How to Choose Used Cranes for Wholesale: What I Check Before a Potain Crane Ships

2026-08-20 · Charlotte Avery

I'm the quality compliance manager for a crane supply operation in Utah. I review every machine before it reaches a customer—roughly 130 units a year. In 2025, I rejected about 9% of first deliveries. Not because the cranes looked broken. Because the paperwork didn't match the machine.

Here's my blunt take: most used crane buyers start with the wrong question. They ask, "What's the price?" or "How many hours?" I'd rather ask, "Can this machine be verified from serial number to load chart to service history?" If not, you're not buying a crane. You're buying someone else's problem.

I've reviewed maybe 500 units over the last five years. Actually, 480-ish, if I'm being precise. Every one of those taught me the same lesson: the spec sheet is not the crane.

Start With Evidence, Not Specifications

Take crawler crane specifications. A listing might say "80-ton crawler, 3,200 hours, nice condition." That's three data points. None of them confirm the machine's actual configuration. I've seen the same model arrive with two different boom lengths, a counterweight package that didn't match the load chart, and a hook block rated below the main winch. The listing wasn't a lie. It just wasn't complete.

Most crawler crane load charts are based on the manufacturer's certified configuration under standards like ASME B30.5. If the counterweight and boom arrangement on the machine don't match the chart, that chart is not valid for the unit sitting in front of you.

The same logic applies to overhead crane sourcing. You're not walking around tracks and a boom; you're comparing duty cycles, hoist classifications, and service factors. A 10-ton overhead crane isn't defined by "10 tons." It's defined by the CMAA duty class, the motor duty rating, and whether the runway allows for the actual lift height. If those don't line up, the capacity number means almost nothing.

For Potain tower cranes, the same principle matters even more, because tower cranes are modular. A Potain MCT85 configured with a 50-meter jib is a different machine than one with a 45-meter jib, even though the model number is identical. A used Potain crane with missing sections, a mismatched trolley, or a slew ring without serial numbers is not a bargain. It's a parts chase.

Parts Supply Is the Real Brand Promise

I have a bias for Potain, but not the kind that comes from a logo. It comes from watching machines sit idle while buyers wait for parts. Every crane eventually needs something—limit switches, brake pads, hydraulic cartridges, control board updates. The question is not whether a used crane will need a part. The question is whether you can get the correct part within a week, with drawings and a serial number match.

That's why a Potain dealer and parts supply matters more than the machine's paint condition. We've had MDT 178 and HDT80 units in Utah that needed components sourced from multiple countries. Local support means someone can walk out to the actual crane, look at the configuration, and confirm the part before you spend money on shipping.

If you're buying from a dealer that can't show you a parts pipeline, you're not buying wholesale. You're buying a lottery ticket.

What I Actually Check Before a Crane Ships

I don't trust any incoming machine until I verify these four things:

  • Serial number lineage. Is the main structure's serial number consistent across the title, registration, and maintenance records? If the hoist or slew ring has a different serial, that's normal. No documentation at all is not normal.
  • Configuration against the original drawing. Does the current jib length, counterweight, and hook block match a real Potain configuration? If not, the load chart might be invalid.
  • Inspection stamps that tell a story. A machine with annual inspection records from the same region is easier to verify than one with "available on request."
  • Final load test documentation. If the seller can't produce a recent load test certificate, I treat the crane as untested until proof arrives.

When I implemented this verification protocol in 2022, our customers didn't notice right away. They noticed later, when they didn't get stuck waiting for a part that didn't exist.

The Wholesale Trap

"How to choose used crane for wholesale" is a different question than how to choose one crane for a single project. Wholesale buyers are building a pipeline. They need consistency across multiple machines, not just one good deal.

I've seen a buyer take dozens of units that all looked similar on paper. When the first machine arrived, the tower sections didn't match the second machine, the controllers were different generations, and the parts manuals covered two out of six configurations. The deal was still cheap. The support costs weren't.

"We're getting these at wholesale prices; we can't be picky."

I hear that a lot. I have mixed feelings about it. On one hand, wholesale margins are real, and you can't push every detail without losing a deal. On the other, the cost gap between a clean machine and a "deal" disappears the first time you need a part shipped overnight for a downtime event.

Deal With the Objection: "Price Is the Deciding Factor"

Look, I'm not saying price doesn't matter. It does. A machine's price needs to fit the project economics, especially in wholesale transactions where the margin is the whole reason you're buying.

But here's the thing: price is only the first filter. The cheapest machine with the wrong configuration is more expensive than the right machine at a fair price. That's not a cliché. It's the difference between a crane that makes money and a crane that burns it. If you're buying a used crane for wholesale, apply a "verification cost" to every listing. What would it take to confirm the serial numbers, source the missing parts, and re-certify the load chart? That total, not the sticker price, is the real number.

Honestly, I'm not sure why some dealers resist showing service stamps. My best guess is that the history is spread across multiple previous owners, and no one wants to pay for a full traceability report. If someone has a better explanation, I'd love to hear it.

Your Crane Is Your First Impression

The most frustrating part of my job isn't finding defects. It's watching a buyer fall in love with a low price and then act surprised when the documentation doesn't support the machine's stated configuration. You'd think a 30-minute pre-purchase review would be standard. It isn't.

That quality issue cost us a $22,000 redo once, and it delayed a client's schedule by three weeks. The seller claimed everything was "within industry standard." We rejected the batch anyway. Now every contract we sign includes configuration verification before payment.

I'll say it again, because it's the whole point: the crane you choose is the first impression your company makes at the jobsite. A machine that shows up with mismatched components, missing paperwork, or an unverifiable load chart tells your customer more than any brochure ever will.

This is accurate as of my inspection practices through early 2026. The used crane market changes fast, so verify current pricing, model availability, and import requirements before you budget.

Buy the evidence. Buy the parts support. Buy the crane that matches its own documentation. If you do that, the wholesale price question will answer itself.
