Stage rigging equipment must be inspected annually, or immediately following any circumstance which could result in possible equipment damage or failure.  Any modification of existing equipment, or installation of new equipment, must be inspected to ensure that these changes meet current safety standards.  We have long advocated for annual inspections.  Our Inspection & Preventive Maintenance program has set a high standard for our industry.  Annual inspections include staff training to acquaint system operators with proper care and maintenance of their equipment.
