Three Next Generation Cat® Excavators

October 30 2017

Three Next Generation 20-ton size class excavators from Caterpillar—the 320 GC, 320 and 323—increase operating efficiency, lower fuel and maintenance costs, and improve operator comfort compared to previous models. 

The new Cat 320 and 323 boast the industry’s highest level of standard factory-equipped technology to boost productivity. Both models are equipped with integrated Cat Connect Technology, which increases operating efficiency by up to 45 percent over traditional grading operations.

Offering guidance for depth, slope and horizontal distance to grade, the Cat Grade with 2D system helps operators reach desired grade quickly and accurately. Using the system’s E-fence feature enables the machine to work safely under structures or near traffic by preventing any part of the excavator from moving outside operator-defined set points. 

Standard Grade Assist automates boom, stick and bucket movements, so operators stay on grade simply and effortlessly with single-lever digging. 

The efficient Next Generation machines consume up to 25 percent less fuel than the previous, corresponding models. New Smart mode operation automatically matches engine and hydraulic power to digging conditions, optimizing both fuel consumption and performance. Engine speed is automatically lowered when there is no hydraulic demand to further reduce fuel usage.

More efficient than single-fan systems, the new cooling system employs multiple electric fans, which independently monitor hydraulic oil, radiator and air-to-air aftercooler temperatures to deliver the exact airflow required. 

Offering extended and more synchronized maintenance intervals, the new Cat excavators do more work at a lower cost and reduce maintenance costs by up to 15 percent over the previous series.
