The ANSI B30 standards are a family of ASME-developed safety codes, accredited through the American National Standards Institute, that govern how lifting and material-handling equipment is designed, built, inspected, and operated in the United States. They cover overhead cranes, tower cranes, mobile cranes, slings, hooks, rigging hardware, and more than two dozen other categories of equipment. What makes them matter legally is that OSHA incorporates several volumes by reference, so their mandatory provisions carry the same force as any other federal workplace safety rule, and violations can reach $165,514 per instance.
How OSHA Turns B30 Into Federal Law
OSHA does not draft its own crane engineering specifications. It pulls in consensus standards from bodies like ASME and gives them regulatory weight. Under 29 CFR 1910.6 for general industry and 29 CFR 1926.6 for construction, standards incorporated by reference “have the same force and effect as other standards” in those parts.1Occupational Safety and Health Administration. 29 CFR 1910.6 – Incorporation by Reference2Occupational Safety and Health Administration. 29 CFR 1926.6 – Incorporation by Reference Only the mandatory provisions — language using “shall” — become enforceable. Advisory language does not carry the same bite, though it often reflects the standard of care that courts and insurers apply.
The clearest example is 29 CFR 1910.179, which governs overhead and gantry cranes in general industry and explicitly requires new overhead and gantry cranes to meet ANSI B30.2 design specifications.3eCFR. 29 CFR 1910.179 – Overhead and Gantry Cranes Construction work is governed by OSHA’s Subpart CC (29 CFR 1926.1400 and following), which sets its own inspection, certification, and operational rules and draws heavily on B30 concepts for inspection categories and personnel qualifications.
Which Volume Covers Your Equipment
The B30 series contains more than 25 volumes, each tied to a specific type of equipment or component. Every volume follows the same general structure — scope, definitions, construction and installation, inspection, testing, maintenance, and operation — but the specific requirements are tailored to the equipment. Identifying the right volume is the first step in figuring out what applies to your operation.
Overhead and Gantry Cranes (B30.2)
B30.2 covers overhead and gantry cranes with top-running bridges and single or multiple girder configurations, including cantilever gantry, semi-gantry, and wall cranes.4ASME. B30.2 – Overhead and Gantry Cranes These systems are usually fixed inside a building, running along elevated rails. The volume addresses construction, installation, operation, inspection, and maintenance of both hand-operated and power-driven models.
Tower Cranes (B30.3)
Tower cranes used in high-rise construction fall under B30.3, which covers fixed and traveling base cranes with luffing booms or horizontal jib trolleys, along with climbing arrangements.5ASME. B30.3 – Tower Cranes Mobile cranes fitted with tower attachments (B30.5) and self-erecting tower cranes (B30.29) are excluded.
Mobile and Locomotive Cranes (B30.5)
B30.5 covers crawler cranes, locomotive cranes, wheel-mounted cranes, and variations that share those fundamental characteristics.6American Society of Mechanical Engineers. ASME B30.5 – Mobile and Locomotive Cranes These machines move around a site while carrying loads, and their telescopic or lattice booms create stability challenges that require careful ground assessment and outrigger setup.
Slings (B30.9)
B30.9 addresses the fabrication, use, inspection, and maintenance of slings made from alloy steel chain, wire rope, metal mesh, synthetic fiber rope, synthetic webbing, and polyester fiber yarns in protective covers.7ASME. B30.9 – Slings The volume sets specific physical thresholds that force removal from service.
Below-the-Hook Lifting Devices (B30.20)
B30.20 covers structural and mechanical lifting devices, vacuum lifters, close-proximity and remotely operated lifting magnets, scrap and material-handling grapples, and clamps.8ANSI. ASME B30.20-2025 – Below-the-Hook Lifting Devices Many of these tools are custom-engineered, which makes the volume’s design-factor requirements especially important since generic safety data may not apply.
Rigging Hardware (B30.26)
B30.26 covers detachable rigging hardware: shackles, links, rings, swivels, turnbuckles, eyebolts, hoist rings, wire rope clips, wedge sockets, rigging blocks, and load indication devices.9ANSI Blog. ASME B30.26 – Rigging Hardware These are the small components people tend to overlook, but a failed shackle is as dangerous as a failed crane.
Other active volumes address jacks and hydraulic gantries (B30.1), portal and pedestal cranes (B30.4), derricks (B30.6), winches (B30.7), floating cranes and derricks (B30.8), hooks (B30.10), monorails and underhung cranes (B30.11), loads suspended from rotorcraft (B30.12), storage and retrieval machines (B30.13), side boom tractors (B30.14), overhead and stationary hoists (B30.16), cranes and monorails with underhung trolleys (B30.17), stacker cranes (B30.18), and cableways (B30.19).10The ANSI Blog.

Who Can Operate, Inspect, and Rig
The B30 standards and OSHA regulations define distinct personnel categories, and confusing them is one of the fastest ways to create a compliance gap.
A designated person — called an authorized person in OSHA’s construction rules — is someone the employer approves or assigns to perform a specific duty or occupy a specific location on the jobsite.11Occupational Safety and Health Administration. 29 CFR 1926.32 – Definitions The role is assignment-based, not credential-based.
A qualified person holds a recognized degree, certificate, or professional standing, or has demonstrated through extensive knowledge, training, and experience the ability to solve problems related to the work.11Occupational Safety and Health Administration. 29 CFR 1926.32 – Definitions Engineering evaluations, structural modifications, and load-rating changes usually require this level.
A competent person can identify existing and predictable hazards and is authorized to take prompt corrective action.11Occupational Safety and Health Administration. 29 CFR 1926.32 – Definitions OSHA’s construction crane rules require a competent person to conduct each-shift inspections.
For cranes used in construction, OSHA requires every operator to be certified or licensed before running covered equipment. Where a qualifying state or local government license exists, operators must hold it. Where none does, operators must be certified by an accredited crane operator testing organization — one accredited by a nationally recognized agency that evaluates written testing materials, practical exams, test administration, and grading. Certifications are valid for up to five years.12eCFR. 29 CFR 1926.1427 – Operator Qualification and Certification Signalpersons must demonstrate competence with standard hand and voice signals, and riggers must know how to select lifting gear based on load weight and balance. The employer is responsible for verifying all of it before anyone works on site.
Inspection Intervals
The standards use tiered inspection categories based on how often equipment runs and how severely it is used. The intervals and paperwork differ between general industry overhead cranes and construction cranes.
General Industry Overhead Cranes
Under 29 CFR 1910.179, all new and altered cranes must pass an initial inspection before first use. Frequent inspections run at daily to monthly intervals and focus on operating mechanisms, hydraulic and air lines, hooks, hoist chains, rope reeving, and worn components. Periodic inspections run at one- to twelve-month intervals depending on activity, service severity, and environment, and add a deeper structural and mechanical review.3eCFR. 29 CFR 1910.179 – Overhead and Gantry Cranes
Hook inspections show how the layers stack. A visual check happens every day the crane is used. A documented monthly inspection must include the date, the inspector’s signature, and the hook’s serial number or identifier. A hook that shows cracks, more than 15 percent increase in throat opening, or more than 10 degrees of twist takes the crane out of service.
Construction Cranes
Under 29 CFR 1926.1412, a competent person must visually inspect equipment before or during each shift it will be used. The same checklist applies to a monthly inspection, which must be documented with items checked, findings, inspector name and signature, and date, and retained for at least three months. At least every twelve months, equipment must undergo a thorough annual inspection, which goes beyond visual checks into structural and mechanical evaluation.13eCFR. 29 CFR 1926.1412 – Inspections
If any deficiency identified during a shift inspection is a safety hazard, the equipment must come out of service immediately until it is corrected. There is no grace period. Most enforcement actions start exactly here: someone spots a problem, decides to keep running, and OSHA arrives before the fix.
When Equipment Must Come Out of Service
One of the most consequential parts of B30 is the set of physical thresholds that force equipment off the job. Wire rope slings under B30.9 offer the clearest example. A sling must be removed if it shows any of the following:
- For wire strand or single-part slings, 10 randomly distributed broken wires in one rope lay, or 5 broken wires in one strand in one lay; for cable-laid slings, 20 broken wires per lay
- Kinking, crushing, birdcaging, or any other distortion of the rope structure
- Any evidence of exposure to excessive heat
- Cracked, deformed, or excessively worn end fittings that compromise sling strength
- Visible corrosion that affects load-bearing capacity
- Missing or illegible identification tags
These are bright-line rules, not judgment calls. When a rigger counts 10 broken wires in a single lay, the sling comes off the job. Similar physical thresholds appear in the volumes governing hooks, hardware, and other components.
Load Testing Before First Use
OSHA requires all new and altered overhead cranes to be load tested before initial use, covering hoisting, lowering, trolley travel, bridge travel, and all limit switches, locking devices, and safety devices. When a rated-load test is performed, the test load cannot exceed 125 percent of rated capacity unless the manufacturer recommends otherwise.14Occupational Safety and Health Administration. 29 CFR 1910.179 – Overhead and Gantry Cranes
Cranes that have been modified and rerated must also be load tested. A qualified engineer or the equipment manufacturer must verify the modification and supporting structure for the new rated load before the crane returns to service, and the new rated load must be displayed on the crane. Test reports must be kept on file and accessible to appointed personnel.
Records to Keep and For How Long
Written records are generally not required for frequent (daily-to-monthly) inspections under B30.2, with one important exception: monthly hook and hoist chain inspections require a dated, signed certification record even though they fall within the frequent category.3eCFR. 29 CFR 1910.179 – Overhead and Gantry Cranes
Periodic inspections require written, dated, and signed reports documenting the condition of cranes, hoists, chains, ropes, and other lifting devices.15ASME. ASME B30.2-2005 – Overhead and Gantry Cranes These records let the next inspector see whether a minor issue worsened or stabilized.
For construction cranes, the rules are more prescriptive. Monthly inspection documentation must include items checked, results, inspector name and signature, and date, and must be retained for at least three months.13eCFR. 29 CFR 1926.1412 – Inspections Annual comprehensive inspection records carry longer retention. Load test reports are kept for the life of the equipment. These records are the first thing an inspector asks for during an audit and the first thing a plaintiff’s attorney subpoenas after an accident.
What Noncompliance Costs
For 2026, OSHA’s maximum penalty for a serious violation is $16,550 per instance, which is also the daily maximum for failure to correct a previously cited violation. Willful or repeated violations carry a maximum of $165,514 per violation.16NAHB. Top OSHA Violations of 2025; No Increase in Penalties for 2026 A single crane with multiple unaddressed deficiencies can generate stacked citations that reach six figures quickly. A serious incident also triggers an investigation that can halt a jobsite for days or weeks, and willful violations can support criminal referrals when a fatality is involved.
