The Doosan 255 crawler excavator is a high-performance 25-ton earthmoving machine produced by the South Korean company Doosan Infracore. Essentially, it is a reinforced version of the brand’s popular mid-range models.
Its operating parameters and technical specifications have been improved thanks to increased digging force and higher lifting capacity.
The excavator is used across a wide range of applications: general construction work, excavation of foundations, loading dump trucks in quarries, and laying utilities — anywhere high productivity is required.
