Rigging inspection and precautions
Loudspeaker systems: Prior to each use, inspect the enclosures for any cracks, deformations
or missing or damaged components that could reduce enclosure strength. Inspect the rigging
pins, hinge bars, linking bars and rigging channel bars for cracks, corrosion or other
deformations that could reduce their strength and integrity. Hardware that is bent or showing
signs of more than cosmetic surface corrosion should be replaced immediately.
Grids: Prior to each use, inspect the grid side arms, spreader bars, linking bars, and rigging
pins for any cracks, corrosion, missing or damaged parts or any other deformation that could
reduce their strength and integrity.
Verify there are no missing rigging pins and all lanyards are securely attached. Hardware that
is bent or showing signs of more than cosmetic surface corrosion should be replaced
immediately.
Lifting hoists: Prior to each use, inspect the lifting hoist(s) and associated hardware
(including motor(s), if applicable) for any cracks, deformation, broken welds, corrosion,
missing or damaged components that could reduce the hoist strength. Replace any damaged
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 or the
structure from which it is suspended.
Building, tower or scaffold supports: Prior to each use, the strength and load-bearing
capabilities of the building, tower or scaffold structural supports should be evaluated and
certified by a professional engineer as being adequate for supporting the intended rigging
system (including the loudspeakers, grids, chain hoists, and all associated hardware). Prior to
each use, inspect the building, tower or scaffold structural supports for any cracks,
deformation, broken welds, corrosion, missing or damaged components that could reduce the
structural strength. Damaged structural supports should be replaced or repaired and
recertified by a professional engineer. Never exceed the limitations or maximum
recommended load for the supports.
Miscellaneous mechanical components: Prior to each use, inspect all mechanical components
(chain, wire ropes, slings, shackles, hooks, fittings, ratchet straps, etc.) for any cracks,
deformation, broken welds, slipping crimps, fraying, abrasion, knots, corrosion, chemical
damage, loose screws, missing or damaged components that could reduce the maximum
strength specified by the component manufacturer. Replace any damaged mechanical
components immediately. Never exceed the limitations or maximum recommended load for
the mechanical components.
