Live Event Stage Rigging Inspection Checklist

Verify that the truss load calculations are available on site and signed by a qualified structural engineer, accounting for all dynamic and static loads. (ANSI E1.1-2022 Section 9)

Confirm that the truss span does not exceed the manufacturer's specified limits for the applied load. Measure and document the span. (Manufacturer's Specifications)

Inspect all truss connection hardware (bolts, pins, couplers) for damage, corrosion, and proper installation. Verify correct grade and size. (ANSI E1.1-2022 Section 7)

Assess the roof structure's load-bearing capacity. Ensure it is adequate for the intended rigging loads, considering point loads and distributed loads. (Local Building Codes)

If using ballast weights, verify the weight and securement method. Ensure they are properly rated and positioned to prevent tipping. (Best Practices)

For ground-supported structures, check the stability of the base. Ensure proper leveling and anchoring to prevent movement. (ANSI E1.21-2013)

Evaluate the structure's resistance to wind and weather conditions. Implement appropriate measures for stabilization in adverse weather. (Local Weather Guidelines)

Visually inspect all truss sections for signs of bending, cracking, or other structural damage. Remove any damaged sections from service. (ANSI E1.1-2022 Section 8)

Review all relevant documentation, including structural calculations, load charts, and inspection reports. Ensure they are current and accurate. (ANSI E1.1-2022 Section 5)

Verify that the rigging does not obstruct emergency exits or fire suppression systems. Maintain clear pathways for evacuation. (NFPA 101)

Verify that the chain motor's load rating meets or exceeds the weight of the suspended load, including a safety factor of at least 5:1. (ANSI E1.6-1-2012)

Inspect the chain for wear, damage, and proper lubrication. Replace any chain with damaged or worn links. (ANSI E1.6-1-2012)

Test the upper and lower limit switches on each chain motor to ensure they function correctly. (ANSI E1.6-1-2012)

Verify the proper functioning of the chain motor's brake system. Ensure it holds the load securely when power is removed. (ANSI E1.6-1-2012)

Inspect all electrical connections for tightness and proper grounding. Ensure cables are protected from damage and strain. (NFPA 70)

Verify that the hoist suspension points are adequately rated and securely attached to the supporting structure. (ANSI E1.6-1-2012)

Inspect the chain bag for damage and proper attachment. Ensure it can adequately contain the chain without interference. (Best Practices)

Test the chain motor control system for proper operation, including individual and group control functions. (ANSI E1.6-1-2012)

Verify the functionality of the emergency stop button on the chain motor control system. (ANSI E1.6-1-2012)

Review the maintenance records for each chain motor. Ensure regular inspections and maintenance are performed according to the manufacturer's recommendations. (ANSI E1.6-1-2012)

Verify that all shackles are rated for the intended load and are properly sized for the connecting hardware. (ASME B30.26)

Ensure that shackle pins are properly secured with cotter pins or other locking devices to prevent accidental dislodgement. (ASME B30.26)

Inspect wire rope slings for wear, kinks, corrosion, and broken wires. Remove any damaged slings from service. (OSHA 1926.251)

Verify that all slings are properly tagged with their load rating and identification information. (OSHA 1926.251)

Inspect turnbuckles for damage, corrosion, and proper thread engagement. Ensure they are locked to prevent loosening. (Best Practices)

Verify that eye bolts are properly installed and aligned with the direction of the load. Ensure they are fully seated and tightened. (ASME B30.26)

Inspect master links for deformation, cracks, and wear. Ensure they are properly sized for the connecting hardware. (ASME B30.9)

Ensure that all rigging hardware is compatible with each other and the suspended load. Avoid mixing different types of metals that could cause corrosion. (Best Practices)

Inspect soft goods (e.g., round slings, spansets) for cuts, abrasions, and chemical damage. Remove any damaged soft goods from service. (ASME B30.9)

Verify that rigging hardware is stored properly to prevent damage and corrosion. (Best Practices)

Verify that all flying elements (lighting fixtures, speakers, scenery) have independent safety cables installed and properly secured to a separate structural member. (ANSI E1.4-2019)

Ensure that safety cables are rated to support at least 10 times the weight of the suspended element. (ANSI E1.4-2019)

For critical elements, consider using a secondary suspension system in addition to the primary rigging. (Best Practices)

Inspect the attachment points on lighting fixtures and other suspended elements for damage and securement. (Manufacturer's Specifications)

Ensure that cables are properly managed and secured to prevent strain on connectors and tripping hazards. (Best Practices)

Verify the focus positions of lighting fixtures and ensure they are properly aimed and secured. (Best Practices)

Inspect speaker suspension systems for proper alignment and securement. Ensure that speakers are not overloaded. (Manufacturer's Specifications)

Verify that scenery elements are properly rigged and secured to prevent accidental movement or collapse. (Best Practices)

Test all motorized elements (e.g., moving lights, automated scenery) for proper operation and safety features. (ANSI E1.4-2019)

Verify adequate clearance between flying elements and other structures or personnel. (Best Practices)
