Potain Crane Specs: A Six-Step Checklist From a Dealer Who's Made the Mistakes

If you've ever ordered a Potain crane part and watched it arrive with the wrong bolt spacing, you know the feeling. I'm the parts and specifications coordinator at a Potain equipment dealer in Utah, and for the last eight years I've been the person who turns a customer's request into an actual order. I've personally made (and documented) 14 significant mistakes, totaling roughly $42,000 in wasted budget. Now I maintain our team's pre-order checklist.

This article is that checklist. It's not an engineering course. It's a practical, six-step process for anyone dealing with Potain tower cranes, mobile cranes, crawler cranes, and crane parts. Use it before you quote, before you order, and before you send a machine to a jobsite.

From the outside, crane procurement looks like matching a model number to a load chart. The reality is that serial numbers, configuration lists, transport dimensions, and compliance requirements decide whether a project succeeds.

Who This Checklist Is For

If you're a rental fleet manager, a contractor with a Potain crane on site, or a procurement person chasing crane truck specifications for a mobile crane, this applies to you. People assume a crane is a crane until a $3,200 pin doesn't fit. What they don't see is the hidden configuration data that wasn't captured on the purchase order.

The Six Steps, In Order

Run these in order. Skipping ahead is where mistakes happen. Here's the whole sequence:

1. Check the serial number first.
2. Map the actual configuration.
3. Validate crane truck specifications for the route and site.
4. Confirm the mobile crane compliance requirements.
5. Verify crawler crane OEM parts by part number.
6. Document and archive everything.

Step 1: Start With the Serial Number, Not the Model Stencil

The model name on a Potain crane is a starting point, not an answer. An HDT80 with a factory main-boom modification is not the same machine as another HDT80. A Potain dealer with access to factory drawings can pull the correct parts from the serial number tag (usually stamped into the mast section, not painted on the counterweight). Don't trust the painted model number on the counterweight; I've seen mismatched paint and swapped counterweights on leased cranes.

In October 2022, I ordered a slewing ring for an HDT80 based on the model stencil. It looked fine on my screen. The result came back with ten holes that were 2 mm off, because the crane had been modified under a factory service bulletin. $3,800, straight to the trash. That's when I learned a simple rule: the serial number is the only version of the truth.

Step 2: Map the Configuration That Actually Arrives

People assume the brochure configuration is the delivered configuration. What they don't see is how many cranes have had jib extensions, counterweights, hook blocks, and power units swapped over the years. For a Potain tower crane, check the tower sections, jib length, climbing system, and maximum tie-in spacing. For a truck crane or crawler, verify the carrier, the boom inserts, and the counterweight options.

This step matters more than the original purchase order. If you're working with a dealer, ask them to walk through the configuration with you. It's basically a quality gate. When we deliver a crane that matches the customer's lifting plan exactly, they trust us for the next job. When we deliver something close enough, we don't get a second call.

Step 3: Crane Truck Specifications Are Route Documents, Not Just Brochure Numbers

Crane truck specifications usually get reduced to GVW and maximum road speed. That's a mistake. The full file includes boom stowed length, overall height, tail swing, outrigger spread, axle loads, wheelbase, and curb weight with every counterweight and jib installed.

Why? Because the route to the jobsite is where mobile crane problems show up. I once saved $300 by skipping a route survey for a truck crane. The 'we'll deal with it on site' choice looked smart until we met a 12-foot bridge restriction. Permits, escorts, and a tree removal cost us $7,200. Net loss: $6,900, plus an angry customer.

If you are quoting a crane move, build the route check into the quote. It's cheaper to decline a job than to explain a crane that can't turn through an intersection.

Step 4: Confirm the Mobile Crane Compliance Requirements Before You Quote

Mobile crane compliance requirements are not a gray area, but they are a constantly changing list. In the United States, federal OSHA applies to cranes used in construction under 29 CFR 1926 Subpart CC. That standard covers operator qualification, signal persons, riggers, ground condition assessments, assembly/disassembly plans, and crane inspections. State plans can be stricter, and a few counties add their own rules. Verify current requirements at osha.gov before you promise anything to a customer.

Here's the part that's easy to ignore: compliance is a deliverable. In Q1 2024, we won a rental contract and then discovered the written assembly/disassembly plan for the luffing-jib crane was outdated. That mistake cost us a 3-day delay before the crane could spin a load. Idle time alone was $450 per day. The client didn't cancel, but our credibility took a hit.

I cannot stress this enough. A load chart is not a compliance document. An inspection report is not a permit. Check both before the crane leaves the yard.

Step 5: For Crawler Crane OEM Parts, Verify the Component Part Number

The term crawler crane OEM gets thrown around a lot. For a crawler crane, OEM doesn't mean same brand as the engine; it means a part supplied by the crane manufacturer, for a specific machine configuration. A track roller with the right outside diameter can still be wrong if the pin bore is different.

Last year, a customer asked for a crawler crane OEM track roller. We ordered by model and serial number, and the part still didn't fit, because the machine had an optional heavy-duty track frame that wasn't in the owner's manual. We caught it before install, but only because we asked for the component part number stamped into the old roller.

Rule: if the customer can't give you the part number, ask for a photo of the part and the nearby serial plate. Then have the dealer confirm it against the factory parts system. It takes five minutes and prevents a $1,500 mistake.

Step 6: Document and Archive Everything

This is the step almost everyone skips. You think you'll remember, but that machine gets moved, and the person who ordered it leaves for another job. Take photos of serial plates, record the physical dimensions of every part you order, and attach the manufacturer's drawing to the work order.

In our shop, we've caught 47 potential errors using this checklist in the past 18 months. Most were caught at the documentation stage, because someone noticed a part number mismatch before the order went to the supplier. The cost of documentation is zero. The cost of a wrong part is not.

Final Notes: What To Watch Out For

Here are the common mistakes I still see, and I include myself in that list:

• Don't trust a model name printed on a used crane. Serial numbers and factory drawings matter more.
• Don't treat compliance as an afterthought. Operator certs, inspection reports, and A/D plans are project prerequisites.
• Don't order crawler crane OEM parts without a component part number. Compatible is a sales word, not a quality word.
• Don't let budget become cheap in front of a customer. The $150 difference per component has translated into noticeably better client retention for us.

This checklist won't catch every mistake. Honestly, I still make new ones. But it will catch the common ones, and it will protect your reputation while you're building it. If you're a Potain dealer, a rental manager, or someone just asking 'is this crane the right one?' run the six steps before you order. Trust me on this one.
