Doosan Crawler Excavators: A Tradition of Excellence

You’ll find a crawler excavator model equipped for nearly any digging, lifting and loading application—including confined roadways, major construction projects, mass excavation, heavy-duty mining, scrap handling and more.

Most models feature a long carriage (LC) design that optimizes performance in heavy digging and lifting operations. Additional options include additional counterweight and boom and arm options, including a super long reach option on some models, so you can handle whatever the jobsite throws at you.
