If you've ever watched a rental crane sit idle for four hours because nobody could agree on who should inspect it, you know the feeling. That delay is a budget problem, not just a safety problem.
I'm a procurement manager at a mid-sized civil contractor. I've managed our equipment budget for six years—about $480,000 a year across a fleet of BOMAG roller compactors, excavators, one bucket truck, and a few engine hoists in the shop. I don't perform inspections, but I own the cost when they don't happen.
Who should inspect a crane? The short answer is a competent person. The more useful answer is: a named, trained, authorized person, acting before the machine is used, with a record that your accounting team can find. Here is the five-step checklist I use.
1. Name the competent person before the equipment arrives
OSHA's crane standard doesn't say the inspector has to be an outside engineer, and it doesn't say the operator is always the right choice. It says frequent inspections need a competent person. Under OSHA, a competent person is someone who can identify existing and predictable hazards and has authority to take corrective action.
If you've ever managed rental costs, you know this only works when there is a name on a piece of paper. Trust me on this one: 'we'll figure it out at the site' is the most expensive inspection plan. Write down the name, their trainer, and the date they were authorized.
2. Match the machine to the right inspection category
Not every lifting device is a crane, and not every piece of yellow iron belongs on the same checklist.
One search term that creates confusion is 'BOMAG excavators.' BOMAG doesn't manufacture excavators. The BOMAG lineup is compaction and asphalt equipment—soil compactors, roller compactors, asphalt pavers, cold planers. So if someone sends me a request for 'BOMAG excavator parts,' I stop and ask for the model plate. The brand name alone isn't enough to pick an inspection list.
A BOMAG roller compactor, for example, has its own daily walkaround checks: engine oil, coolant, hydraulic leaks, water separator, vibration on/off, brakes, ROPS, lights. It isn't a crane, so it shouldn't be on the crane inspection schedule. It should be on the equipment-specific schedule from its manual.
An engine hoist in a workshop is not a mobile crane. A bucket truck is not just a truck; the aerial platform has its own inspection rules under OSHA. The exact section depends on whether the site is general industry or construction. So before you ask 'who should inspect a crane?', ask 'which machine, and under which rule?'
3. Start with the manufacturer's manual, not a generic form
The manufacturer already wrote the inspection checklist. For a BOMAG roller compactor, the manual tells you exactly what to check before you start the engine. For a bucket truck, there are usually two manuals—one for the chassis and one for the aerial lift. For a crane, the load chart and operator's manual define the parts and intervals.
If your form doesn't match the manual, the form is wrong. I learned this after finding a generic lifting checklist used for an engine hoist in the shop. The form asked about boom angle and hoist rope. The engine hoist didn't have a boom angle gauge. The operator skipped half the form, and the item that actually mattered—a hydraulic cylinder leak—was not listed anywhere. What I mean is the manual is the baseline; a checklist that adds unrelated items creates blind spots, not safety.
4. Split the schedule: daily, frequent, and periodic
Who inspects a crane on Monday is not necessarily who inspects it in December.
- Daily pre-start: the operator or another competent person checks the critical items before the machine is used.
- Frequent inspections: a competent person at intervals based on service and environment—monthly is common.
- Periodic inspections: a qualified person, usually every one to twelve months, or after a major repair or assembly.
OSHA's crane rule in 29 CFR 1926 Subpart CC uses both roles: a competent person for frequent checks and a qualified person for periodic checks. A qualified person can be an external inspector, but only if you can document their training and experience. A bucket truck's aerial platform falls under aerial lift standards, not the crane standard, and an engine hoist follows the manufacturer's instructions plus your shop inspection program.
5. Make the record part of the invoice
The inspection record is not just a safety form—or rather, it is a safety form, but it is also a billing document. If you can't produce it, you pay twice: once for the inspection gap, and again for the delay while someone argues about it.
In 2023, I audited our equipment files and found seventeen paper logs, inconsistent names, and empty boxes. We moved to a QR-code inspection system in 2024. Each machine has a sticker; the operator scans it, completes the manual checklist, and adds a timestamped photo. It cut our reporting time from about twenty minutes per machine to five minutes and removed the 'left the binder in the truck' excuse. The whole system cost about the same as one hour of crane rental time.
At the same time, we kept paper backup for rental handoffs. Efficiency isn't about killing paper—it's about being able to find the record when the rental company asks for it.
Common Mistakes to Avoid
Mistake 1: Confusing insurance inspections with OSHA compliance
People think the insurance company will catch what they miss. Actually, an insurance inspection satisfies an insurance contract. Your duty to have a competent person doing pre-use checks is separate. The insurance report is not a substitute for the daily record.
Mistake 2: Applying one crane checklist to everything
A bucket truck, an engine hoist, and a BOMAG roller compactor have different rules and different risks. If you're not sure which standard applies, start with the manufacturer and the OSHA regulation for that equipment type.
Mistake 3: Letting the rental contract define your responsibility
A rental agreement might say the operator is responsible for daily inspection. But if your operator wasn't trained or designated, those words don't fix an inspection gap. Confirm the responsibility chain before the equipment arrives, not after the invoice.
So, who should inspect a crane? A named competent person using the right manual, at the right interval, with a record your finance team can find. Set that up before the equipment shows up, and you won't pay for an idle crane while two supervisors argue about a checklist.
