4. Rigging Inspection and Precautions

Electro-Voice XLC Loudspeaker Systems:

Prior to each use, inspect the loudspeaker enclosures for any cracks, deformations, missing or damaged components that could reduce enclosure strength. Inspect the rigging frame assemblies on the enclosures for any cracks, deformations, corrosion, missing or loose screws which could reduce the flying hardware strength. Replace any loudspeaker systems that are damaged or missing hardware. Never exceed the limitations or maximum recommended load for the XLC systems.

Electro-Voice XLC Front Rigging Button Bar Assemblies: Prior to each use, inspect the front rigging button bars and the front rigging tubes for any cracks, burrs, deformations, corrosion or missing or damaged components that could reduce button bar assembly strength. Always check to make sure that the button bar can move freely in the front rigging tube and that the spring- loaded buttons can move freely and easily lock into the rigging tube holes. Replace any button bars that are damaged or missing hardware. Always double check that each button on each button bar is securely locked into position in the front rigging tubes on the XLC enclosures and grids before lifting. Never exceed the limitations or maximum recommended load for the XLC rigging hardware.

Electro-Voice XLC Rear Swing Arm Assemblies: Prior to each use, inspect the rear rigging swing arms, the rear rigging slots and rear rigging holes for any cracks, burrs, deformations, corrosion or missing or damaged components that could reduce button bar assembly strength. Always check to make sure that the swing arm bar can move freely in the rear rigging slots and that the quick-release locking pins can be easily inserted in the swing arm slot and rigging holes to lock the arm Replace any swing arms that are damaged or missing hardware. Always double check that each swing arm is securely locked in the rear rigging holes with a quick-release pin. Never exceed the limitations or maximum recommended load for the XLC rigging hardware.

Electro-VoiceQuick-Release Pins: Prior to each use, inspect the quick-release pins on the rigging frame assemblies any for cracks, burrs, deformations, corrosion or missing or damaged components that could reduce the pin strength. Replace any quick-release pins that are damaged. Always double check that quick-release pin is securely locked to the swing arm and rear frame assemblies on the XLC enclosures before lifting. Never exceed the limitations or maximum recommended load for the XLC rigging hardware.

Pick-Up Grid Assemblies: Prior to each use, inspect the pick-up grid bar assembly any for cracks, burrs, deformations, corrosion or missing or damaged components that could reduce the pick-up assembly strength. Replace any pick-up grids that are damaged or missing hardware. Always double check that each pick-up grid is securely locked to the front button bar assemblies and the rear swing arm assemblies on the XLC enclosures before lifting. Never exceed the limitations or maximum recommended load for the pick-up grids.
