Beam & Dolly transporters are engineered to spread the transported load to meet highway and bridge load limits. Beam and Dolly Transporters are ideally suited for moving heavy loads, including power plant equipment (transformers, turbines and generators), refinery equipment (including pressure vessels and exchangers), and other heavy items. Bigge operates a fleet of Beam and Dolly Transporters that will be custom engineered and assembled for each project.
