Chapter 1: The Foundation – Understanding Excavator Size Classes
Before diving into specific models, it’s crucial to understand how excavators are categorized. Size is primarily determined by operating weight, which directly correlates to power, reach, dig depth, and, most importantly, application.
- Micro/Mini Excavators: Typically under 6 tons (13,000 lbs). Ideal for tight-access work and light-duty tasks.
- Small Excavators: Ranging from 6 to 10 tons (13,000 to 22,000 lbs). A versatile step up from mini excavators for small to medium projects.
- Medium Excavators: Ranging from 10 to 30 tons (22,000 to 66,000 lbs). The workhorses of construction, demolition, and utility projects.
- Large/Big Excavators: Ranging from 30 to 85+ tons (66,000 to 180,000+ lbs). Reserved for major earthmoving, mining, and large-scale infrastructure projects.
Specialized categories like Wheel Excavators (defined by their undercarriage) and New Energy Excavators (defined by their power source) can fall into these size classes.
