OSHA 1910.179 monthly crane inspection: the exact checklist and what inspectors flag
OSHA 29 CFR 1910.179 requires monthly inspection of overhead and gantry cranes in US general industry. Here is the exact checklist, common findings from OSHA inspection reports, and the record-keeping OSHA cares about most.
By Hovermarks team
Quick answer. OSHA 29 CFR 1910.179 requires overhead and gantry crane inspection at three tiers: daily/before-shift (visual by the operator), frequent (monthly by a competent person), and periodic (1 to 12 months depending on service, by a qualified inspector). The monthly frequent inspection covers 13 specific items listed at 1910.179(j)(2). Records must be kept on file with a signed report from the inspector, retained for the working life of the crane. The most common finding on OSHA inspections is not the absence of an inspection but the absence of a record proving one happened.
Every US employer running an overhead or gantry crane in general industry falls under 29 CFR 1910.179. Construction cranes are covered separately by 29 CFR 1926 Subpart CC and 1926.1400 onward. This post covers the general-industry monthly inspection specifically.
Who has to inspect
OSHA distinguishes three inspection roles:
- Operator performs the pre-shift visual (before each shift the crane is used).
- Competent person performs the frequent (daily to monthly) inspection.
- Qualified inspector performs the periodic (1 to 12 months) inspection.
Competent person is someone the employer designates as having relevant training and experience. Qualified inspector under 1910.179 is someone who has been formally qualified for the specific inspection scope.
Frequency selection
1910.179(j)(1)(ii) sets the frequent inspection interval based on service type:
- Normal service: monthly.
- Heavy service: weekly to monthly, based on manufacturer or qualified person's determination.
- Severe service: daily to weekly.
Most general-industry overhead cranes are normal service, so monthly is the default. Service classification depends on load spectrum, duty cycle, and environment.
The exact monthly checklist (1910.179(j)(2))
Six categories with 13 specific items:
Category 1: Operating mechanisms
- Operating mechanisms for maladjustment interfering with proper operation.
- Deterioration or leakage in lines, tanks, valves, drain pumps, and other parts of air or hydraulic systems.
Category 2: Hooks
- Hooks with deformation or cracks. Visual inspection daily; monthly inspection with a magnaflux type check advised.
Category 3: Hoist chains
- Hoist chains, including end connections, for excessive wear, twist, distorted links interfering with proper function, or stretch beyond manufacturer's recommendations. Visual inspection monthly.
Category 4: Rope
- Running ropes visual inspection at least monthly. Written report of any deterioration by a qualified person, with dated signature.
Category 5: All functional operating mechanisms
- Excessive wear of components.
- Rope reeving for compliance with the manufacturer's recommendations.
- Any conditions affecting the safety of the crane.
Category 6 (electrical and control)
- Deterioration or leakage in air or hydraulic system components.
- Excessive wear of brake system parts, linings, pawls, and ratchets.
- Load, wind, and other indicators over their full range for any significant inaccuracies.
- Gasoline, diesel, electric, or other power plants for improper performance or noncompliance with applicable safety requirements.
- Excessive wear of chain drive sprockets and excessive chain stretch.
Record requirements
1910.179(j)(2)(iv) requires:
- Certification records that include the date of inspection.
- The signature of the person who performed the inspection.
- The serial number or other identifier of the crane inspected.
Records are kept on file where available to appointed personnel. Retention is not specified in years; general OSHA practice is retain for the life of the equipment plus a period after retirement.
What OSHA inspectors flag most
From published OSHA inspection reports and citation data across recent years:
- Missing records for months when inspections were verbally reported as done. Verbal "we did it" is not compliant. The record with dated signature is the compliance evidence.
- Same signature on every monthly report for 12 months. No evidence the inspector actually attended; looks like backfilled paperwork.
- Wire rope reports missing the qualified-person written statement. The visual check by the operator is not sufficient; running ropes need a qualified person's dated signed report.
- Hook wear measured by eye rather than with a caliper. Hook throat wear must be measured against manufacturer specification.
- Load test records missing for cranes that were altered, repaired, or modified in the past year.
Beyond the frequent inspection, the annual periodic inspection under 1910.179(j)(3) has its own more detailed scope. Missing periodic inspection records is a more serious finding than missing frequent-inspection records.
What a compliance tool should support
- Per-crane record. Serial number, service classification, custom checklist that reflects the crane's specifics (top-running vs under-running, single vs double girder, main hoist and auxiliary hoist).
- Signature on device. The competent person's signature captured on the tablet or phone, not on paper that then goes into a file.
- Manufacturer-spec reference. Hook wear thresholds, chain stretch limits, rope replacement criteria loaded per crane so the inspector does not have to reference a manual mid-inspection.
- Non-conformance escalation. Any finding categorised as immediate risk triggers an out-of-service tag and notifies the responsible manager.
- Auditor read-only login. OSHA compliance officer or insurance surveyor sees the complete inspection history without waiting for HR to email it.
