Abstract
Adjustable stowable securement apparatus for use with flatbed carriers for providing both lateral and longitudinal chocking of heavy, oversized tracked or wheeled vehicles, wherein the lateral and longitudinal chocking components are operable to adjust from a stowed, flush-with-carrier-deck position to an adjustably raised position for forcibly abutting the vehicle's tires or tracks to effect positive chocking and securement of the vehicle to the flatbed carrier.
Claims22
In combination, a flatbed carrier having transverse and longitudinal sills undersupporting a flat deck, the top of said deck being characterized by at least one longitudinal track formed flush therein, and by plural transverse tracks formed flush therein at spaced locations therealong;
- plural lateral restraining apparatus each comprising a lateral load-engaging bearing plate extending into a respectively associated one of said transverse tracks and lateral positioning means for adjustably locating each said plate along a respectively associated one of said transverse tracks;
- plural reversible longitudinal restraining apparatus each comprising a restraining arm, a support member engaging said arm, and first and second anchor means for respectively releasably anchoring said restraining arm and said support member to said longitudinal track, said first and second anchor means further being operable to effect selective adjustment and positive locking of said arm and said member at selected positions therealong, said restraining arm and support member further characterized by the capability of assuming reversed positions to provide longitudinal restraint in either direction along said longitudinal track.
A heavy vehicle chocking system having both lateral and longitudinal chocking components for use on decked flatbed carriers, the system comprising in combination;
- plural lateral chocking apparatus for providing lateral restraint to a heavy vehicle stored on the carrier deck, each comprising a track formed transverse of said deck, a lateral bearing plate, and bearing plate positioning means operable to adjustably selectively position and releasably lock said plate along said transverse track, said transverse track having adjacent thereto an opening in said carrier deck, rotation means to permit said lateral bearing plate to rotate from an above deck load-engaging position to a below deck storage position;
- plural adjustably reversible longitudinal chocking apparatus for providing longitudinal restraint to a heavy vehicle, including at least one track formed longitudinally of said deck, a load restraining member, and a support element bearingly connected to said restraining member to provide support during the longitudinal loading thereof, each said member and element having separate anchorage means operable to respectively adjustably position and releasably lock said member and element along said longitudinal track, said separate anchorage means further being operable to provide relative height adjustment of said restraining member above said deck to effect relatively direct axial loading thereof;
- and said reversible longitudinal chocking apparatus being capable of being stored within said longitudinal track.
A longitudinal chocking assembly for securing a load to a flatbed carrier wherein said carrier includes transverse and longitudinal sills undersupporting a flat deck, and a longitudinal track defined in said deck, said assembly comprising
- a longitudinal chock movably mounted in said track, said longitudinal chock comprising a first anchor slidably secured to said track,
- a longitudinally adjustable restraining arm having first and second ends, said first end coupled to said first anchor block,
- a second anchor block removably secured to said track, and
- a support member having first and second ends, said first end of said support member pivotally coupled to said second end of said restraining arm, said second end of said support member pivotally coupled to said second anchor block.
A lateral chocking assembly for securing a load to a flatbed carrier wherein said carrier includes transverse and longitudinal sills undersupporting a flat deck, and a transverse channel defined on said carrier, said assembly comprising:
- a threaded shaft positioned within said channel,
- a chock plate pivotally coupled to said shaft, and
- a drive rod secured to said channel and threadably coupled to said shaft, said drive rod operable to position said plate relative to said deck.
A system for longitudinally and laterally chocking a load to a flatbed carrier wherein said carrier includes a deck, at least one longitudinal track and at least one transverse channel defined in said deck, said system comprising,
- at least one longitudinal chock slidably mounted in said track, said longitudinal chock including
- a first mounting member releasably secured to said track,
- a longitudinally adjustable compressive load member pivotally secured to said first mounting member, said compressive load member comprising first and second body members and a connecting element having a first end threadably coupled to said first body member and a second end threadably coupled to said second body member,
- a second mounting member releasably secured to said track,
- a tensile load member pivotally coupled at a first end to said compressive load member, and pivotally coupled at a second end to said second mounting member, and
- at least one lateral chock mounted in said channel, said lateral chock comprising
- a plate,
- an anchor block slidably mounted in said channel, said plate being pivotally coupled to said block,
- a shaft threadably secured at a first end to said block, and
- means for threading said shaft relative to said anchor block thereby moving said plate relative to said channel.
