How Long to Keep Crane Inspection Records
Federal OSHA rules set short minimums for crane records: monthly inspections at least three months, annual inspections at least 12 months, and shift inspections not at all. Operator evaluations and signal person qualifications are kept while that person works for you. California stretches annual records to 48 months, and Washington requires written shift inspections kept three months. Most shops keep more than the minimum, because customers and insurers ask.
The retention table
| Record | Rule | Minimum retention | Who keeps it |
|---|---|---|---|
| Shift inspection | 1926.1412(d) | Not required to be documented federally | n/a |
| Monthly inspection | 1926.1412(e)(3) | 3 months | The employer that conducts the inspection |
| Idle 3+ months inspection | 1926.1412(h) | Same as monthly | Same |
| Annual / comprehensive | 1926.1412(f)(7) | 12 months | The employer that conducts the inspection |
| Wire rope monthly | 1926.1413(b)(4) | 3 months (documented as a monthly) | Same |
| Wire rope annual | 1926.1413(c)(4) | 12 months (documented as an annual) | Same |
| Operator evaluation | 1926.1427(f)(6) | While the operator is employed by you, available at the worksite | Employer |
| Operator certification | 1926.1427(d), (e) | Valid up to 5 years; keep a copy while valid | Operator and employer |
| Signal person qualification | 1926.1428(a)(3) | While the signal person is employed by you, available at the site | Employer |
| Audited employer program audits | 1926.1427(e)(5)(iv) | 3 years | The auditor |
| Derrick load test | 1926.1436 | Until re-tested or dismantled | Employer |
Every 1926.1412 and 1926.1413 document also has to be "available, during the applicable document retention period, to all persons who conduct inspections" under those sections (1926.1412(k), 1926.1413(e)). Your next inspector gets to see the last one.
Shift inspections: zero, unless your state or customer says otherwise
Subpart CC requires a shift inspection, but not a written one. OSHA's compliance directive says "Subpart CC does not require documentation of shift inspections." The federal floor is to do it and be able to describe how it was done.
That changes in some places:
- Washington: WAC 296-155-53405(4) says shift inspection records "must be kept" for at least three months, showing the items checked and results, and the name, signature and date. Electronic records are acceptable. The state's crane certifier also reviews the prior three months of shift inspections at certification time. See Washington's crane rules.
- GCs: many want today's sheet in the cab, and some want daily checklists turned in. Power Construction in Chicago, for example, wants its mobile crane checklist submitted daily.
Monthly: three months, but plan on more
Three months is the federal floor. It also lines up with what GCs usually ask for: the last three monthly reports. If you only keep three, you will be fine on paper and stuck the day someone asks about a defect that started four months ago. See monthly crane inspection documentation.
Annual: 12 months federally, 48 months in California
Federally, keep the annual at least 12 months. California's Title 8 §5031 says annual records "shall be maintained on file for a minimum of 48 months by the employer," and the most recent quarterly periodic inspection record must also be kept on file. California also wants a copy of the certificate with the crane or at the project site (§5025). See California crane certification and annual crane inspection requirements.
People records follow the person
The operator evaluation (1926.1427(f)(6)) and the signal person qualification (1926.1428(a)(3)) both use the same idea: available at the worksite or site while the person is employed by you. There is no month count. In practice:
- Keep the evaluation for as long as the operator works for you, and keep a copy after they leave in case questions come up about past work.
- Re-evaluate after retraining. 1926.1427(f)(7) requires it, and the new document goes in the file next to the old one.
- Keep the certification card copy with its expiry date.
Who keeps the record on a rental
The inspection rules tie records to "the employer that conducts the inspection." On an operated rental your operator usually does the shift and monthly, so you keep them. On a bare rental the contract often puts inspections and the crane log on the renter, and the log comes back with the crane. Read your rental agreement and make sure the log actually comes home. More in bare rental vs operated rental paperwork.
Why most shops keep more than the minimum
The regulations are the floor. Other people ask for history:
- Insurers. The Skyward crane and rigging supplemental application asks for crane inspection reports, operator certificates, and whether you use a written form for crane inspections and document all maintenance.
- GCs and owners. They ask for the current annual and recent monthlies on every job.
- Buyers. When you sell a crane, inspection history affects the price.
- Claims and lawsuits. Records help show what was done, and when. How long to keep them for that purpose is a question for your insurer and your attorney, not a regulation.
A practical policy many owners land on: keep every annual for the life of the crane, keep monthlies and shift sheets at least until the next annual is done, and keep people files for the length of employment plus some years after.
A filing setup that works for a small shop
You do not need anything fancy. You need one place per crane and one place per person, and the discipline to put things there the same day.
Per crane:
- Current annual certificate and full report, plus every earlier annual
- Monthlies, newest first, at least back to the last annual
- Shift sheets, if your state or customers want them
- Repair, modification and post-assembly records since the last annual
- Load chart and range chart for that serial number
- State certificates, such as a Washington certificate of operation
Per person:
- Certification card, both sides, with the expiry date
- The 1427(f) evaluation and any re-evaluations
- Rigger or signal person qualification, with signaling types listed
- Medical card, if customers ask for one
One list for expiry dates. Annual due dates, card expiries, medical cards, your COI. Look at it every week. Most retention trouble is not throwing things away too early. It is not being able to find the right page when a GC asks, or finding out at the gate that something lapsed.
Paper or electronic
Federal Subpart CC does not say records must be on paper. Washington's shift rule says outright that "electronic records are acceptable," and OSHA's directive tells compliance officers that acceptable signal person documents "include both physical and electronic records." Whatever you use, the record needs the required fields, including a signature, and you need to be able to produce it at the site.
Where CraneFile fits
We're building CraneFile with a handful of crane shops. Every inspection and every card goes into the crane's or the person's file and stays there, searchable by crane and date, with nothing tossed at three months. It is not live yet. If you want in early, reserve a spot or call us at (786) 471-4419.
This is plain-English guidance, not legal advice. The regulation text governs. For retention beyond the legal minimums, ask your insurer and attorney.
Questions we get
How long does OSHA require crane inspection records to be kept?
Under 29 CFR 1926.1412, monthly inspection records are kept at least three months and annual/comprehensive inspection records at least 12 months. Shift inspections do not have to be documented under federal Subpart CC.
How long do I keep a crane operator's evaluation?
The 1926.1427(f) evaluation document must be available at the worksite while the operator is employed by you. There is no fixed number of months; it follows the employment.
Does California require longer retention for crane records?
Yes. Title 8 §5031 requires annual inspection records to be kept on file at least 48 months by the employer, and the most recent periodic (quarterly) inspection record kept on file.
Should I keep crane records longer than the minimum?
Many shops do. GCs ask for recent monthlies and the current annual, insurers ask for inspection reports at renewal, and buyers ask for history when you sell a crane. The minimums are a floor. Ask your insurer and attorney what they want you to keep.
