The new Cat 323F L is a purpose-built machine powered by a fuel-efficient U.S. EPA Tier 4 Final C7.1 ACERT engine. With plenty of counterweight, robust structures, a state-of-the-art hydraulic system, and Cat Grade Control Depth and Slope* you can move tons of material – literally – all day long with tremendous stability, speed, and precision. When you add in a quiet operator environment that keeps you comfortable and productive, easy-to-reach service points that make your routine maintenance fast and simple, and multiple Cat work tools that help you take on a variety of tasks, you just won’t find a better, more efficient 23-ton excavator – any place, anywhere. Bottom line: If you are in the business of road construction, underground utilities, or commercial and residential site development, you need the versatile Cat 323F L in your fleet. *Cat Grade Control Depth and Slope hardware is standard with R2.9 (9'6") sticks. See "Integrated Technologies" within the "BENEFITS AND FEATURES" tab for more details.
