This class is one tier of our Qualified Rigger & Signal Person Training, which qualifies riggers and signal persons together in one day.
What Qualified Rigger Level II Actually Covers
Qualified Rigger Level II is not Level I with a longer class. It is a different job. A basic rigger executes routine, pre-engineered picks where the configuration is already decided. The Level II rigger is the person who decides that configuration. He looks at an awkward, off-center, multi-thousand-pound load and works out where the hook goes, what gear carries it, and what each leg will actually feel at angle.
He also decides whether the lift is routine at all, or whether it needs to be engineered. This is the lead rigger on the crew. When the pick stops being a textbook example, the foreman turns to him.
The Level II rigger owns the parts of rigging that involve real calculation and real consequence. That means locating the center of gravity on an irregular load, resolving sling tension at the working angle, distributing load across a two- or four-point pick, sharing a load between two cranes, and reading the load chart and capacity math that tell you whether the plan sits inside the envelope or over it. Level II also moves the rigger up the hardware ladder.
He works with engineered below-the-hook lifting devices, spreader and equalizer beams, plate clamps, swivel hoist rings, and load-rated synthetic and alloy assemblies that a basic pick rarely touches.
Level II builds directly on Level I. A solid command of sling working load limits, hardware inspection, hitch types, and basic load estimation is assumed walking in. If your people have not been formally qualified at the basic level yet, start with our Qualified Rigger Training (Levels I & II) pathway. This page is the advanced tier of that same program, built for crews ready to lead lifts rather than just hook them.
- Level I executes routine, pre-engineered lifts; Level II designs and leads complex and non-routine ones
- Core skills: center of gravity, sling-angle tension, multi-point load distribution, multi-crane lifts, load-chart math
- Advanced hardware: spreader/equalizer beams, plate clamps, swivel hoist rings, engineered below-the-hook devices
- Assumes a working command of Level I material as the foundation
Where Level II Lives in OSHA’s Qualified-Rigger Requirement
OSHA does not write the words “Level I” or “Level II” into the standard. Those tiers come from how the industry organizes rigger competence, not from the regulation. What OSHA requires is that a qualified rigger be used during crane assembly and disassembly, and whenever workers are in the fall zone hooking, unhooking, or guiding a load, or making the initial connection of a load. That requirement comes out of 29 CFR 1926.1404 and runs throughout OSHA’s Cranes & Derricks standard for construction.
Level II matters under that framework because of the definition itself. OSHA defines a qualified rigger as a rigger who meets the criteria for a qualified person — someone who has successfully demonstrated the ability to solve problems related to rigging loads. The operative word is problems. A routine, pre-engineered pick is not much of a problem to solve. An off-center vessel that has to be turned in the air is.
So is a structural module lifted on four legs of unequal length, or a load shared between two machines. An employer who puts a basic rigger on that work has arguably not met the “demonstrated ability to solve problems” bar for the problem actually in front of him. Level II is how you document that your lead rigger can solve the hard ones.
OSHA’s general rigging-equipment rules in 29 CFR 1926.251 sit underneath all of this. They cover sling rating, inspection, removal from service, and the requirement that rigging be selected and used within its capacity. A Level II rigger has to know those rules cold. At the advanced level the loads are heavier, the angles are steeper, and the margin for a derated sling or an undersized shackle is far thinner.
- OSHA requires a qualified rigger; the Level I/II split is an industry competence model, not regulatory text
- The standard turns on demonstrated ability to solve rigging problems — complex picks are where that bar bites
- 1926.251 governs sling rating, inspection, and use within capacity — non-negotiable at Level II loads
- Level II documents that your lead rigger can handle the non-routine work a basic rigger should not
Center of Gravity, Sling Tension, and the Math a Level II Rigger Owns
This is the heart of Level II, and it is where most of the class time goes. A basic rigger can run a balanced load on a simple hitch. A Level II rigger has to handle the load that isn’t balanced and the angles that aren’t forgiving. That means working real numbers, not eyeballing it.
Center of gravity. Hook directly over the center of gravity and a load lifts level and predictable. Get it wrong and the load tips, swings, or shock-loads a leg the instant it leaves the ground. Level II teaches candidates to find the center of gravity on an irregular or unevenly weighted load.
They learn to calculate it from known component weights and dimensions, to use the proportional method when the end weights are known, and to recognize the warning signs of a high or shifted CoG that makes a load want to roll. The rigger learns to place the hook over the CoG and to choose sling lengths that keep the load level.
On tippy loads he learns to keep the CoG below the lift point, so the pick stays stable instead of trying to capsize.
Sling angle and tension. The single most misunderstood number in rigging is what the sling actually carries. As the angle from horizontal drops, the tension in each leg climbs fast. A leg at 60 degrees carries noticeably more than the share you would guess. At 45 degrees it carries more again. At 30 degrees the tension roughly doubles the vertical share. Level II riggers learn to compute leg tension using the load angle factor, or the sling-length-over-vertical-height method.
They learn why a low choke angle can quietly overload a sling that “looks” big enough, and how to keep included angles out of the danger zone. They also work the D/d ratio — how a sharp bend over a small-diameter pin or edge derates a sling — and the sling-to-load bearing geometry that decides whether a synthetic sling survives the pick.
Load distribution on multi-point picks. On a two-point lift, the load does not split evenly unless the center of gravity sits exactly in the middle. It loads the nearer pick point harder. Level II teaches the rigger to calculate how a load distributes across two or four attachment points based on CoG location. He sizes each leg and each piece of hardware for the share it actually carries, not the average.
He also learns that on a four-leg bridle you generally cannot assume all four legs share equally — two may carry the load while two only steady it. Reading the crane’s load chart against these real per-leg numbers is the final check that keeps the whole system inside its rated capacity.
- Center of gravity: locate it on irregular loads, place the hook over it, keep tippy loads stable
- Sling-angle tension: compute leg tension by load-angle factor; understand why low angles overload gear
- D/d ratio: derate slings for sharp bends over pins and edges
- Multi-point distribution: size each leg for its real share, not the average; respect uneven four-leg loading
Multi-Crane (Tandem) Lifts and Engineered/Critical Lifts
This section is the dividing line between a good rigger and a Level II rigger. The picks here are the ones that show up in an incident report when they are done wrong.
Multi-crane and tandem lifts. When one machine cannot reach, cannot see the whole pick, or cannot carry the load alone, two or more cranes share it. The rigging problem then gets dramatically harder. The load does not split 50/50 unless the geometry is perfect. The center of gravity, the sling lengths, and the relative crane positions decide how the share moves between machines — and that share changes as the load is rotated, tailed, or up-ended.
Level II riggers learn how load shifts between cranes during the lift. They learn why each crane on a tandem pick is typically de-rated to a fraction of its single-machine chart capacity to absorb that uncertainty, and why the picking points and sling lengths have to be planned so neither crane gets overloaded mid-rotation. They also learn why these lifts demand a dedicated qualified signal person and one lift director in unambiguous control.
A multi-crane lift with two riggers freelancing is how loads get dropped.
Engineered and critical lifts. Some picks cross a threshold where judgment alone is not enough and the lift has to be engineered — planned in writing, calculated, and signed off before anyone lifts. Common triggers include loads at a high percentage of the crane’s rated capacity, multi-crane lifts, lifts over occupied space or live process equipment, personnel-handling considerations, and unusually heavy, expensive, or one-of-a-kind loads. A Level II rigger is the person who recognizes when a pick has crossed that line.
He can read, contribute to, and execute a documented lift plan: confirming the load weight and CoG, verifying every component of the rigging against its rated capacity with the correct design factor, checking sling angles and below-the-hook device ratings, and confirming the crane configuration and ground conditions support the plan. He does not have to be the engineer. But he has to be fluent enough to catch a plan that is wrong before it becomes a statistic.
This is exactly the kind of high-consequence judgment that also makes a strong candidate for the employer-based train-the-trainer role.
- Tandem lifts: understand load share between cranes, mid-lift shift, per-crane de-rating, and single-point control
- Critical-lift triggers: high % of capacity, multi-crane, over occupied/live areas, personnel, essential loads
- Lift plans: read and execute an engineered plan — verify weight, CoG, gear capacity, angles, and configuration
- The Level II rigger recognizes when a pick must be engineered and can catch a flawed plan before the lift
Advanced Hardware and Below-the-Hook Lifting Devices
Level II loads frequently cannot be rigged with a sling and a shackle alone. The advanced rigger has to be fluent in the engineered hardware that makes hard picks possible — and in inspecting and rejecting it. Every one of these devices is load-rated. Using one outside its rating, its design configuration, or its inspection criteria is exactly the failure mode Level II is meant to prevent.
Spreader and equalizer beams are the most important family. A spreader beam takes a single hook load and spreads it to two or more vertical pick points. It keeps the slings vertical so the load is not crushed inward and the legs are not overloaded by angle, which is critical for long, slender, or top-loaded items. An equalizer beam does something different.
It lets a load share more evenly between two crane lines or two pick points, balancing the share as geometry shifts. Level II riggers learn the difference between the two. They learn to read the beam’s rated capacity and its rated pick-point spacing, and never to substitute one for the other or improvise a beam out of unrated steel.
Lifting beams, plate and beam clamps, swivel hoist rings, eye bolts (and why a swivel hoist ring beats a shoulder eye bolt for angled loading), turnbuckles, load-rated shackles, and synthetic and alloy-chain assemblies round out the kit.
The inspection discipline scales up with the hardware. A Level II rigger inspects and rejects engineered devices to their own criteria. He looks for bent or cracked beams, distorted or worn lugs, damaged threads on hoist rings, and illegible or missing rated-capacity markings. He understands that a below-the-hook device with no legible rating tag is out of service, full stop.
The same OSHA 1926.251 logic that governs slings applies to every piece of this hardware: rate it, inspect it, remove it from service when it is damaged, and never exceed capacity. The stakes are just higher, because the loads are bigger.
- Spreader beam: keeps slings vertical, protects slender/top-loaded items, prevents angle overload
- Equalizer beam: balances load share between two lines or pick points as geometry shifts
- Swivel hoist rings, plate clamps, load-rated shackles, alloy chain, turnbuckles: the engineered-pick toolkit
- Inspection scales up: reject damaged or unmarked devices; no legible rating tag means out of service
The Level II Exam: Calculation-Heavy Written Plus a Lead-Rigger Practical
A Level II qualification has two halves, and the bar on each is meaningfully higher than Level I. A candidate must pass both.
The written portion is where Level II earns its name, because it is calculation-heavy. Expect to work problems, not just recall facts. You will resolve sling tension at a given angle, locate the center of gravity from component weights and dimensions, distribute a load across two and four pick points, apply D/d derating, size gear with the correct design factor, and read a load chart against the real per-leg numbers a pick produces.
The written exam also covers the knowledge layer around the math: below-the-hook device selection and rating, spreader-versus-equalizer-beam application, multi-crane lift principles, critical-lift planning triggers, and the OSHA rigging rules in 1926.1404 and 1926.251. A candidate who memorized sling capacities for Level I but cannot compute tension at 45 degrees does not pass Level II.
The practical portion puts the candidate in the lead-rigger seat. Under observation, he takes a non-routine load and plans it. He determines or verifies the weight, locates the center of gravity, selects the rigging and any below-the-hook device for the actual load and angles, calculates the per-leg tension, inspects and rejects gear to criteria, rigs the pick, sets tag lines, and directs the lift with correct communication and signals.
The evaluation is built around the kind of awkward, off-center, multi-point load a Level II rigger is supposed to lead — not a balanced box on a single sling. The candidate has to demonstrate judgment, not just technique. He has to recognize when a load needs a spreader beam instead of a steeper sling angle, when a pick has crossed into critical-lift territory, and when to stop and re-plan.
- Written: work tension, CoG, load-distribution, D/d, and design-factor problems — plus device, beam, and tandem-lift knowledge
- Practical: plan and lead a non-routine pick — weight, CoG, gear selection, per-leg tension, inspection, rigging, signals
- Both must be passed; the bar is judgment-and-calculation, not recall
- The practical load is built to be complex and off-center, reflecting what a lead rigger actually faces
Prerequisites, How Long Level II Lasts, and When to Requalify
Level II prerequisites are stricter than Level I in one way that matters: you need to own the Level I material going in. A candidate who cannot yet identify and inspect slings and hardware, estimate load weight, read a capacity tag, and rig the basic hitches is not ready to build CoG and tension math on top of that foundation. The advanced content will outrun him.
We routinely qualify riggers through Level I first and then stack Level II in the same engagement. That is the cleanest path for a crew leveling up its lead riggers.
Beyond the Level I foundation, the practical requirements are the realities of leading heavy lifts. Candidates must be at least 18 years of age. They must be physically capable of rigging work — handling heavy gear and below-the-hook devices, working around suspended loads, and maintaining the situational awareness a lead rigger needs. They must be able to meet the medical, physical, and substance-abuse testing requirements their employer and the jobsite enforce, since fall-zone work is safety-sensitive.
Because Level II is genuinely calculation-driven, candidates should be comfortable with practical shop math: multiplication, division, ratios, basic trigonometry concepts (or the angle-factor tables that stand in for them), and reading a tape measure accurately. English-language comprehension sufficient to read load charts, sling and device rating tags, and written lift plans is necessary for both safe performance and the written exam.
- Working command of Level I is the real prerequisite — we can stack Level I first if needed
- Minimum age 18; physically able to handle heavy gear and lead lifts safely
- Able to meet employer/jobsite medical, physical, and drug-testing requirements
- Comfortable with practical shop math and angle factors; able to read charts, tags, and lift plans
How long Level II lasts and when to requalify. OSHA does not stamp a hard expiration date on qualified-rigger status the way it does on operator certification. But the duty to keep a Level II rigger current is real — arguably more so than at Level I, because the consequences of drift on complex lifts are larger.
The industry practice 3P Safety recommends and builds toward is requalification every three to five years, with three years being the conservative, audit-friendly benchmark that most safety programs adopt. Many employers sync rigger requalification with their operator and signal-person cycles so the whole lift crew renews on one calendar.
For a Level II rigger specifically, event-based re-evaluation matters even more than the calendar. Requalify after any rigging-related incident or near-miss. On a critical or multi-crane pick, treat a near-miss as a hard trigger, not a judgment call. Requalify after a documented performance concern, after observed unsafe practice on a complex lift, and when a rigger returns to lead-rigging duties after an extended absence from that level of work. Standards, hardware, and below-the-hook device designs evolve.
A requalification is a fresh demonstration that your lead rigger still calculates correctly, still inspects engineered gear correctly, and still leads the hard pick correctly under observation. On the loads a Level II rigger handles, that fresh demonstration is cheap insurance.
- Recommended requalification every 3 years (5 years maximum under most program policies)
- Treat any near-miss on a critical or multi-crane lift as a hard requalification trigger
- Requalify after a performance concern, observed unsafe practice, or return to lead-rigging duties
- Sync with operator and signal-person cycles to keep the lift crew’s records on one calendar
How 3P Safety Delivers Level II — Your Jobsite or Our Partner Yard in Goldsboro
We run Qualified Rigger Level II in the same two formats as the rest of our curriculum, and you pick the one that fits your operation. Format one is training at our crane operator school in Goldsboro, NC. Your people come to 309 N William St. We provide the rigging gear, the below-the-hook devices, the loads, the classroom, and the practical setup.
They work the calculations, put hands on spreader beams and engineered hardware, and run the written and practical evaluation on real, off-center loads before anyone signs off. This is the efficient path for one or two lead riggers, or for a contractor who wants people trained off the clock and away from jobsite distractions.
Format two is employer-based training on your jobsite — anywhere in the U.S. and OCONUS. We bring Level II to you and build the practical around your equipment, your typical loads, and your real rigging geometry. For a crew leveling up its lead riggers, this is almost always the better value. There is no travel or lodging for your people, no downtime sending them away, and a practical evaluation that mirrors the exact complex picks they run.
Employer-based delivery also feeds naturally into employer-based crane training and train-the-trainer, so a strong Level II rigger can become the in-house evaluator who keeps your rigging pipeline qualified between engagements.
Either way, the sequence is the same and the practical is real: advanced prep instruction → worked calculations → hands-on with engineered hardware → calculation-heavy written exam → lead-rigger practical demonstration → documented Level II qualification. We do not run a slideshow and hand out paper. People compute tension and center of gravity, rig real picks with real below-the-hook devices, and lead a complex lift under observation before they are deemed qualified. Riggers leveling up often stack companion credentials in the same trip.
A qualified signal person certification and an overhead crane operator certification are common pairings, so one worker can rig, signal, and run the machine.

Who Needs Level II Riggers — and Why Train Them With 3P Safety
Wherever the picks get heavy, off-center, or complex, you need at least one Level II rigger on the crew — the person who can lead the lift the basic riggers should not. The advanced fundamentals carry across every job: center of gravity, sling-angle tension, multi-point distribution, engineered hardware, and critical-lift judgment. They apply whether the load is a 40-ton vessel, a precast double-tee, a turbine, or a structural steel module.
Typical audiences include structural steel erectors and ironworkers running multi-point and tandem picks, heavy-civil and bridge contractors, industrial and plant-maintenance teams setting heavy machinery, millwrights and machinery movers, precast and tilt-up concrete crews handling long, top-heavy panels, shipyard and marine fabrication shops, oil, gas, and petrochemical turnaround crews lifting vessels and exchangers, power generation and utility teams, wind-energy technicians handling blades and nacelles, and military and federal contractors running engineered lifts stateside or OCONUS.
Lead riggers on these crews almost always hold companion crane credentials. We routinely stack the same person’s qualified signal person and operator certifications, so a single experienced hand can plan the pick, rig it, signal it, and run the machine. That is exactly the cross-trained lift crew these operations need. Compare every class in our rigging training lineup, or start from our crane & rigging training home to see how the rigger, signal-person, and operator credentials fit together.
- Structural steel, ironwork, bridge, and heavy-civil construction running multi-point and tandem picks
- Industrial maintenance, millwrighting, and heavy machinery moving
- Precast/tilt-up concrete, shipyards, and marine fabrication
- Petrochemical turnarounds, power, utilities, and wind energy
- Military and federal contractors running engineered lifts, including OCONUS
3P Safety Crane & Rigging Training is founder-led by Patrick Salazar, and at the Level II tier that matters more than anywhere else in the curriculum. The advanced content is judgment-and-calculation work that should come from someone who has actually planned and led complex picks. Patrick is an NCCCO-certified mobile crane operator (LBC/TLL/TSS) and tower crane operator, a certified crane inspector, and a lift director, and he holds OSHA 500 outreach-trainer status.
When your lead rigger asks how a load shifts between two cranes mid-rotation, why a spreader beam beats a steeper sling angle on a slender load, or how to find the center of gravity on something that will not sit level, he gets the answer from someone who has stood at the hook on real iron — not someone reading from a binder.
We are built to come to you. From our partner yard in Goldsboro we serve crews nationwide and OCONUS, bringing the same field-credentialed Level II instruction to a jobsite in California, Texas, or Florida that we deliver in North Carolina. We run a real practical on real off-center loads with real below-the-hook devices — not a lecture-only certificate.
We reference qualification to recognized authorities, including NCCCO and OSHA’s published standards, so the documentation you keep holds up to a general contractor’s safety team or an OSHA compliance officer. Level II is one piece of a complete crane-and-rigging program. You can stack it with signal-person, operator, inspection, and train-the-trainer work in a single coordinated engagement.
- Founder-led and field-credentialed — Level II instruction from a working crane operator, inspector, and lift director
- Nationwide and OCONUS reach — we travel to your jobsite and build the practical on your gear and loads
- Real lead-rigger practical — off-center loads and engineered hardware, not a lecture-only certificate
- Part of a complete program — stack rigger, signal-person, operator, inspection, and train-the-trainer in one engagement
Frequently Asked Questions
What is the difference between Qualified Rigger Level I and Level II?
Level I (Basic Rigger) covers routine, pre-engineered lifts where the configuration is already decided: identifying and inspecting slings and hardware, estimating load weight, reading capacity tags, and rigging standard hitches. Level II is the advanced tier for the lead rigger who designs and leads the complex pick.
It adds real calculation and judgment — locating the center of gravity on irregular loads, resolving sling tension at angle, distributing load across two- and four-point picks, sharing a load between cranes, planning and executing engineered/critical lifts, and using below-the-hook devices like spreader and equalizer beams. A solid command of Level I material is expected before moving into Level II.
Does OSHA require a Level II rigger specifically, or just a qualified rigger?
OSHA’s standard requires a qualified rigger; the Level I/II split is an industry competence model, not regulatory language. But the distinction has teeth. OSHA defines a qualified rigger as someone who has demonstrated the ability to solve problems related to rigging loads, and a complex, off-center, multi-crane, or engineered pick is exactly the kind of problem a basic rigger should not be leading.
Putting an unqualified rigger on that work arguably fails the ‘demonstrated ability to solve problems’ standard for the problem actually in front of them. Level II is how an employer documents that its lead rigger can handle the non-routine and critical lifts that a Level I qualification doesn’t cover.
How does sling angle affect the load each leg carries on a Level II pick?
Dramatically, and it’s the number riggers most often get wrong. The lower the angle of a sling leg from horizontal, the more tension that leg carries for the same load. A leg at 60 degrees carries more than its straight vertical share, at 45 degrees more again, and at 30 degrees the tension roughly doubles the vertical share — which can quietly overload a sling that looks plenty big enough.
Level II riggers learn to compute leg tension using the load-angle factor (or the sling-length-over-vertical-height method), to keep included angles out of the danger zone, and to recognize when a spreader beam to keep the slings vertical is safer than accepting a steep, high-tension angle. That calculation, not a guess, is what keeps the gear inside its rated capacity.
What makes a lift a ‘critical lift,’ and does a Level II rigger plan it?
A lift is typically treated as critical when it crosses a higher-risk threshold — common triggers include loads at a high percentage of the crane’s rated capacity, multi-crane (tandem) lifts, lifts over occupied space or live process equipment, personnel-handling considerations, and unusually heavy, expensive, or one-of-a-kind loads. A Level II rigger is the person who recognizes when a pick has crossed that line and needs to be engineered and planned in writing.
They don’t necessarily write the engineering, but they must be fluent enough to read, contribute to, and execute the lift plan — verifying the load weight and center of gravity, checking every rigging component against its rated capacity and design factor, confirming sling angles and below-the-hook device ratings, and catching a flawed plan before the lift happens.
How do multi-crane (tandem) lifts change the rigging problem?
A tandem lift is one of the hardest problems a Level II rigger handles. When two cranes share a load, it does not split 50/50 unless the geometry is perfect — the center of gravity, the sling lengths, and the relative crane positions decide how the share moves between machines, and that share changes as the load is rotated, tailed, or up-ended.
Because of that uncertainty, each crane on a tandem pick is typically de-rated to a fraction of its single-machine chart capacity, the picking points and sling lengths are planned so neither crane is overloaded mid-rotation, and the lift runs under one lift director and a dedicated qualified signal person in unambiguous control. Level II teaches the rigger to understand that load share and shift so the plan stays inside both cranes’ capacity throughout the pick.
Can 3P Safety train our lead riggers to Level II at our own jobsite?
Yes. Employer-based, on-site delivery is one of our two core formats, and for a crew leveling up its lead riggers it’s usually the better value. We bring Level II to your jobsite anywhere in the U.S. and OCONUS, build the practical around your own equipment, below-the-hook devices, and typical complex loads, and run the calculation-heavy written and lead-rigger practical evaluation in your environment — no travel or lodging for your people and no downtime sending them away.
Smaller groups often prefer to come to our partner yard in Goldsboro, NC, where we provide the gear, the engineered hardware, and the loads. If your riggers need Level I first, we can stack it ahead of Level II in the same engagement. Call (252) 274-0583 or request a quote to scope it.
