Rigging Inspection & Documentation — ASME B30 Compliance
Three inspection levels — know the difference
1. Pre-Use (before each shift)
Visual check by the rigger: cracks, cuts, distortion, wear, missing markings. Document only if a problem is found; otherwise move into service.
2. Frequent (monthly to quarterly)
Documented inspection by a trained inspector. Checks dimensions (throat opening, link diameter, bow wear), fastener integrity, latch function. Log findings in a written record retained for 3 years minimum.
3. Periodic (annual)
Documented inspection by a certified third-party or in-house certified inspector. Includes load tests where applicable, non-destructive testing (dye penetrant, magnetic particle, ultrasonic), and final certification. Records retained for 3 years minimum, often longer per customer requirements.

- Equipment ID / serial number / traceability code
- Date of inspection
- Inspector name, signature, qualification level
- Results: PASS / CONDITIONAL PASS (specify) / FAIL
- Specific measurements (throat opening, link diameter, etc.)
- Next inspection due date
- Photographs of any anomalies

Why documentation matters
OSHA, ASME, and insurance require documented inspection of all overhead lifting equipment. Failing to document an inspection that caught a problem is legally no better than not having done the inspection. If an accident occurs, insurance and OSHA will ask for your inspection log. If you can't produce one, the case turns against you fast.
