Rigging Manual
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. Never exceed
the limitations or maximum recommended load for the mechanical components.
