10 of the World's Biggest Excavators
In an industry that's all about the largest, heaviest, most powerful machines out there -- we have to ask: who makes the biggest excavator in the world?
#1 Caterpillar 6090 FS
2024's largest excavator in the world is the Caterpillar 6090 FS.
The Caterpillar 6090 FS is not just one of the world's biggest excavators, it is the world's biggest hydraulic excavator. This hefty piece of machinery is built in the United States and boasts an operational weight of 242,9494 pounds! The Caterpillar 6090 FS further delivers a powerful engine rating of 4,500 horsepower. This machine can handle some massive loading shovel bucket capacity.
We can't say we're surprised that a Caterpillar excavator holds the number-one spot. For context, the largest caterpillar dump truck has a gross operating weight of 1,375,000 pounds. Now that's one massive operational weight, and yet two of Caterpillar's 797 Series dump trucks hit that hefty rank. You have to wonder what kind of construction sites wield a combination of Caterpillar's excavator and dump truck power.
One of the most exceptional Cat 6090 FS features is the automatic roll-back limiter. A roll-back limiter prevents spillage while supporting maximum bucket capacity.
The world's largest excavator also provides impressive boom speed, a reinforced undercarriage, and crawler components that protect against wear and tear.
But we must give credit where credit's due: the biggest excavator in the world is modeled after the Bucyrus RH400. The Bucyrus RH400 previously held the number-one spot but is now (quite respectably) the second-largest hydraulic excavator of all time.

#2 Bucyrus RH400
This design was part of a long line of acquisitions that determined who controlled the record-breaking excavator. The industry first called this excavator the Terex O&K RH400 before Terex was acquired by Bucyrus. It later evolved into the incredible Caterpillar 6090 FS after Caterpillar acquired Bucyrus in 2010. This model quickly became a core part of Caterpillar's line of mining equipment for its maximum digging force.
The Bucyrus RH400, once the world's biggest hydraulic excavator, has an operating weight of approximately 2,160,510 pounds with killer 4,500 horsepower.
The Bucyrus RH has a TriPower front shovel and backhoe attachment, an independent oil-cooling system, and electronic-hydraulic servo control. It can work for both shovel loading and backhoe operations as a front-shovel excavator.
Pro tip: Timeless Terex mining division equipment can still be purchased here at Boom & Bucket.

What do you mean by "Operating Weight?"
An excavator's operating weight (or operational weight) is the total weight of the machine while it's in use. That includes fuel, the human operator, the engine, bucket capacity, and attachments.
Another important metric to know in addition to a mining excavator's operational weight is its breakout force.
What do you mean by "Breakout Force"?
Breakout force means the level of force the heavy machinery can exert against its cutting edge.
One can maximize breakout shovel forces by increasing hydraulic power and using a narrow, sturdy shovel.
The last excavator consideration you will want to wrap your head around is its shovel and backhoe capacity.
What do you mean by "Backhoe and Shovel Bucket Capacity?"
A shovel bucket pushes material away from the excavator, while a backhoe bucket pulls material inward.
A shovel bucket is typically used on the biggest excavators (like the world's largest excavators found on the list below), while a backhoe is more commonly seen on small-to-mid frame excavators. All excavators are compatible with shovel and backhoe attachments. Bucket capacity ranges across manufacturers and models. It is wise to consult a bucket capacity size chart to determine the ideal bucket capacity for your specific excavator operating weight and the task at hand.
In Need of A Used Excavator for Your Next Project?
If you're looking for a used excavator, you've come to the right place. While the world's biggest excavators are some mammoth machines, they're probably bigger than the excavator size you need --- most standard excavators in the world have operating weights in the range of 10 to 45 tons. No matter what your project is, Boom & Bucket can help you find the right equipment for the job.
