Used Caterpillar 320D2LExcavator

Reading: 15

📌 Overview

The Cat 320D2L is a next-generation 20-tonne class hydraulic excavator in Caterpillar's D2 Series. The "L" stands for "Long" — indicating a longer boom and stick (arm) configuration compared to the standard 320D2. This makes it ideal for deeper digging, longer reach, and material handling applications.

It replaced the older 320DL and is part of Cat's Gen2 (Next Generation) lineup, featuring significant improvements in fuel efficiency, operator comfort, technology, and productivity.
