How to Read the Chart
You should focus on several key specifications when using the Excavator Size Chart:
1.Operating Weight: This value tells you how much the machine weighs. Heavier excavators provide more stability and lifting capacity, but require stronger ground support and specialized transport.
2.Digging Depth: This measurement shows how deep the excavator can dig. You need to match this to your trenching, foundation, or utility installation requirements.
3.Dump Height: This figure indicates the maximum height the excavator can dump material. It matters when loading trucks or stockpiling material.
4.Reach: This specification describes how far the boom can extend. Greater reach allows you to cover more ground without repositioning the machine.
5.Bucket Capacity: This value determines how much material you can move per cycle. Larger buckets increase productivity for bulk excavation.
6.Horsepower (Net Power): This number reflects the engine’s output. Higher horsepower means faster cycle times and better performance in tough conditions.
Note: Always consider the ground conditions and jobsite access when comparing models. Larger machines may not fit in restricted spaces, while smaller models may lack the power for heavy-duty tasks.
Industry experts recommend you prioritize the following when comparing models:
| Specification | Why It Matters |
| Size | Match machine size to jobsite constraints and project scale. |
| Weight | Ensure the ground can support the excavator and avoid instability. |
| Power | Select higher horsepower for demanding applications like trenching in hard soil. |
| Digging Depth | Confirm the machine can reach the required depth for your project. |
| Available Attachments | Choose models that support the attachments you need for versatility. |
When you use the Excavator Size Chart, you gain a quick reference for all major CAT models. You can compare specs side by side and make informed decisions based on your project’s unique requirements.

FAQ
What is the most important spec when choosing a CAT excavator?
You should focus on operating weight first. This spec determines lifting capacity, transport needs, and jobsite compatibility. Always match the machine’s weight to your project’s demands.
How do I know if I need a mini or small CAT excavator?
Mini excavators work best for tight spaces and light tasks. Small excavators offer more power and reach for general construction. Review your jobsite size and workload before deciding.
Can I use the same attachments on different CAT excavator models?
You can use many attachments across models, but always check compatibility. Each excavator supports specific couplers and hydraulic flows. Consult your CAT dealer for guidance.
How often should I service my CAT excavator?
You should follow the maintenance schedule in your operator’s manual. Most CAT excavators require daily checks and scheduled service every 250 hours. Regular maintenance extends machine life.
What is the difference between tracked and wheeled CAT excavators?
Tracked excavators provide better stability on rough terrain. Wheeled excavators move faster on paved roads and suit urban projects. Choose based on your jobsite conditions.
Do I need special permits to transport a large CAT excavator?
