33’ Bridgemaster Extendable 3-Axle Chassis

Carries one 20' ISO container


The 33' Bridgemaster chassis can carry one 20 ft. ISO container rated for 24 metric tons (using a 16,200 lb tractor). Its sliding frame allows this chassis to extend to a maximum 41' length, allowing it to carry heavy-loaded 20' ISO containers that would be illegal to transport over the road on a standard 23.5' Slider chassis.

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