This invention relates to the extendable frame of the container trailers/chassis and more particularly to the subframe sliding fifth wheel addition with the pneumatic suspension system.
The lead (slide out fifth wheel) container chassis has typically been seen on only a 20′ container chassis/trailer which does not take into consideration now the updated Long Combination Vehicles rules in place for commercial highway travels.
The extendable container trailer/chassis frame has only been transporting one container at a time, thus causing more traffic and delays in rail yards and roads. Prior solutions to the problem have been directed to additional beam placements, however the container placed at the front doors would have no access and would then need to be rearranged with the container placed at the rear.
The invention is directed to improve the supply chain by strengthening an extendable container trailer/chassis frame and add a pneumatic system to the subframe which would allow a fifth wheel to slide out (and close) to allow coupling to another trailer/chassis.
The pneumatic system would allow for extending the frame to either accommodate a 20′, 40′ or a 45′ container. The system would also allow to slide out the fifth wheel and provide air supply the to coupling/connecting of the rear trailer/chassis.
As the pneumatic system would be flowing through the chassis, an air suspension system has been selected as the safest and smoothest method for this equipment.
All three size of the extendable frame were shown together on the GA drawing which consists of:
OPTION 1, 20 Foot Container; shows the top & side view with the fifth wheel in the closed position the container would be placed on top of. There is also an open position of the side which shows the fifth wheel on the subframe slid out towards the rear. which could couple to another trailer/chassis.
OPTION 2, 40 Foot Container; shows the sideview of the trailer/chassis frame stretched to 40′ with the fifth wheel in closed and open position (with the subframe slid out towards the rear, which could couple to another trailer/chassis).
OPTION 3, 45 Foot Container; shows the sideview of the trailer/chassis frame stretched to 45′ with the fifth wheel in closed and open position (with the subframe slid out towards the rear, which could couple to another trailer/chassis).
