When I first started coordinating crane fleet maintenance, I assumed the answer to “who should inspect a crane?” was obvious: the manufacturer’s certified technician. Period.
A few years and one very expensive misdiagnosis later, I realized it’s not that simple.
The truth is, the right person to inspect a crane depends entirely on your specific situation—what kind of crane you’re dealing with, how it’s being used, and what the stakes are. There’s no universal answer, and anyone who tells you otherwise probably sells inspection services.
Here’s how I break it down for our clients. Which scenario fits you?
This is the highest-stakes scenario. You’re about to drop six figures—or more—on a piece of equipment that could have hidden fatigue cracks, worn-out swing circles, or undocumented repairs.
Who should inspect it? A third-party specialist who does nothing but crane inspections. Not the dealer selling it. Not your in-house mechanic who’s great with telehandlers. Someone who knows exactly where to look for stress fractures on a lattice boom and has the ultrasonic testing gear to back it up.
In March 2024, we had a client who found a great deal on a used crane. Their own mechanic gave it a thumbs-up after a visual walkaround. They almost closed the deal. I recommended a third-party inspection. Turned out the main boom had a crack that was invisible to the naked eye but showed up clearly on an MPI test. The repair cost would have eaten their entire savings on the purchase price.
What to look for in an inspector:
If I’m honest, I’m not sure why more buyers skip this step. My best guess is they’re trying to save a few thousand dollars on a six-figure purchase. That math never works out.
Different game entirely. You’re not buying the machine, so long-term structural integrity isn’t your primary concern. What you need to know is: is this specific crane safe to operate tomorrow?
Who should inspect it? The rental company’s qualified technician, with you or your site supervisor present for a joint walkaround.
Why involve yourself? Because you’re the one who will be liable if something goes wrong on your site. The rental company’s inspection protects them. Your inspection—even if it’s just a visual check of the load chart, cables, and outriggers—protects you.
Last quarter, we had three rental crane incidents across our client base. Two were caught during joint inspections before any lifting began. One wasn’t—and that one caused a minor injury and a week of downtime.
To be fair, most rental companies do thorough pre-rental inspections. But I’ve seen enough cases where a rental unit arrives with incorrect rigging or a missing manual to never skip the joint walkaround.
Looking back, I should have been more insistent about this earlier in my career. At the time, I trusted that if the rental company said it was good, it was good. Not always true.
This is where most mistakes happen. Your own crane on your own site, just moving a piece of equipment from one side of the yard to the other. Who needs an inspection for that?
You do. And the person who should do it is… you. Or more specifically, the designated operator who is trained to perform a pre-operation inspection per OSHA standards.
The key word is “trained.” OSHA requires that cranes be inspected by a competent person—someone who can identify existing and predictable hazards. That person doesn’t need to be a third-party specialist, but they do need:
Here’s the counterintuitive part: for routine in-yard lifts, hiring an external inspector might be less effective than having a trained operator do a thorough pre-op check. Why? Because your operator sees the crane every day. They notice when something sounds different or feels off. An external inspector is looking at a snapshot; your operator sees the whole history.
If your operator isn’t doing this daily, that’s a bigger problem than who to call for an inspection.
Still unsure? Here’s a quick decision guide:
There’s no single right answer, but there’s definitely a wrong one: letting anyone who isn’t qualified or doesn’t understand the context make the call. The cost of that mistake isn’t just a repair bill. It’s downtime. It’s liability. It’s trust.
Approved the third-party inspection fee last month and immediately wondered if we could have gotten away with a cheaper option. Didn’t relax until the report came back clean. Simple as that.
