In plain language: Riggers Liability pays for damage to someone else's property while a rigging contractor is lifting, hoisting, or moving it with a crane or similar equipment. It fills the gap left when general liability excludes property in the contractor's care, custody, or control.
Technical definition: Riggers Liability is an inland marine coverage form that insures a rigging contractor's legal liability for third-party property damaged while being hoisted, lifted, lowered, or otherwise rigged. It responds despite the care, custody, or control exclusion found in standard commercial general liability policies and typically applies on a named-perils or all-risk basis.

Key Takeaways
- Riggers Liability covers a contractor's legal liability for damage to another party's property while that property is being hoisted, lifted, or moved during rigging operations.
- Agencies serving crane operators, steel erectors, or heavy haul contractors must confirm this coverage exists separately, since general liability almost always excludes property in the insured's care, custody, or control.
- The most common misunderstanding is assuming an umbrella or general liability policy will drop down to cover a dropped load; it typically will not because the exclusion follows through to the umbrella.
- A quick win for agencies is to ask every rigging or crane prospect one direct question: "What happens to the item you're lifting if the cable snaps?"
What Is Riggers Liability in Insurance?
Riggers Liability is a specialized inland marine coverage built to solve a problem that general liability policies were never designed to fix. Standard CGL policies exclude damage to property in the insured's care, custody, or control, under the legal theory that a bailee relationship, not a liability relationship, governs that exposure. A crane operator lifting a client's HVAC unit onto a rooftop has physical control over that unit for the duration of the lift, which triggers the exclusion precisely when the risk of dropping it is highest.
Riggers Liability exists because the gap between "legal liability" and "property in your control" is where crane and rigging work actually happens. The policy insures the contractor's legal responsibility, meaning the insured must typically be found negligent or liable under common law or contract for the coverage to respond. A steel erector who drops a prefabricated beam while swinging it from a flatbed to a building frame, damaging both the beam and a parked vehicle below, needs Riggers Liability to cover the beam itself and standard CGL to cover the vehicle.
Coverage structure varies by carrier. Some policies write on a named-perils basis, listing causes of loss like overturning, collision, or dropping. Others write broader all-risk language subject to standard inland marine exclusions like wear and tear, inherent vice, or mechanical breakdown. Limits are typically scheduled per occurrence and sometimes per lift, which matters enormously for contractors moving high-value items like transformers, generators, or precast concrete.
How Does Riggers Liability Work?
- The lift begins. A rigging contractor takes physical control of a third party's property to hoist, lower, or move it as part of a job.
- The incident occurs. Something goes wrong during the lift, such as a rigging failure, operator error, or equipment malfunction, causing damage to the lifted property or nearby property.
- The exclusion applies. The contractor's general liability carrier denies the claim for the lifted item itself, citing the care, custody, or control exclusion.
- The riggers policy responds. The Riggers Liability policy, triggered by the contractor's legal liability for the damaged property, adjusts and pays the claim up to the scheduled limit.
- The resolution. The property owner is made whole, the contractor avoids an uninsured loss, and any separate third-party property damage is handled under the standard CGL policy.
Real Claim Examples Involving Riggers Liability
Rooftop HVAC unit dropped during installation
A commercial crane contractor was hired to lift a 4-ton rooftop HVAC unit onto a three-story office building. A rigging strap failed mid-lift, and the unit fell forty feet, destroying the equipment and damaging a section of the building's parapet wall. The contractor's CGL policy denied the claim for the HVAC unit under the care, custody, or control exclusion, but the Riggers Liability policy covered the unit's replacement cost, while CGL picked up the parapet wall damage as third-party property not in the contractor's control.
Transformer damaged during substation relocation
A rigging company was moving a utility transformer between substations when the lifting cable overturned the load, cracking the transformer housing and causing an oil leak. The utility company held the rigger liable for the full replacement cost, exceeding $200,000. Riggers Liability responded because the transformer was in the contractor's care, custody, and control at the moment of failure, and the policy's scheduled limit was sufficient to cover the loss.
Precast panel chipped during tilt-up construction
A steel and concrete erector was lifting a precast concrete wall panel into place on a tilt-up warehouse project when the panel struck a support brace, chipping a corner and cracking an embedded anchor plate. The general contractor demanded repair or replacement. Riggers Liability covered the panel damage, but the claim also revealed the contractor's policy excluded damage caused by defective rigging equipment, creating a coverage dispute that delayed payment by several weeks.
Riggers Liability vs. Contractors Equipment Floater: What Is the Difference?
Riggers Liability and a Contractors Equipment Floater are both inland marine products, but they protect different property. Riggers Liability covers third-party property being lifted or moved, while a Contractors Equipment Floater covers the insured's own tools, machinery, and equipment used on the job, including the crane or rigging gear itself.
| Comparison area | Riggers Liability | Contractors Equipment Floater |
|---|---|---|
| Primary use case | Damage to others' property during hoisting or rigging operations | Damage to the insured's own owned, leased, or rented equipment |
| Coverage / concept type | Third-party legal liability coverage | First-party property coverage |
| Typical exclusions | Mechanical breakdown, wear and tear, inherent vice, overloading beyond rated capacity | Wear and tear, mechanical breakdown, employee theft in some forms, mobile equipment licensed for road use |
| Who is most affected by errors | The property owner whose item was being lifted | The contractor who owns the damaged equipment |
| Common mistakes | Assuming CGL covers lifted property; underinsuring high-value lifts | Confusing rented equipment with owned equipment; missing rented equipment coverage extensions |
What Are the Most Common Mistakes With Riggers Liability?
- Agencies assume general liability or an umbrella policy will cover dropped loads, missing that the care, custody, or control exclusion flows through to excess layers, leaving the client uninsured for the exact loss they were worried about.
- Producers quote a flat limit without asking about the value of individual lifts, resulting in a $500,000 transformer loss against a $250,000 per-occurrence limit.
- CSRs fail to confirm whether the form is named-perils or all-risk, which changes whether a loss like overloading or operator error is actually covered.
- Agencies overlook the exclusion for property while in transit by land, air, or water when the rigging operation includes a trucking leg, requiring a separate motor truck cargo or transit policy.
- Renewal reviews skip verifying that scheduled equipment and lift capacities still match the contractor's current fleet and job scope, especially after the client adds larger cranes or takes on heavier lifts.
- Agents describe Riggers Liability as "covering the crane," when it actually covers the liability for the item being lifted, not the crane itself, which needs its own equipment floater.
How to Explain Riggers Liability to a Client
Explaining Riggers Liability to a personal lines client
Riggers Liability rarely applies to personal lines clients directly, but it matters when a homeowner hires a crane service to move something heavy, like a hot tub or a boat. A CSR can explain that the contractor doing the lift should carry their own Riggers Liability coverage, and it's worth asking for proof of that coverage before the job starts, the same way you'd ask a roofer for proof of liability insurance.
Explaining Riggers Liability to a small business owner
Riggers Liability steps in for the exact moment your crane or rigging equipment has someone else's property hanging in the air. Your general liability policy won't pay if you drop that customer's generator or transformer, because it's considered to be in your care, custody, or control at that moment. This coverage is built specifically to close that gap so one bad lift doesn't put your business at financial risk.
Explaining Riggers Liability to a CFO or risk manager
Riggers Liability addresses a structural exclusion in your general liability program, not a coverage gap you created through error. Any lift involving third-party property, whether equipment relocation, machinery installation, or structural steel placement, carries uninsured exposure unless Riggers Liability is scheduled with limits matched to your highest-value single lift. I'd recommend we review your loss runs for near-misses and confirm the per-occurrence limit reflects current project scope, not last year's.
Frequently Asked Questions About Riggers Liability
Does Riggers Liability cover damage to the crane itself?
No, Riggers Liability covers third-party property being lifted or moved, not the contractor's own crane or rigging equipment. Damage to the crane itself is typically covered under a Contractors Equipment Floater or Inland Marine Equipment Floater, which is a separate policy or endorsement.
Is Riggers Liability the same as Bailee's Customer Insurance?
No, they're related but distinct. Bailee's Customer Insurance covers property belonging to customers while it's in the insured's physical possession for service, storage, or repair, while Riggers Liability specifically addresses property damage occurring during the act of hoisting, lifting, or rigging, often with different perils and limit structures suited to that exposure.
Why does general liability exclude property being rigged?
General liability excludes property in the insured's care, custody, or control because that type of exposure is considered a bailment risk rather than a third-party liability risk, and it's historically been carved out and priced separately through inland marine products like Riggers Liability. Carriers view ongoing physical control over property as a different risk profile than incidental contact that causes bodily injury or property damage to bystanders.
Can Riggers Liability be written as part of a CGL policy?
Riggers Liability is almost always written as a separate inland marine policy or endorsement rather than built into a standard CGL form, because CGL forms are structured around liability exposures, not property-in-transit or property-in-control exposures. Some carriers offer it as a scheduled endorsement attached to an inland marine program alongside other mobile equipment and contractor coverages.
What causes of loss are typically excluded under Riggers Liability?
Common exclusions include mechanical breakdown of the lifting equipment, wear and tear, inherent vice in the property being lifted, and overloading beyond the rated capacity of the rigging equipment. Policies vary by carrier, so agencies should review the specific form language rather than assume uniform exclusions across markets.
How are limits typically structured for Riggers Liability?
Limits are usually set on a per-occurrence basis and sometimes capped per lift, which means agencies should match the limit to the highest-value single item the contractor expects to handle, not an average job value. A contractor who occasionally moves million-dollar transformers needs a limit reflecting that peak exposure, even if most jobs involve far less valuable property.
Related Insurance Terms
- Care, Custody, or Control Exclusion: A standard CGL exclusion that removes coverage for property the insured is physically possessing, controlling, or working on, which creates the exact gap Riggers Liability is designed to fill.
- Bailee's Customer Insurance: Coverage for customer property held by a business for repair, service, cleaning, or storage, similar to Riggers Liability but focused on possession rather than active lifting or hoisting.
- Inland Marine Insurance: The broader coverage category that includes Riggers Liability, Contractors Equipment Floaters, and other property-in-transit or specialized mobile property forms.
- Contractors Equipment Floater: A property policy covering the insured's own construction equipment, distinct from Riggers Liability, which covers third-party property instead of the contractor's own tools and machinery.
- Ocean Marine Insurance: A related coverage line for rigging operations occurring at ports, docks, or aboard vessels, where Riggers Liability exposures sometimes overlap with marine cargo and stevedoring liability.
- Motor Truck Cargo Insurance: Coverage for property while being transported by truck, which often needs to be paired with Riggers Liability when a rigging job includes a transit leg not covered under the rigging form itself.
