4. Rigging Inspection and Precautions

Electro-Voice X-Line 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 track and bracket assemblies on the enclosures for any cracks, deformations, 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 X-Line systems.

Electro-VoiceX-Line Rear Rigging Hinges: Prior to each use, inspect the rigging hinges for cracks, burrs, corrosion or missing or damaged components that could reduce hinge assembly strength. Replace any rigging hinges that are damaged or missing hardware. Always double check that each rigging hinge is securely locked into position in the track on the X-Line enclosures and grids before lifting. Never exceed the limitations or maximum recommended load for the X-Line hinges.

Electro-VoiceX-Line Front Chain Rigging-Strap Assemblies: Prior to each use, inspect the chain for cracks, burrs or corrosion that could reduce rigging strap strength. Inspect the rigging fittings for any cracks, burrs, deformation, corrosion or missing or damaged components that could reduce fitting strength. Replace any rigging straps that have damaged chain, or damaged or missing hardware. Always double check that each fitting on each of the rigging straps is securely locked into position in the track on the X-Line enclosures and grids before lifting. Never exceed the limitations or maximum recommended load for the rigging strap assemblies.

Electro-VoiceX-LinePull-Up Bars: Prior to each use, inspect the pull-up bar assembly for cracks, burrs, corrosion or missing or damaged components that could reduce hinge assembly strength. Replace any rigging hinges that are damaged or missing hardware. Always double check that each rigging hinge is securely locked into position in the track on the X-Line enclosures and grids before lifting. Never exceed the limitations or maximum recommended load for the X-Line pull-up bars.

Grid Assemblies: Prior to each use, inspect the grid assembly and associated hardware for any cracks, deformations, broken welds, corrosion, missing or damaged components that could reduce the grid assembly strength. Replace any damaged grid assemblies. Never exceed the limitations or maximum recommended load intended for grid assembly design. Never exceed the limitations or maximum recommended load for the grid assemblies.

Chain Hoists: Prior to each use, inspect the chain hoist and associated hardware (including motor, if applicable) for any cracks, deformation. Broken welds, corrosion, missing or damaged components that could reduce the hoist strength. Replace any damaged chain hoists. Never exceed the limitations or maximum recommended load specified by the hoist manufacturer. Always follow manufacturers’ recommendations for operation, inspection, and certification. Always raise and lower the load slowly and evenly, avoiding any rapid changes in speed or shifting loads that could result in a sudden jolt to the suspended system.
