CAT Puts Century-Old Train Tech to Work in New Electric Drive Dozer

Caterpillar is leveraging the proven efficiency of diesel-electric locomotives in a new, heavier electric drive dozer. This century-old concept involves diesel engines spinning up generators to power high-torque electric motors. The result is promised efficiency gains in the new dozer, which builds on established technology. The combination of diesel engines and electric motors has been a staple of American railroads for generations, delivering consistent and high-efficiency performance. By applying this concept to a dozer, Caterpillar aims to replicate the success of diesel-electric locomotives in a heavier, more demanding application. The efficiency gains in the new dozer are touted as incredible, but specific details on the extent of these gains are not provided.
