Look, I'm not going to pretend I knew what I was doing when we took delivery of our first Potain HDT80 in Utah back in 2019. I had the brochures, the spec sheet, and a lot of confidence. What I didn't have was a proper pre-installation checklist. That mistake cost us roughly $4,000 and two weeks of delay.
This isn't a theoretical piece. It's a list of three specific, painful errors I made, and the simple checks I now do to avoid them. If you're about to bring in a Potain HDT80—or any similar flat-top, really—this is the checklist I wish someone had handed me.
Mistake #1: The Assumption That 'Standard Soil' Was Universal
Here's the thing: the HDT80 is a solid crane. Potain tower cranes are built to handle serious loads. But I assumed the soil conditions at our Utah site were 'standard.' I didn't verify. Turned out 'standard' for the crane's foundation plan meant a bearing capacity of 3,000 psf. Our site had 2,200 psf in places.
What I mean is that I took the generic foundation design from the manual and ran with it. I didn't consider the specific soil report for that plot in Utah. We poured the base, cured it, and during the first load test, we saw micro-cracks. The engineer flagged it immediately.
The fix: Now, I have a hard rule. Before any potain tower crane arrives, we get a geotechnical report specific to the footprint. We send it to Potain's engineering team or a local PE. It adds two weeks to the timeline, but it saves you the $2,000+ in concrete and rework we spent.
I assumed 'same specifications' meant identical results across vendors. Didn't verify. Turned out each had slightly different interpretations of the load-bearing requirements.
Mistake #2: Forgetting About the Tail Swing Radius
This was the stupid one. I was so focused on the jib length and the lift capacity that I completely glossed over the tail swing radius of the HDT80. On paper, the radius is manageable. In reality, our laydown area was tight. We had a container and a welding rig set up about 12 feet behind the crane's pivot point. The HDT80's counter-jib needs about 10 feet of clearance. On a windy day in September 2022, the counter-jib clipped a safety light on top of the container during a slow slew.
No one was hurt. But the light was destroyed, and we had to stop operations for a full day while safety did an incident review. The embarrassment was worse than the cost.
The fix: My checklist now has a specific step labeled 'Tail Swing.' I take a tape measure and tape out the full circle of the counter-jib radius + 3 feet of safety buffer. I literally walk the circle. If anything is inside that line, it moves. It feels basic, but it's the most common oversight I see.
Pro tip from my third mistake: This is especially critical for luffing jib models like the Potain MR series, but don't let the rigid jib of the HDT80 fool you—the tail swing is real and unforgiving.
Mistake #3: Ignoring the 'Crane Club NYC' Mentality (The Human Error Factor)
Okay, this one sounds weird, but bear with me. There's a group of crane operators and rental managers in the New York area that informally call themselves the 'Crane Club NYC.' I'm not a member; I work in Utah. But I started following some of their online forums. What I learned is that the biggest failure point isn't the iron—it's the communication between the crane operator and the erection crew.
For the HDT80's installation, we had a new operator who had run a Potain HDT80 before, but never on a site with this specific configuration. I assumed he'd figure out the kinks. He didn't. On the second day of erecting, we had a near-miss where a signal was misinterpreted. The boom section landed hard. No damage to the crane, but the crew was shaken.
The fix: Now, 48 hours before any potain tower cranes are assembled, I mandate a 'pre-erect meeting.' This is a meeting where the operator, the rigger, the foreman, and the safety officer walk through the entire erection sequence—step by step—without moving a single piece of steel. We use the Potain manuals, we identify hand signals, and we clarify who is in charge of what. It takes two hours. It has prevented at least three major miscommunications since 2023.
So, bottom line: I'd rather spend 10 minutes explaining a tail swing radius than deal with a smashed light or a near-miss. An informed customer—or in this case, an informed team—asks better questions and moves faster. That's the real lesson from our Potain HDT80 in Utah fiasco.
One more thing. I see people comparing a heron vs crane for site walkways. Don't mix those analogies with your actual crane setup. Focus on the iron. Focus on the soil. Focus on the tail swing. And for god's sake, have the meeting.
