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. 

Cat engines provide power ratings from 121 to 162 hp for the three new excavators. The Next Generation machines consume 20% to 25% less fuel than the previous, corresponding models.

Still the 20-ton class standard, the new Cat 320 raises the bar for efficiency with integrated Cat Connect Technology that advances productivity gains. Standard technology combined with lower fuel and maintenance costs deliver low-cost production in medium- to heavy-duty applications.

Designed for low- to medium-duty applications, the Cat 320 GC combines productivity features with reduced fuel consumption and maintenance costs. The result is high reliability and low cost-per-hour performance.

Delivering high production performance, theCat 323boasts standard integrated Cat Connect Technology and the most power and lift capacity in the line. These features combine with lower fuel consumption and reduced maintenance costs to deliver maximum productivity at the lowest cost.

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% 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. The standard 2D system can be upgraded to Cat Grade with Advanced 2D or Cat Grade with 3D.

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.
