Before You Rent or Buy a Potain Tower Crane: A 7-Step Equipment Checklist

I’m the person contractors call when a “minor oversight” turns into an emergency. A missing pin. A concrete bucket that doesn’t fit the hook. A crane booked for the wrong radius. In my role coordinating rush equipment logistics for crane dealers and rental companies, I’ve handled more than 200 emergency orders in six years — same-day truck runs, overnight freight, and more than a few “the pour is at 6:00 a.m. and we just realized…” phone calls.

Here’s the thing: most of those emergencies were never sudden. They were predictable. It took me a few years and a lot of invoices to see the pattern, but nearly every crisis traced back to a checkbox nobody ticked early enough.

That’s why I put together this checklist. It’s the one I walk clients through before they sign a purchase order or rental agreement for a Potain tower crane. It won’t replace your engineer’s lifting plan or your site safety review. It will, however, keep you from making the kind of call I get.

Seven steps. Most are just conversations — with a dealer, an electrician, a trucking company, and your own team. It takes a morning. The alternative is usually a lot more expensive.

1. Define the lift before you define the crane

Most project requests start with the crane. “We need Potain tower cranes for rent — something like an MCT 85, maybe bigger.” That’s backwards. The crane is an answer. The load is the question.

Before you call a dealer, sit down with the drawings and write down three numbers:

• The heaviest single lift on the job. If you’re placing concrete with the crane, that means a loaded concrete bucket, not just the steel beam.
• The radius where that heaviest lift happens. A crane that handles 6 tons at 20 meters might handle only 3 tons at 50 meters. The load chart is what tells you which one you’re actually renting.
• The hook height you need — and whether the crane has to be climbed or tied into the structure as the building rises.

I’m not a structural engineer, so I won’t pretend to read load charts for you. What I can tell you from an equipment-availability perspective is this: don’t book a crane because it’s available and then hope the lifts fit. The wrong crane is worse than no crane. It gives you a false sense of progress until the day somebody actually tries to lift something.

2. Run the total-cost math before you buy or rent

Potain cranes for sale make sense when you have a steady pipeline of projects that will keep the asset working. Potain tower cranes for rent make sense when you need a crane for one job and don’t want to deal with ownership afterward. That part is straightforward. It’s the total-cost part that trips people up.

The sales price or the rental rate is just the headline number. If you’re buying, add delivery, foundation or ballast work, erection and dismantling, commissioning, spare parts, and storage between projects. If you’re renting, ask exactly what the rate includes. Many rental quotes don’t include delivery, setup, climbing sequences, or overtime if the erection runs long.

I’ll say it plainly: the lowest quoted price is rarely the lowest total cost. I’ve watched contractors pay $8,000 in unexpected fees to save $5,000 on a rental quote. That math never works out in your favor.

3. Verify what “complete” actually means

A tower crane isn’t a single machine. It’s a system: tower sections, jib sections, counter-jib, counterweights, hook block, trolley, safety devices, climbing equipment, and enough fasteners to make your head spin. When a rental agreement says “complete crane,” that word means whatever the dealer’s configuration list says it means. Read that list before the crane is loaded on trucks, not after.

Potain offers several crane families — the MCT range, the MDT series, the MR luffing-jib models — and each has a different component list and erection process. A complete setup for one project isn’t necessarily complete for another.

Ask your dealer for the configuration list in writing. Confirm every major component and ask for the erection documentation ahead of time. That 30-minute phone call has saved my clients more times than I can count.

Last fall one client called two days before a scheduled pour because the hook block wasn’t in the shipment. Rush freight, an extra crane-day, and a very stressful Monday. It cost them about $5,000. The check that would have caught it would have taken 30 seconds during pre-delivery inventory.

4. Put the bucket in the load chart

This is the one that gets ignored. Contractors will spend weeks calculating structural steel weights and then forget the bucket — literally.

If you’re placing concrete with a tower crane, the crane is lifting a concrete bucket. The bucket itself weighs hundreds of pounds empty. A yard of concrete runs about 4,000 pounds. Add them together and you have a load that needs to be in the crane’s load chart at the exact radius where you’re placing concrete — not at the radius closest to the mast.

I know, it sounds too simple to skip. But I’ve taken the call: the crane is on site, the concrete truck is waiting, and nobody verified the loaded bucket at the far corner of the slab. The crane physically can’t reach the pour point with a full bucket. That’s not a bucket problem. That’s a planning problem.

If you’re using a concrete pump instead of a crane-and-bucket operation, this step doesn’t apply. But if you’re not sure which method you’ll use, check the bucket anyway. Deciding later is exactly how these calls happen.

5. Plan the power — and let an electrician size the backup

I’m not an electrician, so I won’t pretend to size a generator. But I’ve watched enough crane startups to know where those problems live.

An electric tower crane runs on site power. If the site doesn’t have a reliable supply yet — or the main supply drops while the crane is holding a load — you’re not dealing with a scheduling problem. You’re dealing with a load hanging in the air and no way to move it.

A portable unit like a Westinghouse generator is great for keeping site lighting, tools, and water pumps running during an outage. That’s a sensible early-site investment. But a portable generator isn’t automatically capable of running a tower crane. If you need backup power for the crane itself, have an electrician calculate the actual requirements and spec the unit. Guessing is not acceptable here.

6. Match the support truck to the load

I still get asked, “What is a half ton truck?” — usually right before someone tries to use one for a pickup that needs a flatbed.

Here’s the short version: “half-ton” is a historical classification for light-duty pickup trucks, going back to when they were rated to carry about half a ton, or 1,000 pounds, of payload. Modern half-ton pickups like the Ford F-150, Ram 1500, and Chevrolet Silverado 1500 can carry much more than that, depending on how they’re built. The exact payload for a given truck is on the driver’s door jamb sticker.

For a crane project, a half-ton truck is fine for moving the site team, tools, and small parts. It is not for moving crane components, counterweight blocks, or long wire-rope drums. Those are flatbed or lowboy loads.

I once coordinated a parts pickup where the project manager said, “we’ll send our truck.” Their truck was a half-ton pickup. The component weighed about 4,800 pounds. It wasn’t close to fitting — in the bed or on the payload rating. We arranged a flatbed, paid extra for the delay, and whatever they saved on the original setup went out the window.

7. Build the emergency call list before you need it

This is the step everyone says they’ll do later. Later rarely comes.

When a crane is down or a part doesn’t show up, the clock runs in hours. You’ll want the dealer’s parts hotline, after-hours emergency contacts, the erection company, the electrician, and a trucking company that hauls heavy equipment. And don’t forget the person with spending authority. If every rush decision needs a two-day approval chain, a small problem becomes a big one while you wait.

Decide in advance how much can be approved for overnight freight without an extra sign-off. It sounds like an administrative detail. It’s actually one of the fastest ways to keep an emergency from getting worse.

What this checklist is really about

After enough late-night calls, I’ve come to believe that checklists are cheap insurance. The equipment side of a tower crane project is mostly verification: start with the load, confirm the package, count the bucket, sort out the power, send the right truck, and keep the emergency list handy in case life still happens.

I can only speak to the logistics side of a crane project. I’m not the engineer who approves the lifts, and I’m not the electrician who sizes the supply. But I’m the person who gets called at 10 p.m. when those details fall through the cracks. Thirty minutes of checking beats five days of correction. If this list helps you avoid that 10 p.m. call, then it’s done its job.
