OSHA pre-lift plan requirements for cranes come from 29 CFR 1926 Subpart CC, and the clearest written-plan mandate sits in Section 1926.1432: any lift where more than one crane or derrick supports the load must be planned in advance by a qualified person. A second mandatory planning duty applies to personnel hoisting under 1926.1431. Outside those two triggers, industry practice treats any lift above 75 percent of a crane’s rated capacity as a “critical lift” that deserves the same written treatment, because 1926.1417 forces the operator to stop and verify the load weight at that threshold anyway.
When a Written Plan Is Required
Section 1926.1432(a) is the unambiguous one. Before a multi-crane or multi-derrick lift begins, the operation “must be planned,” and a qualified person has to develop that plan.1eCFR. 29 CFR 1926.1432 Multiple-Crane/Derrick Lifts Supplemental Requirements
Personnel hoisting is the second trigger. When workers ride a crane-suspended platform, 29 CFR 1926.1431 requires a documented trial lift at every placement location, a competent-person inspection of the platform and rigging after the trial, and a showing that conventional access (ladders, scaffolds, aerial lifts) would be more hazardous or infeasible.2Occupational Safety and Health Administration. 29 CFR 1926.1431 – Hoisting Personnel The regulation does not use the phrase “pre-lift plan,” but the paperwork it demands amounts to one.
A third rule pushes most contractors toward a written plan even when neither trigger applies. Under 1926.1417(o)(3)(ii), once a load-indicating device shows the load exceeds 75 percent of the crane’s maximum rated capacity at the longest radius to be used, the operator must stop and independently verify the load weight before continuing.3Occupational Safety and Health Administration. 29 CFR 1926.1417 – Operation Combined with the general obligation to follow manufacturer procedures, that verification duty is why most crane contractors handle any lift above 75 percent of rated capacity with the same rigor as a multi-crane pick, even though Subpart CC does not explicitly command it.
Who Writes the Plan and Who Runs the Lift
The qualified person who writes a multi-crane lift plan is defined in 29 CFR 1926.32 as someone who has demonstrated the ability to solve problems related to the work through a recognized degree, professional standing, or extensive knowledge and experience.4Occupational Safety and Health Administration. 29 CFR 1926.32 – Definitions The role is not automatically the most senior rigger on site. It requires enough technical depth to calculate load distribution between cranes, evaluate rigging geometry, and identify failure points ahead of time.
When the qualified person determines the lift’s complexity requires specialized knowledge, the employer must bring in engineering expertise.1eCFR. 29 CFR 1926.1432 Multiple-Crane/Derrick Lifts Supplemental Requirements In practice, that usually means a registered professional engineer stamps the plan. Fees range from a few hundred dollars for a straightforward two-crane pick to several thousand for a complex sequence.
On the day of the operation, a “lift director” takes charge. The regulation defines the lift director as someone who meets the criteria for both a competent person and a qualified person, or a competent person assisted by one or more qualified individuals.1eCFR. 29 CFR 1926.1432 Multiple-Crane/Derrick Lifts Supplemental Requirements The lift director is the single point of authority during the lift, and everyone on the crew takes direction from that person. The lift director can stop the operation at any point.
What the Plan Has to Cover
Section 1926.1432(a)(2) says the plan must be “designed to ensure that the requirements of this subpart are met.” That broad language forces the plan to address every Subpart CC requirement relevant to the specific lift, not a generic checklist.
Load Weight and Crane Configuration
Load weight is the foundation everything else rests on. Under 1926.1417(o)(3)(i), the weight has to come from a recognized source such as the manufacturer, or from a calculation method the industry accepts (for example, computing a steel beam’s weight from measured dimensions and known per-foot density).3Occupational Safety and Health Administration. 29 CFR 1926.1417 – Operation The plan records that weight and adds the weight of every hook, spreader bar, sling, and other lifting accessory. A few hundred pounds of unaccounted rigging can push a crane past its rated capacity at a given radius.
The plan then specifies each crane’s configuration: boom length, jib length and offset angle, counterweight setup, and working radius at every phase of the lift. Those numbers get checked against the manufacturer’s rated capacity chart, which along with all operational procedures must be readily available in the cab at all times.3Occupational Safety and Health Administration. 29 CFR 1926.1417 – Operation For multi-crane lifts, the load distribution between cranes needs to be calculated at each phase so no crane exceeds capacity at any point during the sequence.
Ground Conditions and Underground Hazards
Rated capacity means nothing on ground that cannot support the machine. Section 1926.1402(b) prohibits assembling or using a crane unless ground conditions are firm, drained, and graded well enough to meet the manufacturer’s specifications for support and level.5Occupational Safety and Health Administration. 29 CFR 1926.1402 – Ground Conditions The plan should document required surface preparation and the mats, cribbing, or other supporting materials that will spread outrigger or track bearing pressure.
Underground hazards need explicit attention. The controlling entity for the project must inform the crane user and operator about known hazards beneath the setup area, including voids, underground tanks, and buried utilities, if those hazards appear in site drawings, as-built drawings, soil analyses, or are otherwise known.5Occupational Safety and Health Administration. 29 CFR 1926.1402 – Ground Conditions An outrigger over an unidentified sewer vault can punch through when the load comes on.
Power Line Clearances
Section 1926.1408 requires the employer to determine whether any part of the equipment, load line, or load (including rigging) could get within 20 feet of a power line when operating at maximum working radius in the work zone.6Occupational Safety and Health Administration. 29 CFR 1926.1408 – Power Line Safety (Up to 350 kV) Equipment Operations If it could, the employer picks one of three compliance options: de-energize and ground the line, keep a 20-foot clearance using barricades and a dedicated spotter, or determine the line’s voltage and hold the minimum approach distance in Table A of that section.
The plan documents which option applies, the voltage of nearby lines, the clearance distance, and the physical controls (warning lines, barricades, elevated markers) that will keep crane and load outside that distance. Even traveling without a load, minimum clearance distances apply under 1926.1411, ranging from 4 feet for lines under 750 volts up to 20 feet for lines between 750 kV and 1,000 kV.7Occupational Safety and Health Administration. 29 CFR 1926.1411 – Power Line Safety While Traveling Under or Near Power Lines With No Load
Rigging
The plan specifies the type, size, and rated capacity of every piece of rigging hardware. All rigging equipment must carry permanent markings showing the manufacturer’s recommended safe working load, and no piece can be loaded beyond that rating.8Occupational Safety and Health Administration. 29 CFR 1926.251 – Rigging Equipment for Material Handling Custom lifting accessories such as modular panel grabs or specialized clamps must be proof-tested to 125 percent of their rated load before use.
Rigging selection accounts for the load’s shape, center of gravity, and any tendency to shift during the pick. Sling angles, hitch types, and connection points all affect the actual forces on each piece of hardware, and the plan spells out those details so the rigging crew can verify the correct equipment is on site and serviceable before the lift.
Communication and Signals
Signals to the operator must be by hand, voice, audible device, or a new signaling method agreed on before the operation.9Occupational Safety and Health Administration. 29 CFR 1926.1419 – Signals General Requirements The plan names the signal person, states which signaling method will be used, and confirms that method fits the site (line of sight, radio range, noise). When non-standard hand signals are used, the signal person, operator, and lift director must agree on those signals before work begins.
Signal persons must be qualified. The employer must maintain documentation showing each type of signaling for which the person meets the qualification requirements, and that documentation has to be available at the site.10Occupational Safety and Health Administration. 29 CFR 1926.1428 – Signal Person Qualifications
Personnel and Operator Certification
The plan identifies every person involved and their role: operator, rigger, signal person, lift director. Operators must be trained, certified or licensed, and evaluated before operating any equipment covered by Subpart CC.11Occupational Safety and Health Administration. 29 CFR 1926.1427 – Operator Training, Certification, and Evaluation Where a state or local government issues crane operator licenses, operators must hold the license for the jurisdiction. Exceptions exist for derricks, sideboom cranes, and equipment rated at 2,000 pounds or less.
Operators-in-training face restrictions that matter for planning. A trainee who is not yet certified cannot operate within 20 feet of a power line up to 350 kV (or within 50 feet above 350 kV), cannot hoist personnel, and cannot participate in multi-crane lifts.11Occupational Safety and Health Administration. 29 CFR 1926.1427 – Operator Training, Certification, and Evaluation
Personnel Hoisting Adds a Trial Lift
Hoisting workers on a suspended platform pulls in a separate set of procedures under 1926.1431. The employer must first show that conventional access methods would be more hazardous or are not feasible given the project’s structural design or site conditions.2Occupational Safety and Health Administration. 29 CFR 1926.1431 – Hoisting Personnel
Before anyone rides, the employer conducts a trial lift. The unoccupied platform, loaded to at least the anticipated lift weight, has to travel from the boarding point to every location where workers will be positioned. A competent person then inspects the equipment, rigging, and platform immediately after the trial for defects or adverse effects. The trial must be repeated whenever the crane is relocated, the lift path changes, the crane is reconfigured, the operator changes, or the lift crew changes. Just prior to hoisting personnel, the platform gets hoisted a few inches for a final level, stability, and seating check.
The pre-lift plan for personnel hoisting therefore documents the trial lift procedure, the inspection protocol, the competent person responsible, and the criteria for repeating the trial.
The Pre-Lift Meeting and On-Site Documents
For multi-crane lifts, the lift director must review the plan in a meeting with everyone involved in the operation.1eCFR. 29 CFR 1926.1432 Multiple-Crane/Derrick Lifts Supplemental Requirements The meeting confirms that each crew member understands the specific assignment, the communication method, the lift sequence, and the response if something goes wrong. The lift director also verifies that pre-lift preparations, including equipment inspections and site controls, are complete.
A parallel requirement applies to assembly and disassembly. Under 1926.1404(d), the assembly/disassembly director must ensure before work begins that every crew member understands the tasks, associated hazards, and positions to avoid.12eCFR. 29 CFR 1926.1404 Assembly/Disassembly General Requirements New personnel joining mid-operation must receive the same briefing before taking on any task.
Keep the written plan and supporting documentation accessible at the job site throughout the operation. The operator must have rated capacity charts, operational procedures, and the manufacturer’s manual readily available in the cab at all times.3Occupational Safety and Health Administration. 29 CFR 1926.1417 – Operation Signal person qualification records must also be available on site while that person is working.10Occupational Safety and Health Administration. 29 CFR 1926.1428 – Signal Person Qualifications
Weather Thresholds
OSHA does not set a universal wind-speed cutoff. Employers must follow all manufacturer procedures applicable to the equipment’s operation.3Occupational Safety and Health Administration. 29 CFR 1926.1417 – Operation Manufacturer specifications typically include a maximum operating wind speed and a shutdown speed. The plan should record those thresholds, say who monitors wind during the lift, and set out how the crane and load will be secured if wind exceeds the limit.
Penalties for Skipping the Plan
Failing to develop a required plan, or ignoring its terms, can trigger significant OSHA penalties. As of the adjustment effective January 15, 2025, the maximum penalty for a serious violation is $16,550 per violation, and the maximum for a willful or repeated violation is $165,514 per violation.13Occupational Safety and Health Administration. OSHA Penalties A single multi-crane lift run without a plan can generate multiple citations if OSHA finds separate violations of the planning, personnel qualification, and ground condition requirements.
