Tower Crane Distributor Buying Guide: 9 Checks Before You Buy a Potain Crane

Who This Checklist Is For

If you're sourcing a Potain crane, a Potain self-erecting crane, or comparing a mobile crane supplier and a ton crane distributor for an upcoming project, this checklist is for you. I'm a quality and brand compliance manager at a crane and lifting equipment distributor. I review every crane and parts order before it reaches customers—roughly 200+ line items a year. In 2024, I rejected about 14% of first deliveries due to documentation gaps, spec mismatches, or damaged components.

When I first started vetting crane suppliers, I assumed the lowest quote was the best choice. Three project delays later, I learned that total cost includes documentation, parts availability, and local support.

This list has nine steps. Work through them in order. Don't skip the boring ones.

1. Define the Lift Before You Call a Distributor

Don't start with 'What do you have in stock?' Start with the lift plan. What's the max load? Radius? Hook height? Ground conditions? If you need a Potain self-erecting crane, you're probably working on a tighter site with faster setup. If you need a top-slewing tower crane, you're likely looking at a longer project with higher capacity. If you need mobility, a mobile crane supplier might be part of the package. Mixing these up wastes everyone's time.

Write down the capacity in tons, the reach, and the duty cycle. Then ask the distributor to match the model to the plan. Not the other way around.

2. Verify the Distributor Is Authorized for Potain

Ask for written confirmation of what they support. New Potain tower cranes? Used equipment? Rentals? OEM parts? A Potain dealer should be able to show model coverage, serial number ranges, and parts diagrams. If they can't, that's a red flag.

In our Q1 2024 audit, we found two orders where the parts were listed as Potain-compatible but had no traceable part number. We rejected both. The vendor claimed it was 'within industry standard.' Not good enough. Now every contract includes OEM or documented equivalent requirements.

3. Request the Documentation Packet Before Pricing

Documentation is not paperwork. It's the difference between a crane you can legally operate and a liability. Ask for:

• Load charts for the exact configuration
• Maintenance and inspection logs
• Serial number and model verification
• OEM parts traceability for critical components
• Compliance references for OSHA 1926.1400 and ANSI/ASME B30.3 or B30.5 as applicable

If the load chart is missing a revision, the crane's capacity may be wrong. That's not a small issue. It's a stop-work issue.

4. Check Parts Coverage and Traceability

Potain crane parts are not commodities. Counterfeit or undocumented parts can fail early and void warranties. Ask how the distributor sources parts. Can they provide Potain part numbers? Do they have a process for verifying critical components like brakes, wire rope, and limit switches?

This worked for us, but we're a mid-size dealer with a stocked parts department in Utah. If you're buying a single part for an old model, your mileage may vary. Some specialty parts may take longer. Plan for that.

5. Confirm Local Support and Service Radius

If you're in Utah, local support is a real advantage. Ask about service techs, response times, and spare parts stock. A distributor three states away might save you 5% on the invoice, but cost you two weeks of downtime. That math rarely works.

I can only speak to our region. If you're outside Utah, the calculus might be different. But the principle holds: find out who will actually show up when the crane stops.

6. Inspect Used Equipment Like You'll Reject It

Used cranes can be great value. They can also be a money pit. Inspect structure, welds, wire rope, brakes, electrical systems, and hour meters. Compare the serial number to the maintenance log. Look for undocumented repairs.

In 2023, I rejected about 12% of used crane first deliveries due to weld repairs that weren't in the file. Not ideal. But workable if you budget for the fix. Better to know before delivery.

If you're buying a used Potain self-erecting crane, pay extra attention to the erection mechanism and the base ballast. Those are common problem areas.

7. Nail Down Commercial Terms in Writing

Get delivery, commissioning, training, and warranty terms in writing. Be skeptical of any supplier that promises every model will arrive immediately. No one can do that. Ask for a schedule with dates and responsibilities.

Warranty varies by new, used, rental, and parts. Get the actual coverage period, exclusions, and who performs the work. Don't assume. Ask.

8. Plan for Commissioning and Training

A tower crane is not a plug-and-play tool. You need erection, commissioning, load testing, and operator training. Who does it? What's the cost? Is it included? If the distributor can't explain the process, they're probably not the right partner for a tower crane.

For a mobile crane, the checklist is shorter—but you still need inspection and operator familiarization. A ton crane distributor should be able to walk you through it.

9. Do a Pre-Delivery Audit at the Yard

This is the step most buyers skip. Go to the yard. Check the serial numbers. Verify the load chart. Open the control panel. Ask for the inspection report. Take photos. If something doesn't match the paperwork, stop the delivery.

That one yard visit has saved us from at least three bad deliveries. It's worth the drive.

Common Mistakes to Avoid

• Don't rely on verbal specs. Get them in writing.
• Don't assume a low quote includes erection, commissioning, or training.
• Don't mix mobile crane requirements with tower crane requirements.
• Don't accept undocumented parts as 'equivalent.'
• Don't skip the pre-delivery audit. Ever.

A Note on Industry Evolution

What was best practice in 2020 may not apply in 2025. Digital load charts, telematics, and parts traceability have changed the game. The fundamentals—capacity, condition, documentation—haven't changed. But the execution has transformed.

If you're using a checklist from five years ago, update it. Add digital verification. Add parts traceability. Add service response times. The old stuff still matters. The new stuff matters more than it used to.

Final Check

Before you sign, ask one more question: 'If this crane goes down in three months, what happens next?' If the answer is vague, keep looking. If it's specific—with names, parts, and timelines—you're probably in good hands.
