Three new Cat excavators

Published 18/12, 2017 at 14:02

Three new 20t 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 company claims.

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.

Standard grade assist automates boom, stick and bucket movements, so operators stay on grade simply and effortlessly with single-lever digging. Cat Payload on-board weighing, integrated on the Cat 320 and 323 at the factory delivers load targets with on-the-go weighing and real-time payload estimates.

The new excavators do more work at a lower cost and reduce maintenance costs by up to 15% over the previous series. The new Cat hydraulic return filter boasts a 3,000h service life, a 50% increase over previous filters. A new Cat air filter with integrated pre-cleaner and primary and secondary filters extends service life to 1,000h, a 100% increase over previous designs, while a new fuel tank cap filter extends service life to 2,000h. The three fuel system filters each offer a 500h service interval. All daily maintenance checks for engine oil, fuel water separator, fuel tank water and sediment, and cooling system level are performed from ground level, making the routine faster, easier and safer.
