I'm not a crane engineer. I'm the office administrator for a 42-person construction company, and I manage all plant hire and purchasing—roughly $2.8 million a year across 18 vendors. I report to operations and finance. If you want load charts, I'm the wrong person. If you want to know why a crane hire quote can grow by thousands of dollars after it's signed, I'm exactly the right person.
Potain's product page (manitowoc.com) lists the MDLT 1109 as a luffing-jib tower crane. But a spec sheet tells you what the crane can do. It doesn't tell you whether the rental agreement includes the counterweight, the mats, the access study, or the collection. That lesson took me a while to learn.
Actually, let me back up.
In January 2024, a site manager asked me to arrange a Potain MDLT 1109 tower crane for one of our jobs in Birmingham. That's a real request with a real spec, and the crane itself was the easy part.
How the Potain MDLT 1109 tower crane hire started
Our usual supplier had one available, but the quote was higher than a second supplier I knew from a previous project. I did the responsible-looking thing: I compared the two quotes line by line.
The trap was in the transport line. The usual supplier's quote included crane mats, delivery scheduling, and a site survey. The second supplier looked cheaper on paper but listed those same things as extras. I convinced myself we could save money by handling transport with a haulage company I'd used before. That was not smart.
The pivot: cheap transport that wasn't cheap
The haulage company quoted $2,000 less than the crane supplier's transport charge. I booked it. The driver arrived on the wrong day, on the wrong trailer, with no edge protection. The Potain crew stood by for nearly nine hours. That cost us $3,600 in waiting time and a reschedule fee. I remember standing in the car park at 6:40 p.m. listening to three voicemails about the same delay.
The crane was fine. My decision-making was not.
If I had spent five minutes verifying the delivery window and the trailer spec, I would have caught the problem before the truck left. That is the part of procurement that never shows up in a textbook: prevention is cheaper than correction.
The paddle attachment and the Crewe tractor
That same month, I made a smaller but dumber mistake.
A supervisor asked me to order a paddle attachment for the Crewe tractor. That's exactly how he wrote it: 'the Crewe tractor.' I knew the tractor sat at our Crewe depot, so I didn't ask which attachment, which model year, or which hitch fitting. I found a paddle attachment that looked close, ordered it, and told myself it was good enough.
It didn't fit. The supplier charged a 20% restocking fee plus return freight. The total cost of not asking one question was about $900.
That was the third time in two years that a missing specification cost us money. After the Crewe tractor mistake, I stopped trusting my memory and built a checklist. It sounds boring. It's also the cheapest insurance I've ever used.
What the checklist caught on a Potain HD 16C crane hire
In March 2024, we needed Potain HD 16C crane hire for a smaller concrete pour. I pulled out the checklist I'd made after the Crewe tractor mess. It was just a list of basic questions:
- Are delivery and collection both in the quote?
- Who provides crane mats, counterweight, and lifting gear?
- Is the site access plan confirmed in writing?
- What happens if the crane cannot reach the hook block on the first day?
Some of these felt like 'are you smarter than a fifth grader questions.' I felt silly asking them. But the answers were not obvious. The Potain HD 16C crane hire quote didn't include collection. It buried 'site study extra' on page three, under a section I almost missed. If I had trusted the headline price, we would have been about $2,400 over budget.
That's the difference between a good quote and a complete quote. The first number is never the whole truth.
What I do now
Before I approve any equipment rental or purchase, I ask the dumb questions. 'Why do you need this model? Who put that specification on the order? What happens to the site if the machine arrives a day late?' These are not actually dumb questions. They are the same questions a field engineer would ask before a lift.
I also refer to the model conditions from the Construction Plant-hire Association (cpa.uk.net). They are not exciting, but they make clear who handles access, unloading, and ground conditions. I do not mean that every rental company is hiding something. The problem is usually not bad intent. It's incomplete instructions.
I've got mixed feelings about the whole system. Part of me wants to believe one trusted supplier solves all of this. Another part knows that even good suppliers make mistakes—and that my mistakes, not theirs, were the expensive ones. Redundancy is not about playing vendors against each other. It's about having a second pair of eyes on the spec before money moves.
I'm not a procurement consultant, so I won't pretend this is a complete framework. I can only tell you what works for a construction company without a dedicated purchasing department: a simple checklist, a second review for any order over $10,000, and a rule that no verbal request goes to a supplier in writing until the equipment model is confirmed.
The bottom line
If someone asks you to arrange a Potain MDLT 1109 tower crane, do not just nod. Ask for the job number, the site address, the required jib length, the supplier's reference, and the configuration in writing. The same goes for Potain HD 16C crane hire or anything else with a delivery date and a rental period.
Five minutes of verification beats five days of correction.
That line is not from a textbook. It's from a spreadsheet of my own mistakes. The gap between a cheap quote and the final cost is filled by details no one bothered to confirm. So slow down, ask the fifth-grade questions, and get the answer in writing. It takes fifteen minutes. It's a lot cheaper than watching a wrong paddle attachment come back on a pallet with a restocking fee.
