Reading: 16

📌 Overview

The CAT 336D2L is a medium-to-large hydraulic excavator from Caterpillar's D2 GC (Next Generation) series. The "L" stands for "Long Reach", meaning it's specifically designed for extended digging and loading applications such as deep foundation work, river dredging, slope trimming, and material handling over obstacles.

It replaced the older 336D L (D1 series) and brings significant improvements in fuel efficiency, operator comfort, technology, and emissions compliance.
