What a 30–40 ton machine is for
The 330 sits above the 20-ton class. That extra size is useful when the job is built around volume: quarry loading, mass earthworks, large site preparation, road construction and heavy trenching. It is not automatically better for every job. A bigger machine costs more to move, needs a bigger low-bed or a different shipping plan, and can be too large for tight sites.
Before you compare the $33,000 price with a 320D, ask what the machine will actually do. If the work is residential digging and utility trenches, a 20-ton machine may be the better fit. If the work is production loading and the site can take a 30–40 ton machine, the 330 is the right class.
Job fit, not model prestige
| Work | Is the 330 a fit? | Why |
|---|---|---|
| Quarry loading | Yes | Built for repeated high-volume loading |
| Mass earthworks | Yes | Higher capacity per cycle than a 20-ton unit |
| Road construction | Often | Depends on haul road and transport access |
| Residential digging | Rarely | Too large and too expensive to move for small jobs |
| Utility trenches | Usually no | A 13–20 ton machine is more practical |
This is a class decision, not a brand decision. The 330 is a tool for a certain size of work. If the work is smaller, the 320D or the 313D2GC may deliver a better return.
Grade A and 7,353 hours
The listing says Grade A. That is the highest condition band in the listing, but it is still not a warranty. On a 2021 machine with 7,353 hours, ask the same questions you would ask on any used unit:
- Cold-start video: smoke, blow-by, idle stability.
- Hydraulic cycle: boom, arm, bucket and travel; watch for drift and noise.
- Undercarriage: shoes, links, rollers, idlers and sprockets.
- Pins and bushes: bucket, arm and boom play.
- Cab and electronics: monitor, warning lights, joysticks, wiring.
- Structure: boom, arm, frame and counterweight photos.
The transport line is bigger than on a 20-ton unit
A 30–40 ton machine is not a container-friendly size in the same way as a 20-ton unit. The loading plan may involve a flat rack, a break-bulk vessel or a different port. That changes the freight quote, the inland transport and the schedule.
Ask for the port and the loading method for this unit before you compare it with a 20-ton machine. A $33,000 FOB price with a heavier freight bill is not the same landed cost as a 20-ton unit. The freight quote is part of the machine decision.
Why there is only one unit
We hold one 330 at the moment. That is not a marketing line; it changes how you buy. There is no second unit of the same year and grade to compare against. If you need two matching machines, you may have to wait for another unit or accept a different year or grade.
For a buyer who needs one machine, one unit is enough. For a dealer building a package, it may not be. Ask for the current stock list before you plan around this unit.
Who this unit fits
This 2021 CAT 330 fits a contractor or dealer who needs a 30–40 ton machine for production work and can handle the transport and site access. It also fits a buyer who wants a newer, Grade A unit and is prepared to pay $33,000 for it.
It is not the right choice for a small site, a tight budget, or a buyer who needs multiple matching units. In those cases, compare the 20-ton 320D or the 13-ton 313D2GC and keep the transport cost lower.
A quarry loading cycle, from the operator’s seat
A 30–40 ton machine earns its keep in the cycle: swing loaded, dump, return, repeat. The cycle is where the size advantage shows up — not in a spec sheet, but in how many passes it takes to fill a truck and how stable the machine feels at the face.
When you inspect this unit, ask for a video that shows a full cycle, not just the boom moving. Watch the swing, the dump, the return and the travel. Listen for hydraulic noise and look for hesitation. A machine that cycles smoothly is more valuable than one that only starts and idles.
If the machine will work at a quarry face, also ask about the bucket and the pins. The bucket is a wear item; the pins and bushes are the joints that take the load. Photos of both are part of the inspection, not an optional extra.
Transport checklist for a 30–40 ton unit
Before you commit, ask five transport questions: which port, which loading method, what inland transport is needed, what permits or route restrictions apply at destination, and what the freight quote includes. A 30–40 ton machine is not a container-friendly unit in the same way as a 20-ton machine, so the transport plan is part of the purchase.
If the seller cannot answer those questions clearly, ask for a written quote. A vague freight estimate is not a plan.
What to ask about a single unit
When there is only one unit, the questions change. Ask for the date of the video, the photo set and the inspection report, so you know the evidence is current. Ask for a photo of the hour meter and the stock plate. Ask for a written FOB and freight quote, not a verbal estimate.
Also ask how long the unit can be held while you arrange inspection or payment. A single unit can sell while you are still comparing. If the machine is right, move on the evidence, not on the listing alone.
Questions buyers ask

Do you have another 330?
Only one unit of this model at the moment. Ask for the current stock list if you need a second machine.
One unit, one inspection.
Ask for the cold-start video, undercarriage photos and the freight quote for exy-cate330-197. If the machine fits the job, the next step is the inspection, not another listing.
