Before a High-Value Lift: Compare the Load Value with Your Riggers Limit
Quick answer: The crane’s insured value and the value of the load are separate questions. Before lifting expensive machinery, compare the riggers liability wording, applicable limit, valuation basis and deductible with the property you will handle. A large general liability limit does not by itself establish coverage for a load in your care.
Define the entire assignment
Is the job only a lift, or does it include unloading, skidding, assembly, transport, storage and placement? Identify the moment you take custody and the moment the customer accepts the property. Send the actual scope and contract to the broker; a quote for “crane service” may not describe those additional operations.
| Value or exposure | Question to resolve |
|---|---|
| Replacement cost of the load | Which valuation basis and per-item limit apply? |
| Several components handled together | What is the maximum value exposed to one event? |
| Customer production delay | How are consequential loss and loss of use treated? |
| Borrowed rigging or rented equipment | Is damage to that equipment separately insured? |
Do not let the certificate substitute for endorsements
Ask for the relevant riggers coverage form and exclusions, not only an additional-insured certificate. Contractual responsibility can exceed insurance. A waiver or limitation in the service agreement also needs legal review; the broker's coverage review is not a substitute for that advice.
Check whether subcontracted work, unusual load types, storage or transport require specific approval. Where an increased limit is needed for a particular job, obtain confirmation of the effective dates and exact operation.
Keep safety and insurance decisions connected but distinct
OSHA's crane ground-condition standard addresses support conditions and responsibilities at the site. Ground assessment and the lift plan belong to qualified personnel. Insurance documentation should describe the operation accurately; it does not approve engineering, ground capacity or safe execution.
The pre-job file worth keeping
Retain the work order, property value evidence, condition photographs, scope, relevant contract terms and insurer confirmation. If the load or method changes, revisit the review before the revised lift. The most useful insurance discussion starts with the expensive thing that can be damaged and who is responsible for it at each stage.
