The machine is available with multiple front linkage configurations and auxiliary hydraulic options to suit various applications, from foundation digging and road construction to trenching and energy facility projects.
CAT 320D2L delivers strong digging performance with a maximum digging depth of 6.8 m, maximum digging radius of 10.27 m, and maximum unloading height of 7.35 m. The bucket capacity is 1.0 m³, and the machine achieves a maximum travel speed of 5.4 km/h. The spacious cab features an ergonomic design, air conditioning, and a color graphic monitor for improved operator comfort, visibility, and control.
CAT 320D2L is designed for durability and easy maintenance. The robust structure and convenient service access points, combined with extended maintenance intervals and advanced filtration, minimize downtime and keep the machine working efficiently. With proven reliability, excellent fuel economy, and versatile performance, the 320D2L is a solid choice for contractors who need a dependable mid-size excavator for a wide range of job sites.
