A crane and rigging company’s total insurance cost typically runs 3-8% of annual revenue. For a contractor generating $3 million annually, that translates to roughly $90,000 to $240,000 per year across all required policies. These costs are baked directly into project pricing, so understanding them helps buyers evaluate whether a contractor is adequately covered.
The critical industry-specific policy is riggers liability insurance, which covers damage to property the contractor is actively lifting, moving, or installing. This fills the “care, custody, and control” gap that standard general liability excludes — if a rigging crew drops a $500,000 generator during installation, general liability will not cover the generator itself. Only riggers liability will. For a mid-size rigging company, riggers liability runs $15,000 to $40,000 per year depending on coverage limits and claim history.
Beyond riggers liability, key policies include commercial general liability ($1M/$2M occurrence/aggregate, typically $30,000-$60,000 per year for an industrial rigging firm), workers compensation (often the single most expensive line item, driven by high-risk NCCI class codes and the company’s experience modification rate), crane physical damage coverage (1-3% of each crane’s value annually), commercial auto for the fleet ($2,000-$5,000 per vehicle), and umbrella liability ($5,000-$10,000 per year for a $5M policy).
Client-imposed minimums drive coverage levels. Most industrial and commercial projects require at least $1M/$2M general liability and a $5M umbrella policy. Petrochemical and heavy industrial facilities often demand $10M to $25M in umbrella coverage. Contractor prequalification platforms like ISNetworld and Avetta require current certificates of insurance and EMR letters — an experience modification rate at or above 1.0 is a red flag for many major clients, and an EMR above 1.25 can disqualify a contractor entirely.
When evaluating rigging quotes, ask for a current certificate of insurance and verify the EMR. A properly insured contractor protects your project from liability exposure.
