Riggers Liability Insurance — insurance for a contractor's liability arising out of the moving of property and equipment that belongs to others, such as lifting air-conditioning units onto a roof with a crane. The standard commercial general liability (CGL) policy does not cover this risk due to the exclusion for "personal property of others in your care, custody or control." Riggers liability coverage can be effected by attaching a riggers liability endorsement to the CGL policy that modifies or deletes the "care, custody or control" exclusion. (Note that if the contractor is an insured under a builders risk policy on the project, coverage is usually provided in that policy for property of others for which the insured may be liable. The builders risk policy may include a deductible, however, and may not include coverage for loss of use.)
