From groundwork and drainage to demolition and quarry work, the crawler excavator is one of the most relied-on machines in construction. But with so many models and configurations to choose from, how do you pick the right one for your business?

At Kellands Plant Sales, we supply the full range of Develon crawler excavators, from nimble mid-sized machines to heavy-duty site giants. In this guide, we’ll help you compare specs, assess workloads and choose with confidence.

What Is a Crawler Excavator?

A crawler excavator (also known as a tracked excavator) uses a tracked undercarriage to provide superior traction and stability on soft, uneven or rough terrain. Compared to wheeled excavators, they’re slower to move but far better suited to muddy, sloped, or unstable ground.

Key Considerations When Choosing a Crawler Excavator

1.

Site Conditions

If you’re working on soft ground, steep inclines or in poor weather, a crawler excavator provides better grip and lower ground pressure than a wheeled option.

2.

Machine Size and Weight Class

Develon crawler excavators are available in a wide range of sizes. Some popular examples include:

  • DX140LC-7 – 14-tonne class, ideal for general civils, groundwork and site prep.

  • DX225LC-7 – 23-tonne class, with serious digging power and fuel efficiency.

  • DX300LC-7 –-30-tonne range, excellent for deep trenching and heavy loads.

  • DX420LC-7 – Heavy-duty machine for demolition, quarry or mass excavation work.

3.

Attachments and Hydraulics

Need to run a breaker, grapple, or tiltrotator? We’ll help match your machine’s auxiliary hydraulics and quick coupler setup to your chosen attachments.

4.

Transport and Access

Make sure your haulage or trailer setup can legally transport the weight of your chosen machine — including any add-ons like buckets or counterweights.

5.

Fuel Efficiency and Comfort

Develon machines are known for low fuel consumption and excellent cab comfort. Look for features like auto idle, load-sensing hydraulics, and ergonomic controls to keep your team productive all day.
