The Care, Custody, and Control Problem
Commercial general liability covers property damage to someone else's property, but it excludes personal property in the care, custody, or control of the insured. The logic is that property you are handling is a different kind of risk from property you happen to be near, and it is intended to be insured elsewhere. For a rigging operation, that exclusion lands on the most valuable thing in the picture. A rooftop chiller being set, a transformer being placed, a steel truss being flown, a piece of production equipment being moved into a plant: while it is on the hook, it is in your care. Drop it, and the general liability policy likely does not respond to the damage to that unit. Riggers liability coverage, written as an inland marine form, fills that gap. It covers direct physical loss to property of others while in the insured's care, custody, or control during rigging, lifting, moving, and installation operations, typically while being hoisted, while suspended, and while being moved or set. Limits are usually set per occurrence with attention to the largest single item the contractor expects to handle. A related form, installation floater coverage, addresses materials and equipment the contractor is installing, including while in transit and at the job site before installation. The two overlap and are often written together.
- General liability excludes property in the insured's care, custody, or control
- The load on the hook is exactly that property, and it is usually the most valuable item on site
- Riggers liability covers physical loss to others' property during rigging and lifting
- Installation floater coverage addresses materials being installed, including in transit
Insuring the Crane Itself
The crane is the contractor's own property, and it is insured under contractors equipment coverage, also an inland marine form. A few details matter more here than in a general equipment schedule. Valuation first. Specialized lifting equipment has a thin secondary market and long replacement lead times. Actual cash value on an older crane can be far below what it costs to get an equivalent working machine, and replacement cost or an agreed value approach is often the better choice for primary units even at higher premium. Second, the rented and leased equipment question. Contractors routinely rent cranes and aerial equipment, and the rental agreement makes the renter responsible for damage, frequently at replacement cost, and also for continuing rental charges while a damaged unit is out of service. Coverage for rented equipment in your care, plus loss of use or rental reimbursement coverage, addresses both halves of that obligation. The second half is the one most often missing. Third, perils and conditions. Overturn and upset, collapse, damage during erection and dismantling, and damage in transit are the specific events to confirm rather than assume. Boom and jib damage sometimes carries its own treatment. And coverage during assembly and disassembly is worth a direct question, since that is a recognized high risk phase. Finally, business income. A contractor whose only large crane is down for four months has a revenue problem that physical damage coverage does not address. Loss of income or rental expense coverage for owned equipment is available and is worth pricing against the actual revenue that unit produces.
- Choose valuation deliberately, since depreciation on specialized lifting equipment can be severe
- Rented cranes need both damage coverage and loss of use or rental reimbursement coverage
- Confirm overturn, collapse, erection and dismantling, and transit coverage specifically
- Consider loss of income coverage for a primary unit whose downtime stops revenue
Liability, Contracts, and Who Carries the Risk
Lift operations are usually performed under a contract that allocates risk, and the allocation varies dramatically depending on whether the crane is supplied bare or with an operator. A bare rental, where the crane is provided without personnel, typically puts operational responsibility on the renter, and rental agreements reinforce that with indemnity running to the crane owner. An operated and maintained arrangement, where the crane comes with an operator, puts more responsibility on the crane company, and the contract often addresses whether the operator is a borrowed servant of the hiring contractor for liability purposes. That borrowed servant question is a recurring dispute and a reason to read the contract carefully rather than relying on industry custom. Either way, several insurance points follow. Confirm who is required to carry what and at what limits, and whether additional insured status and waiver of subrogation are required. Understand whether the contractual indemnity you are accepting is within what your liability coverage reaches, remembering that contractual liability is generally excluded and then given back in limited categories. And look at the umbrella and excess structure, because a lifting accident involving injury to multiple trades or damage to an occupied building can exceed a primary limit quickly. On the operational side, documentation is the defense. Lift plans for critical picks, documented ground and crane mat engineering, equipment inspection records, operator certification and qualification records, rigging inspection logs, and pre lift meetings all serve both safety and claims purposes. Underwriters in this class ask for them, and the quality of the answer affects terms.
- Bare rental and operated arrangements allocate risk very differently, as do their contracts
- The borrowed servant question for a supplied operator is a recurring dispute
- Confirm indemnity obligations are within what your liability coverage reaches
- Keep lift plans, ground engineering, inspection records, and operator certifications documented
Third Party Property Below and Around the Lift
The last piece is the exposure that has nothing to do with the load or the crane: the building, street, vehicles, utilities, and adjacent property in the zone of the lift. This is general liability territory, and it is where limits matter most. A boom contacting an energized line, a load swinging into a curtain wall, outrigger loading that damages a below grade structure, or a crane collapse into a neighboring property produce claims that combine property damage, bodily injury, and business interruption to third parties. Urban lifts over occupied buildings and active streets concentrate all of it. Three things deserve attention. First, limits and the excess tower, sized to the realistic worst case for the sites you work rather than to a contract minimum. Second, the subsidence and underground utility exposures, which some general liability forms restrict by endorsement in certain regions, so it is worth checking whether any such restriction applies to you. Third, permits and street closures, which often carry their own insurance requirements naming the municipality or transit authority, and those requirements need to be reviewed before the permit is accepted rather than after. Pre lift surveys of adjacent property, documenting existing condition with photographs, are inexpensive and routinely decisive. Neighbors attribute pre existing cracks to the lift, and the only effective answer is a dated record from before the work started.
- Third party property and bodily injury around the lift is general liability, where limits matter most
- Size the excess tower to the realistic worst case for your sites, not to a contract minimum
- Check for any endorsement restricting subsidence or underground utility exposure
- Document adjacent property condition with dated photographs before the lift
