Technical GuideCrane Periodic Inspection
Periodic inspection for cranes: typical inspection interval, test load, who can carry it out, and how to prepare — a general guide, not a substitute for your local regulation.
The general framework
Most countries require lifting and conveying equipment to be periodically inspected by authorised or competent personnel under workplace-safety regulation; the details and terminology differ by jurisdiction, so this guide describes the common pattern rather than any one country's specific rule — check the regulation that applies where your crane operates.
A commonly seen rule is that the inspection interval should not exceed one year unless a standard specifies otherwise, and that lifting equipment should be able to safely lift and hold at least 1.25 times its rated load during a test. Treat these as typical figures to confirm locally, not universal constants.
Keeping the report on file matters as much as carrying out the inspection. After a workplace incident or during an audit, this is usually the first document requested.
What happens during the inspection
A periodic inspection typically has two parts: examination and testing.
The examination covers the load-bearing structure (girder, end carriages, connections), the hoist mechanism, rope/chain, hook, sheaves and drum, brakes, limit switches, the overload limiter, the electrical panel, controls and the runway — checked visually and with measurement.
In the test, a load is applied to the crane to verify brake holding, the overload limiter's trip point, and general behaviour. After the test, the structure is re-examined for permanent deformation.
| Topic | Typical rule (verify locally) |
|---|---|
| Basis | Workplace-safety / lifting-equipment regulation in the country of use |
| Inspection interval | Commonly up to 1 year unless a standard says otherwise |
| Test load | Commonly at least 1.25× the rated load |
| Who inspects | Authorised personnel / accredited inspection bodies |
| Responsibility | Typically the employer |
| Records | Report kept on file, findings closed out |
This table is general background only; for the actual scope of your obligation, check the current regulation in your country and follow the guidance of the body carrying out the inspection.
How to prepare for the inspection
- Gather the documentsNameplate data, manufacturing/compliance documents, the previous inspection report and maintenance records.
- Open up access to the craneClear the area under the crane on inspection day and provide access to the maintenance platform and access points.
- Check the safety elementsTest that the limit switches, e-stop and overload limiter work beforehand; re-enable anything that's been disabled.
- Review the rope and brakeAddress a rope near its discard criterion or a poorly adjusted brake before the inspection.
- Prepare the test loadHave a known-weight test load matching 1.25× the rated load ready, with a suitable sling.
- Have an operator presentA competent operator to run the crane should be available throughout the inspection.
The most common findings
The findings seen most often on site cluster around the same headings every time: a disabled or mis-set overload limiter, a non-functioning limit switch, a poorly adjusted brake, rope past its discard criterion, a missing or unreadable nameplate/capacity marking, a misaligned runway, and a previous inspection report that can't be located.
Most of these are items that a half-day of preparation before the inspection date can clear up.
Technical terms
| Term | What it means |
|---|---|
| Periodic inspection | The examination and testing of work equipment by authorised personnel at set intervals. |
| Test load | The load applied to the crane during inspection, a set multiple of the rated load. |
| Rated load | The nominal lifting capacity stated on the crane's nameplate. |
| Non-conformity | A shortfall identified during inspection that needs to be corrected. |
Frequently asked questions
Is the interval always one year, everywhere?
In many jurisdictions, unless a standard specifies otherwise, the rule is that the interval should not exceed one year — but this varies by country and by how demanding the duty is. Check your local regulation for the exact figure.
Who is allowed to carry out the inspection?
Regulations typically require an "authorised" or "competent" person or body; in practice this means someone or some organisation with the relevant accreditation. Confirming the scope of that accreditation before booking the inspection is worth doing.
If the report finds a non-conformity, does the crane stop working?
Depends on how serious the finding is. Anything that directly affects safety usually means the equipment stays out of service until it's fixed; lesser findings are often given a deadline. Either way, fixing it is the employer's responsibility.
