> Do you know if trucks running at 44 (such as in the UK) use special trailers like those Cozad trailers? They'd probably not look like that, but they would be different from the standard 53 foot, 8-tire, 2-axle trailer. Maybe the same box dimensions and height, but with 3 axles. Possibly double chained 20ft trailers with 2 axles each. Once you go over container shipping weight thresholds (which might be 44T like you say), you stop seeing box trucks. The cosad trailers are amazing for their weight capacity, but typically used for heavy machinery and are designed with low floors which heavily constrains how they distribute the weight (and thus the tiered chains of 9-tire per axle bogies). There are other designs out there, but that trailer was just what I searched for because they're from my hometown and I used to be a truck driver.
