Abstract
A convertible trailer system includes a convertible trailer having a segmented lower deck, and a segmented upper deck mounted thereover. The segmented lower deck includes floating forward and rear belly ramps which are independently actuable relative to each other so as to be selectively raised and lowered relative to a pair of side rails which define the belly forward of the trailer wheels. When in a fully lowered position the belly ramps are lowered to a lower extremity between the pair of side rails so as to be substantially entirely below uppermost edges of the pair of side rails. When in an elevated position the belly ramps are elevated so as to be co-planar with or above the uppermost edges of the side rails whereby freight may be loaded laterally onto the belly ramps over the pair of side rails.
Claims11
A convertible trailer system comprising:
- a convertible trailer having a segmented lower deck, a segmented upper deck mounted onto said lower deck by selectively actuable telescopic stanchions, said stanchions actuable by actuators so as to raise and lower said upper deck over said lower deck between a lowered position, an intermediately elevated position, and a fully elevated position, wherein in said fully elevated position said upper deck is elevated above said lower deck so as to allow loading of vehicles or freight onto said lower deck, wherein in said intermediately elevated position said upper deck is below said fully elevated position so as to be snugly adjacent uppermost extremities of said vehicles or freight on said lower deck, wherein in said lowered position said upper deck rests on a mid-section of said lower deck and on elevated wheel-wells of said lower deck,
- wherein said trailer includes a spaced apart longitudinally extending parallel pair of side rails and wherein said segmented lower deck includes a floating forward segment forward of said mid-section and independently actuable so as to be selectively raised and lowered relative to said pair of side rails, and wherein when in said fully lowered position said forward segment is lowered to a lower extremity between said pair of side rails substantially entirely below uppermost edges of said pair of side rails, and
- wherein when in said elevated position said forward segment is elevated so as to be co-planar with or above said uppermost edges of said side rails whereby freight is loadable laterally sideways onto said forward segment over said pair of side rails,
- wherein said forward segment is a floating forward segment and wherein said segmented lower deck further includes a floating rear segment interposed between said floating forward segment and said mid-section of said lower deck, said floating rear segment independently actuable so as to be selectively raised and lowered and inclined relative to said pair of side rails and independently of said floating forward segment, and wherein, when in said fully lowered position, said floating rear segment is lowered to a lower extremity between said pair of side rails entirely below uppermost edges of said pair of side rails and substantially aligned with lower edges of said pair of side rails,
- and wherein, when in said elevated position, said floating rear segment selectively positionable so as to be inclined or so as to be to horizontal and substantially co-planar with or above said uppermost edges of said side rails, whereby freight is loadable from a direction laterally oriented relative to the length of said trailer so as to load sideways onto said floating rear segment over said pair of side rails,
- and wherein said segmented lower deck further includes a lower pair of wheel-engaging members, and wherein said pair of wheel-engaging members are parallel and laterally spaced apart and wherein said pair of wheel-engaging members are adjacent to said side rails of said pair of side rails so as to form a longitudinally extending central opening between said pair of wheel-engaging members,
- and wherein said central opening is adapted to support removable decking mounted therealong,
- and wherein said segmented lower deck further includes removable decking mountable in a central opening in said segmented lower deck to form a substantially solid continuous floor over said central opening,
- and wherein said decking has an upper surface which, when said decking is mounted in said central opening is raised slightly above an upper surface of said wheel-engaging members.
