A lowboy (doble gota) is the double-drop trailer whose main deck rides just above the pavement, built for the tallest and heaviest equipment: excavators, transformers, industrial machinery. Most lowboy freight runs permitted as oversize or overweight.
A lowboy, known in Mexican Spanish as cama baja or simply lowboy, is the double-drop trailer: the deck drops once behind the gooseneck and again ahead of the rear axles, leaving a main deck that rides close to the pavement. That well is the point, since it accepts the tallest cargo the highway network can move: excavators and dozers, transformers, presses, generators, and plant machinery. Configurations scale with the mission, more axles for more weight, and the detachable-gooseneck variant (RGN) lets tracked equipment drive on under its own power.
Lowboy freight is heavy-haul, and it lives inside the oversize/overweight permit world on both sides of the border: route surveys, state and federal permits, escort requirements, and curfews. Treat every lowboy move as an engineered project. Exact dimensions and weight, with the machine's attachments counted, decide everything downstream, and the crossing must be chosen for physical capability, with Colombia Bridge a frequent answer in the Laredo corridor. The genuinely binational lowboy carrier pool is small, known, and busy, so lead time is a feature of the product. One vocabulary note for Spanish-language postings: the correct Mexican term is 'cama baja' (or simply lowboy); postings using literal mistranslations confuse carriers and read as inexperience.
