Potain MDT 389 L16: An Admin Buyer's FAQ on Tower Cranes & Budgets

When I first took over equipment purchasing for our mid-sized construction firm in 2020, I assumed buying a tower crane was just like ordering office supplies—you find the lowest price, send a PO, and it shows up. Three years and a few hard lessons later (including an $800 mistake on specification verification), I know better. This FAQ covers the questions I had when we needed to find a potain crane for a Utah project, and the answers I found.

Frequently Asked Questions

What is the Potain MDT 389 L16 tower crane, and is it right for my job?

The Potain MDT 389 L16 is a flat-top tower crane, part of their topless range. It's designed for high lifting capacities in tight spaces. For us, the key specs were its maximum load of 16 tons and a jib length up to 80 meters. It’s a popular choice for larger infrastructure or commercial projects. Whether it's right for you depends on your site layout and lift requirements. You’ll want to check the load charts carefully—I learned to do that after skipping this step and getting a unit that was too underpowered for our steel erection phase (note to self: never trust a verbal confirmation).

Why would I need a Potain luffing tower crane in Utah?

A potain luffing tower crane has a jib that can be raised and lowered, unlike a standard saddle jib. This makes it ideal for confined urban sites in cities like Salt Lake City, where you might have obstacles or need to avoid swinging over adjacent properties. On a recent project requiring a potain luffing tower crane utah for a downtown high-rise, the luffing mechanism was critical. The upside—getting the crane in and out without closing a street—was huge. The risk was the higher rental rate. I kept asking myself: is the premium worth avoiding a road closure permit? For that site, yes. I only believed in the value of luffing cranes after ignoring advice on a previous project and dealing with a two-day street closure fee that ate our margin.

Are 'bob crane' and 'dewallt drill' related to my tower crane purchase?

Not directly, but they illustrate a common trap in procurement. A bob crane (likely a misspelling of a ‘bobcat’ brand or a small crawler) and a dewalt drill are small tools. It’s easy to focus on the $800 cost of a dewallt drill for the crew and negotiate hard on it, while overlooking the $150,000 annual lease for a potain mdt 389 l16. When I first started, I wasted hours haggling over small-ticket items. A supplier who couldn't provide proper invoicing for our rental of two potain units cost us $2,400 in rejected accounting expenses. Now, I focus on the big-ticket items and their total cost of ownership.

How do I budget for a Potain tower crane rental?

Budgeting isn't just the monthly rental rate. You need to factor in delivery, erection, dismantling, maintenance, and operator costs. For our potain rental, the base price was competitive, but the ‘cheap’ quote ended up costing 15% more when I added the mandatory 5-year load test the vendor conveniently forgot to mention in their initial email. Always get an all-in quote. I usually ask for a breakdown line by line. The certainty of a fixed, all-in price is often worth more than a lower base rate with ‘variable’ charges. Put another way: a low headline number is useless if the final invoice is unpredictable.

Can I use a can crusher to cut costs on my project site?

Ha! No. A can crusher is for recycling cans in a break room. This question highlights how easy it is to misdirect procurement searches. If you’re searching for ‘can crusher’ and ‘tower crane’ in the same session, it’s a good sign you need to refine your keywords. It’s also a reminder to check the specifications of your vendors. The most frustrating part of my job: seeing the wrong MRO items ordered because someone didn't read the specs. Standard print resolution for our site plans is 300 DPI (i.e., sharp enough to read the load charts without a magnifying glass). We don't need a can crusher—we need a reliable crane.

What's the one question I should ask before buying or renting a Potain crane?

Ask about the service and parts network. A potain in the field is only as good as the support behind it. We nearly lost a week of work because we didn't verify parts availability for a specific potain model. The supplier had the manual (great), but the required hydraulic filter wasn't in stock locally. You’d think written contracts would specify spare parts availability, but they often don’t. Check the lead time for critical spare parts. And always ask for a reliable contact number for after-hours tech support. The total cost of ownership (i.e., not just the crane price but all costs of downtime) is the only metric that matters.
