Introduction

An overhead crane inspection program is not optional. OSHA 29 CFR 1910.179 requires documented inspections for every overhead crane in general industry. ASME B30.2 defines the technical standard for what those inspections must cover. Both regulations have legal force. Both are cited in OSHA enforcement actions.

But beyond compliance, the inspection program is what stands between you and an unplanned failure during production. The most common causes of overhead crane incidents — wire rope deterioration, brake degradation, limit switch failure, and hook deformation — are all detectable during routine inspection. They are not detectable without one.

This guide provides the complete three-tier inspection framework. It covers every item required by OSHA 1910.179 and ASME B30.2 at each inspection tier. It identifies who must perform each tier. It explains the documentation and retention requirements. And it gives you the rejection criteria for the most common inspection findings.

Part 1: Understanding the Three Inspection Tiers

OSHA 1910.179 and ASME B30.2 establish three distinct inspection tiers. Each has a different scope, a different required performer, and different documentation requirements.

Tier 1: Pre-Shift (Frequent) Inspection

Frequency: before each shift, or daily at minimum.
Required performer: a competent person. In practice: the crane operator, if trained and designated by the employer.
Documentation: OSHA does not require written records for daily inspections — but most employers require a signed checklist. Written documentation is strongly recommended for liability and incident investigation purposes.

The pre-shift inspection is the operator’s confirmation that the crane is safe to operate that shift. It covers the observable condition of all safety-critical components. It does not involve disassembly, measurement, or technical analysis.

Tier 2: Monthly (Frequent — Extended) Inspection

Frequency: monthly minimum. More frequent for high-duty or harsh-environment cranes.
Required performer: a competent person — typically a qualified maintenance technician rather than the operator.
Documentation: written record required and retained for minimum 12 months.

The monthly inspection extends the pre-shift scope to include components that require closer access, functional testing under load, and comparison to previous inspection records. It identifies degradation trends that a daily visual inspection cannot detect.

Tier 3: Annual (Periodic) Inspection

Frequency: minimum annually. More frequent for cranes in severe service (CMAA Class D and above) or following any significant repair.
Required performer: a qualified person — a person who has thorough knowledge of crane design, construction, maintenance, and inspection through training or experience, or both.
Documentation: written record required and retained for the life of the crane. This record is the crane’s permanent structural history.

The annual inspection covers the complete crane — structural, mechanical, and electrical. It includes load testing when required, NDT examination of structural welds when indicated, and formal assessment of remaining service life.

Part 2: Pre-Shift Inspection Checklist

Complete these items before the first lift of every shift. The inspection should take 10 to 15 minutes for a standard bridge crane.

Controls and Safety Devices

☐ All pendant or cab controls operate correctly and return to neutral position when released.
☐ Emergency stop button de-energizes all crane motions immediately when pressed.
☐ Emergency stop resets correctly when released — crane does not restart automatically.
☐ Upper limit switch: raise the empty hook slowly to the limit. The hoist must cut power before the hook block contacts the hoist body.
☐ Lower limit switch (if fitted): lower the empty hook to the limit. The hoist must cut power before the chain or rope runs out.
☐ All directional labels on pendant buttons correspond to actual crane motion direction.
☐ Festoon cable or radio transmitter operates without interruption throughout the full travel range.

Hook and Below-Hook Hardware

☐ Hook safety latch: press the latch open and release. It must spring back fully closed without sticking.
☐ Hook throat opening: no visible spreading beyond the original profile. (Rejection criterion: throat opening increased 15% above nominal — ASME B30.2.)
☐ Hook body: no visible cracks, gouges, or deformation. No twisting of the shank.
☐ Hook swivels freely without binding.
☐ All rigging hardware (slings, shackles, below-hook devices): visual check for damage. Remove from service any item with visible cracking, deformation, or missing identification marking.

Wire Rope or Load Chain

☐ Wire rope: inspect the visible rope length from the drum to the hook block. Look for: broken wires protruding from the surface, kinking or birdcaging, diameter reduction visible to the eye, corrosion or dark discoloration indicating internal deterioration. (Rejection criteria per ASME B30.2: 2 broken wires in any 6-rope-diameter length; 6 broken wires in any 30-rope-diameter length; visible diameter reduction to 67% of nominal.)
☐ Load chain: inspect the full visible chain for: bent or deformed links, visible cracks, excessive elongation, corrosion pitting. (Rejection criteria: any visible crack; link bar diameter worn to 90% of nominal; 11-link elongation exceeds 2%.)
☐ Rope drum: first and last wraps of rope remain on drum at hook’s lowest position (minimum 2 wraps required — ASME B30.2).

Hoist Brake

☐ Raise the empty hook approximately 300mm above the floor.
☐ Release the “up” control.
☐ Observe for 30 seconds.
☐ Zero downward drift is required. Any movement is a rejection condition — tag out immediately.

Structural and Mechanical Visual Check

☐ Bridge girder: no visible deflection, cracking, or unusual deformation.
☐ End trucks and trolley: no loose bolts, unusual wear, or damage visible from the floor.
☐ Runway rails: no visible rail displacement, broken clips, or unusual gap at rail joints.
☐ Crane travel path: clear of obstacles, personnel, and unauthorized equipment.

Part 3: Monthly Inspection Checklist

The monthly inspection covers all pre-shift items plus the following. Perform with the crane isolated per LOTO procedures where component access requires it.

Hoist Mechanism

☐ Wire rope: complete inspection of full rope length. Pay out the full rope to inspect the portions normally stored on the drum. Check rope end termination at drum anchor — no cracked ferrules, no strand slippage in socket terminations.
☐ Rope drum: inspect drum groove profiles for uneven wear. Check drum flanges for cracking.
☐ Load chain: complete length inspection including stored chain in the chain container.
☐ Sheaves: inspect groove profiles for wear matching rope diameter. Sidewall wear indicates rope tracking problems. Check sheave bearings for rough rotation.
☐ Hoist gearbox: check oil level through sight glass. Look for oil leakage at seals. Listen for unusual gear mesh noise during hoist operation.
☐ Hoist motor: check motor mounting bolts for tightness. Verify cooling fan rotates freely. Inspect motor terminal box — no moisture entry, all connections tight.
☐ Hoist brake: measure lining thickness and compare to manufacturer’s minimum specification. Clean brake disc contact surface — no oil or grease contamination. Verify air gap between disc and armature plate is within specification.

Travel Drives and Rails

☐ Bridge and trolley drive motors: same checks as hoist motor.
☐ Travel wheel flanges: inspect for wear patterns. Uniform flange contact across all four bridge wheels indicates correct rail alignment. Concentrated flange contact on one side indicates misalignment.
☐ Travel wheel treads: check for flat spots (feel as periodic thumping during travel), flange cracks, and tread diameter differences between wheels on the same end truck.
☐ Runway rails: inspect full rail length accessible from the bridge. Check for: loose clip bolts, rail joint gaps outside specification (standard: 6mm maximum for indoor cranes), rail joint step (maximum 0.5mm), and rail surface wear or scoring.
☐ End stops and bumpers: inspect for damage from previous contact. Check mounting bolts.

Electrical Systems

☐ Conductor bar or festoon cable: inspect full length for damaged insulation, loose connections, and current collector wear.
☐ Control pendant: inspect for physical damage, check cable strain relief.
☐ All limit switches: verify mounting security and actuator condition. Test each limit switch function.
☐ Contactor panel or VFD: inspect for overheating signs (discolouration, burning odour). Check all connections for tightness.
☐ Ground continuity: verify that measuring from hook to facility ground gives less than 1 ohm resistance.

Documentation

Record these items on the monthly inspection form:

Date of inspection
Inspector name and qualification
Crane identification (asset number)
Each checklist item: pass, fail, or N/A
Description of any deficiency found
Action taken: repaired before return to service, or tagged out pending repair
Inspector signature

Retain monthly inspection records for minimum 12 months. Many facilities retain for 3 years as a best practice.

Part 4: Annual Inspection Checklist

The annual inspection is the most comprehensive tier. It requires a qualified person — not simply a competent person. Plan for a 4 to 8 hour crane outage for a standard 5 to 20-tonne bridge crane.

Complete Structural Inspection

☐ Main girder: full visual inspection of the bottom flange, webs, and top flange. Use a flashlight and mirror to inspect the underside of the bottom flange. Look specifically for: transverse cracks at weld toes of stiffener attachments, horizontal cracks in the web above the bottom flange weld, and any previously marked locations from prior inspections.
☐ End trucks: full inspection of all welded connections. Include the girder-to-end-truck connection, wheel axle mounts, and bumper attachment points.
☐ If any visual indication of cracking is found: commission NDT (magnetic particle or dye penetrant testing) before returning the crane to service.
☐ All structural bolts: verify torque at a statistically representative sample (minimum 20% of all structural connection bolts).

Complete Mechanical Inspection

All monthly inspection items, plus:

☐ Complete hoist disassembly-level inspection (or inspection per manufacturer’s annual service procedure).
☐ Bearing condition: where accessible without full disassembly, check bearing preload, smoothness, and any audible roughness.
☐ Gear tooth condition: where accessible through inspection covers, inspect gear tooth profiles for pitting, scoring, and fractures.
☐ Rope replacement evaluation: assess whether rope condition warrants replacement regardless of rejection criteria — rope approaching 3 to 5 years of age in CMAA Class D service should be considered for replacement as preventive maintenance even if current rejection criteria are not yet met.

Load Testing Requirements

ASME B30.2 requires a load test when any of the following apply:

The crane has been altered since its last load test. New hoist installation, structural modification, or runway modification all require a new load test.
The crane has been reinstalled at a new location.
A periodic inspection reveals a condition requiring the inspector to confirm structural adequacy.

Load test procedure per ASME B30.2: lift 125% of rated load. Travel the load through the full coverage area. No structural deformation or permanent deflection. All safety devices must function correctly during the test. Document the test with date, load, test scope, and results.

Documentation Package

The annual inspection report must contain:

Complete checklist with pass/fail for every item
Description of every deficiency and the corrective action taken
NDT reports if NDT was commissioned
Load test report if load test was performed
Inspector’s name, qualifications, and signature
Statement of fitness for continued service or list of conditions for continued service

Retain annual inspection reports for the life of the crane. These records are legal documents. They are required by OSHA for incident investigation. They are required by insurance carriers for liability coverage.

Part 5: Rejection Criteria Quick Reference

This table summarizes the key rejection criteria from ASME B30.2 and OSHA 1910.179.

Frequently Asked Questions

Q: Who qualifies as a “qualified person” for the annual overhead crane inspection?
A: ASME B30.2 defines a qualified person as one who has thorough knowledge of crane design, construction, maintenance, and inspection by training, experience, or both. In practice: a licensed professional engineer with crane inspection experience, a manufacturer-certified crane inspector, or a person with documented formal training in crane inspection (such as ASME certification or equivalent). The qualification must be documented. A general maintenance technician without specific crane inspection training does not meet the qualified person standard for annual periodic inspections.

Q: If we discover a deficiency during the pre-shift inspection, can we operate the crane in a limited way while waiting for repair parts?
A: It depends on the nature of the deficiency. A non-critical deficiency — such as a minor oil seal weep or a rail clip that needs retorquing — may allow continued operation at the inspector’s discretion with the deficiency documented and a repair scheduled. A safety-critical deficiency — any brake drift, any limit switch failure, any hook latch failure, any wire rope at rejection criteria — requires immediate tagging out. OSHA 1910.179(f)(1) requires that defects affecting safe operation be repaired before the crane is placed in service. There is no provision for operating with known safety-critical deficiencies.

Q: Does a crane that was not used during a month still require a monthly inspection?
A: ASME B30.2 specifies monthly inspection for cranes in “regular service.” A crane that has been completely idle for a month — not operated at all — is not in regular service during that period. However, before returning any crane to service after an extended idle period (typically defined as 30 days or more without operation), a complete pre-service inspection equivalent to the monthly inspection scope is required. The extended idle period can allow corrosion, seal deterioration, and lubricant separation that would not occur during regular service.
