Reading: 30

📌 Overview

The Cat 323D2L is a medium-class, long-reach (L) hydraulic excavator from Caterpillar's D2 Series. The "L" stands for Long Reach, meaning it features an extended boom and arm configuration designed for applications requiring greater reach — such as dredging, riverbank work, demolition, landscaping, and deep excavation.

It sits in the ~23-tonne operating weight class and is powered by the reliable Cat C4.4 ACERT® engine, meeting Tier 4 Final / EU Stage V emission standards.
