It is designed to utilize a drawbar to pull or push heavy or exceptionally large trailored loads. When feasible, lowboy-style semi-trailers are used to minimize a load's center of gravity. Typical drivetrains are 6×4 and 6×6.Typical ballast tractor loads include oil rig modules, bridge sections, buildings, ship sections, and industrial machinery such as generators and turbines.Only a handful of manufacturers produce dedicated ballast tractors. Extra heavy duty chassis versions of mass-production tractor units are fitted with drawbar hitches and a separate ballast box as an alternative.Increasingly, remote-controlled self-propelled modular transporters (SPMT) are being employed in traditional ballast tractor/trailer roles."@en }
