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-Voice X-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-Voice X-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-Voice X-Line Pull-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.
