamping jaws


105


which protrude from opposing sides of housing body

, and two drive screws which are positioned symmetrically across the interface plane. Clamping jaws


105


rotate to engage an internal rib in interface clamp receptacle


104


, and draw a pair of EADS platforms


10


together in a secure slack-free connection. Two configurations of interface clamp


102


are used. The first configuration contains clamping jaws, which rotate upward to engage. The second configuration contains clamping jaws, which rotate downward to engage. A pair of each configuration is used at the interface plane to carry both upward and downward bending moments across the interface of two mated EADS platforms


10


. The drive screws may be operated directly with a hand tool, or operated remotely by crank, wheel, or ratchet attached to a linkage for improved access to operate the interface clamps


102


with loaded EADS platforms


10


. The interface clamp


102


is commercially available as a slack-free connector for ISO containers. The interchangeable interface clamps


102


may be permanently fixed to one EADS platform


10


in a symmetric pattern that preserves the interchangeability of all EADS platforms


10


. An alternative design would make use of commercially available slack-free ISO connectors that bolt to an EADS platform


10


on one side, and engage a clamping jaw into the interface clamp receptacle


104


on the opposing EADS platform


10


on the other side. This design may be used to attach A-arm assembly


120


or wheel assembly


130


.




As seen in

FIGS. 9 and 10

, employing the plurality of interface clamp systems


100


, a first EADS platform


10


may be mated with a second EADS platform


10


′ to define a single, substantially co-planar pallet. The plurality of interface clamp systems


100


aid in drawing EADS platform


10


and


10


′ together to form a rigid platform transportable by LHS equipped vehicles.




However, as it should be understood, interface clamp systems


100


enable EADS platform


10


and


10


′ to be easily coupled, but equally importantly, to be easily separated to facilitate the handling of EADS platform


10


in smaller, lighter segments.




Referring now to

FIGS. 9-11

and


15


-


19


, EADS platform


10


includes a removable A-arm assembly


120


. As best seen in

FIG. 11

, A-arm assembly


120


generally includes a main support member


122


, a pair of support arms


124


fixedly coupled and upwardly-extending from main support member


122


, a lateral cross member or bail bar


126


generally extending horizontally between the pair of support arms


124


, and an optional reinforcement member


128


similarly extending between the pair of support arms


124


. This arrangement generally defines an A-shaped configuration. However, it should be appreciated that the present invention should not be regarded as being limited to the present configuration as any arrangement that facilitates interface with the load handling system (LHS) of a transporting vehicle or Palletized Load System (PLS) equipped truck is to be regarded as within the scope of the present invention.




However, according to the presently preferred embodiment, main support member


122


is preferably a generally square-shaped tubular member having a pair of interface clamps


102


and a pair of interface clamp receptacles


104


for mating with corresponding interface clamp receptacles


104


and interface clamps


102


, according to the aforementioned interface clamp system


100


. Such arrangement fixedly, yet releasably, couples A-arm assembly


120


to EADS platform


10


. As can be seen in

FIGS. 9-11

, main support member


122


may be a single unitary member that spans generally across end


44


of EADS platform


10


, or may be two separate members located only adjacent interface clamp systems


100


. Each of the pair of support arms


124


preferably includes an I-beam shaped cross-section to resist bending forces, while lateral cross member


126


is preferably circular in cross-section to permit interface with the LHS of the transport vehicle. A unique feature of bail bar


126


allows it to articulate in such a manner as to alleviate unwanted downward forces being placed on A-arm assembly


120


by the load handling vehicle which could transmit undesirable loads to the cargo loader or aircraft roller systems. Bail bar


126


may optionally be pivotally coupled to support arms


124


via a hinge connection between bail bar


126


and support arms


124


and a locking stud (not shown) extending through bail bar


126


and support arms


124


to prevent unwanted relative rotation. This pivotal arrangement permits bail bar


126


to be folded downward to minimize the overall height of EADS platform


10


, thereby permitting EADS platform


10


to be used in smaller cargo aircraft. Additionally, A-arm assembly


120


may be optionally pivotally coupled to EADS platform


10


to permit A-arm assembly


120


to be folded downward onto an upper empty surface of EADS platform


10


to simplify storage of EADS platform


10


. To this end, support arms


124


may be hingedly coupled to main support members


122


and lockable in a lowered and/or raised position via locking studs.




As seen in

FIG. 15

, during operation, the cargo handling system of the transport vehicle grasps lateral cross member


126


to lift and roll EADS platform


10


(and


10


′) onto the bed of the vehicle. Once into position near lower cargo door


26


or other transport vehicle, cargo-handling system of the transport vehicle releases EADS platform


10


(and


10


′) onto lower cargo door


26


, according to known loading principles.




Referring now to

FIGS. 12-14

, EADS platform


10


further includes removable, adjustable wheel assembly


130


, which is releasably coupled to EADS platform


10


at an unmated end


44


, which permits EADS platform


10


to roll into or out of a standard ISO container and across the deck of aircraft cargo ramp, K-loader floor, and/or PLS trailer. To this end, adjustable wheel assembly


130


includes a generally angular bracket member


132


. Bracket member


132


includes a plurality of interface clamp systems


100


mounted thereto to selectively couple adjustable wheel assembly


130


to an unmated end


44


of EADS platform


10


, according to the aforementioned principles. Adjustable wheel assembly


130


further includes preferably a pair of wheel roller assemblies


134


slidably coupled to bracket member


132


. Specifically, bracket member


132


includes a pair of retaining flanges


136


that extend along edges


138


thereof. At least one of the pair of retaining flanges


136


includes a hook portion


140


that engages each of the pair of wheel roller assemblies


134


to maintain proper coupling of the pair of wheel roller assemblies


134


with bracket member


132


. However, it should be appreciated that the pair of retaining flanges


136


and hook portion


140


permit each of the pair of wheel roller assemblies


134


to slide laterally relative to EADS platform


10


. In other words, the pair of wheel roller assemblies


134


may be positioned in a generally wide-stance (see

FIG. 12

) for use in rolling across a PLS trailer or the pair of wheel roller assemblies


134


may be positioned in a generally narrow-stance (see

FIGS. 13 and 14

) for rolling on a floor or for storage.




Still referring to

FIGS. 12-14

, each of the pair of wheel roller assemblies


134


is adjustable to provide more or less roller contact with a floor. Specifically, each of the pair of wheel roller assemblies


134


includes a first support member


142


and a second support member


144


. First support member


142


is generally U-shaped and slidably engages hook portion


140


and retaining flanges


136


. Second support member


144


is generally U-shaped and is pivotally coupled to first support member


142


via a pivot pin


146


. First support member


142


and second support member


144


each includes a plurality of adjustment holes


148


. Second support member


144


rotatably supports a roller


152


. An indexing or clevis pin


150


extends through corresponding adjustment holes


148


formed in first support member


142


and second support member


144


to adjust the extension and/or retraction position of roller


152


relative to lower surface


40


of EADS platform


10


. In this regard, rollers


152


may be quickly and conveniently extended into one of a number of operating positions (

FIGS. 12 and 13

) or retracted into a stowed position (FIG.


14


). Accordingly, EADS platform


10


to be directly loaded and unloaded by a LHS equipped vehicle directly to or from a C-17, K-loader, or ISO container without the use of material handling equipment or exceeding load bearing footprint capacity, since the load is evenly distributed across the face of several rollers


152


. It should be understood that any number of rollers may be used to further distribute these loads.




The modular configuration of EADS platform


10


provides the ability to attach the necessary equipment, such as A-arm assembly


120


, adjustable wheel assembly


130


, or additional EADS platforms


10


′, for rapid reconfiguration of loads without unloading each EADS platform


10


. Each EADS platform


10


is identical and, thus, can be easily mated with adjoining EADS platform


10


without the need for special mating platforms. Therefore, by joining and locking adjacent EADS platforms


10


and attaching A-arm assembly


120


and adjustable wheel assembly


130


, the joined EADS platform


10


can be handled and transported like a full size CROP. However, the joined EADS platform


10


may also be separated into pallets and transport via forklift, aircraft, etc. without the need to tear down the loads.




EADS platform


10


is may be airdropped as an individual pallet using all 108″ airdrop rail systems or as a joined EADS platform


10


using the 88″ logistics rail system of the C-17. When dropped individually, features such as the plurality of heavy lift rings


82


and/or the plurality of retractable restraints


84


permit EADS platforms


10


to be drawn together on the ground to form the joined EADS platform


10


, which may be easily removed by a LHS equipped vehicle. Without the use of Material Handling Equipment (MHE), any drop zone vehicle may use organic retractable restraint cables


84


attached to the plurality of heavy lift rings


82


to maneuver each EADS platform


10


in close proximity to another EADS platform


10


to permit latching of the platforms together.




According to the principles of the present invention, EADS platform


10


provides a single transportation platform capable of interfacing with standardized ISO containers, PLS truck-and-trailer systems, and cargo aircraft and HSV rail and pallet locking system. That is, EADS platform


10


provides a pallet interface system that eliminates the need for a married pallet system to be used in the process of loading and supporting CROP type loads being transported on a cargo aircraft. Furthermore, EADS platform


10


provides a system that can be positioned on the roller assembly of a loading ramp of a cargo aircraft, such as a C-17, that can be loaded onto or unloaded from the aircraft without the need for a large crane, and which permits combat offloads to be performed. Still further, EADS platform


10


provides a system that overcomes the disadvantages of the prior art.




It will be appreciated that a principal advantage of the present invention is that no crane is required to first place EADS platform


10


on a married pallet system and a K-loader used to place the entire assembly on the loading ramp of the aircraft. This also allows cargo to be off loaded at airfields where a large crane is not available for removing the cargo-supporting platform from its pallet system.




The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
