In 2022, it was reported that the total expenditure for construction projects worldwide grew to over USD$ 11 trillion (approximately AUD$ 16.6 trillion), which is 13% of the global GDP. This only shows that the construction industry isn’t showing any signs of decline, given the fact that there are major and minor projects being carried out here and there. (1)
A significant part of these construction projects is the site preparation, demolition, or earthmoving operation that greatly involves excavators. That’s the reason why the market for these machines keeps growing, amounting to USD$ 75.85 billion (AUD$ 113 billion) in 2023. (2)
But with all the excavator sizes, you might find it challenging to choose the best one for your construction project’s needs. So, here’s a guide for you:
Understanding Excavator Size Categories
When it comes to excavators, size really does matter. But bigger isn’t always better – it all depends on the job at hand.
Let’s explore the different size categories and what they’re best suited for:
Mini or Compact Excavators (0.5 to 6 tons)
Think of these as the nimble acrobats of the excavator world. They’re perfect for small jobs and tight spaces where larger machines would struggle to maneuver. If you’re working on landscaping projects or in urban areas with limited space, these compact powerhouses are your go-to choice.
Key benefits:
- Easy to transport from site to site
- Ideal for working in confined spaces
- Cause less damage to existing landscapes
Mid-Size Excavators (6 to 25 tons)
These are the jack-of-all-trades in the excavator family. They offer a great balance of power and maneuverability, making them suitable for a wide range of construction projects. If you’re a general contractor handling various types of jobs, a mid-size excavator might be your best bet.
Key benefits:
- Versatile enough for most construction projects
- Good balance of power and mobility
- Suitable for both urban and rural job sites
Large Excavators (25 to 40 tons)
Now we’re talking serious earthmoving power. These machines are built for heavy-duty work on large construction sites. If you’re regularly working on big commercial projects or major residential developments, a large excavator will help you get the job done efficiently.
Key benefits:
- Greater digging depth and power
- Higher productivity for big projects
- Can handle tougher soil conditions
Heavy Excavators (40+ tons)
You’ll find these powerhouses on major infrastructure projects, in mining operations, and anywhere else where moving massive amounts of earth is the order of the day. Unless you’re planning on reshaping mountains, you probably won’t need one of these behemoths for everyday construction work.
Key benefits:
- Maximum power and capacity
- Specialised attachments for specific large-scale tasks
- Unmatched productivity for the biggest jobs
With the right knowledge of excavator categories and sizes, you now have a better idea of which suits your project. But that doesn’t stop there! To make the best decision, there are other essentials to consider.
Key Features to Consider When Choosing an Excavator
If you’re looking to buy or rent the right excavator for your needs, understanding these key aspects will help you make an informed decision:
Operating Weight
This isn’t just about how heavy the machine is – it affects everything from stability to ground pressure and transportability. A heavier machine might offer more stability, but it could also be harder to move between job sites. Consider the types of projects you typically work on and the conditions of your usual work sites when evaluating operating weight.
Engine Power
More power usually means better performance, but it also often translates to higher fuel consumption. Thus, look for a balance that suits your needs.
If you’re regularly working with tough soil or need to lift heavy loads, you might want to prioritise power. For lighter work, a less powerful but more fuel-efficient engine might be the smarter choice.
Digging Depth and Reach
These specs determine how deep you can dig and how far you can reach. Think about the typical requirements of your projects. If you frequently need to dig deep foundations or reach across obstacles, pay close attention to these numbers.
Hydraulic System
The hydraulic system is the heart of your excavator’s performance. Look for advanced systems that offer smooth operation and good fuel efficiency. Features like regenerative hydraulics can improve cycle times, making your work more productive.
Fuel Efficiency and Emissions
Given the fact that the construction industry is responsible for 39% of the gross annual carbon emissions worldwide, fuel efficiency and low emissions are more important than ever. (3)
Therefore, look for machines with Tier 4 Final or Stage V engines for reduced emissions. Features like eco-modes and auto-idle can also help save fuel, reducing your operating costs and environmental impact.
Attachments and Versatility
What’s the use of having an excellent excavator only to have a poor-performing attachment?
The right attachments can turn your excavator into a multi-functional tool. So, when shopping for this machine, consider what attachments it might need and ensure that it’s compatible with a wide range. And here’s an extra tip: quick-coupler systems allow for easy attachment changes, saving time on the job site.

Making Your Decision
Choosing the best excavator is about balancing your needs, your budget, and the specifics of your typical projects. Remember, the ‘best’ excavator is the one that fits your exact requirements. So, take the time to consider all these factors, and you’ll be well on your way to making an informed decision that will benefit your construction business for years to come.
