More Comfort – More Performance – More Versatility

  • Nearly 35% More Reach

    Cat Long Reach Excavation Excavators reach nearly 35% farther than those with the standard reach configuration, with approximately 66% of the digging force.

  • Designed to Dig

    Reinforcements in the front linkage and frame allow digging power at a distance without sacrificing durability. A heavier counterweight than equivalent standard reach excavators provides greater stability. Get added versatility with optional tool control for select hydro-mechanical tools

  • Stable Foundation

    The heavy-duty, high, wide undercarriage provides a stable, rugged platform for long-reach digging and loading applications with high ground clearance.

  • Next Gen Features

    Take advantage of Cat Next Generation Excavator features including improved operator comfort, reduced maintenance costs, and better fuel economy. Long reach excavation excavators are compatible with Next Generation Excavator technologies.
