Our 31' HD Bridgemaster model provides an even higher carrying capacity for one 20' ISO container than either the 23.5' Slider or 33' Bridgemaster. The rolling beam system allows this trailer to extend to a maximum 41' length, allowing it to safely and legally transport one heavy-loaded 20' ISO container.

This extendable and heavy-duty container chassis is assembled in the USA and built to last, featuring state-of-the-art fabrication, welding, and paint systems.
