Unsupported Excess Liability Program

High-Limit Protection for Crane, Steel Erection & Millwright Operations.

Quick Links

Heavy lifting and high-risk operations require more than primary coverage, you need strong excess protection built for the unique exposures of crane rental, steel erection, and millwright businesses. Our Unsupported Excess Liability Program provides additional limits over GL, Auto, and Workers’ Compensation to ensure your clients have the protection they need on demanding jobs and complex project sites.

Designed for contractors who operate cranes (with or without operators), lift heavy materials, or perform installation and millwright work, this program delivers the extra layer of coverage required by project owners, GCs, and contract agreements.

If your work involves elevated risks, heavy machinery, critical lifts, or structural installation, excess liability is essential.
