The Frame That Turns a Marine Box Into a Road Load
A shipping container is not a trailer until something underneath it makes it one. This 20ft intermodal chassis is that something: a purpose-built frame whose twist locks engage the container’s corner castings so the box itself becomes the structural deck. Nothing overhangs, nothing needs strapping down, and the loaded profile stays low.
Drayage operators, container dealers, freight haulers and owner-operators building out a transport fleet are the natural buyers. So are businesses that repeatedly shuttle a loaded box between a port, a yard and a jobsite and have grown tired of paying someone else to do it. With 67,200 lbs of carrying capacity against a tare weight of just 6,700 lbs, the chassis takes up very little of your legal gross before the cargo does.
Dimensions That Match the Box
Overall length runs 23 ft 6 in and width a full 8 ft, which mirrors a 20ft container’s footprint almost exactly. The 48 in frame height puts the container floor at standard dock level, so a forklift or pallet jack moves straight from the warehouse into the box without a ramp or a dock plate adjustment. Eight tires across two axles spread the weight of a fully loaded container evenly, which is what gives this kind of chassis its predictable braking and its settled behavior at highway speed.

Before you buy any chassis, confirm three things. First, that your boxes are genuinely 20ft ISO units, because a non-standard or modified container may not present its castings where the twist locks expect them. Second, that your tractor is rated for the combined loaded weight, not just the chassis. Third, look over the tires, the brake function and the condition of the locking pins, since the pins are the single component doing the work of every strap and chain you are not using. Sizing itself is simple here because the chassis is matched to one box length rather than adjustable, which removes the guesswork that comes with a sliding or extendable frame. It is also worth planning where the chassis will sit when it is not under a box, since eight tires and twenty-three feet of steel need somewhere sensible to live between runs.
Freight on a chassis is not the same as freight on a boxed product, so the sensible first step is a delivered quote. Send us the destination via our contact page and we will confirm the total, the lead time and the paperwork. Delivery is a flat rate by region from our Sacramento yard – local, nationwide and international – and the exact rate shows at checkout. Other chassis and heavy trailers are listed in Container Chassis & Trailers.
