Intermodal chassis

An intermodal chassis adapted for carrying a 53 foot shipping container that is loaded with cargo along its entire 53 foot length, for over-the-highway transport, the chassis comprising:

• a front bolster and a rear bolster, with a frame structure extending longitudinally therebetween and sized to carry said 53 foot shipping container;
• a gooseneck portion of said frame structure extending longitudinally rearward from said front bolster and having a top surface sized to fit within a tunnel depression of said shipping container;
• a kingpin mounted on a bottom surface of said gooseneck portion at a position between 36 inches and 48 inches rearward of a rear face of said front bolster;
• a main portion of said frame structure extending longitudinally rearward from said gooseneck portion and interconnecting with said rear bolster;
• a rear axle positioned longitudinally under said main portion of said frame structure such that a kingpin-to-rear-axle length is no more than 40 feet;
• and
• a forward axle positioned longitudinally under said main portion of said frame structure between said gooseneck portion and said rear axle such that a forward-to-rear-axle length is at least 12 feet, the combination of said kingpin position, said kingpin-to-rear-axle length, and said forward-to-rear-axle length allowing said chassis to carry said 53 foot shipping container with said container loaded with cargo along its entire 53 foot length and free from reducing cargo weight positioned rearward of said rear-axle.
