OVERHEAD RIGGING
Overhead rigging requires extensive experience, including amongst others, calculating working load
limits, installation material being used, and periodic safety inspection of all installation material and
the speaker. If you lack these qualifications, do not attempt the installation yourself. Improper
installation can result in bodily injury and property damage. Regardless of local installation
conditions, the following guidelines apply to all overhead rigging installations:
NEVER stand directly below the speaker(s) when rigging, removing or servicing.
To limit swinging or tipping the load when lifting the Imperio Sub speaker(s) and/or Imperio
speaker(s) into position when stacking, rigging, and/or suspending them using the available Imperio
Flybar(s), determine the center of gravity of the overall assembly, then rig or suspend the load
through a lifting point straight above the center of gravity. If using multiple rigging/anchor points and
a single lifting point, ensure that all suspension load angles used are symmetrical about the lifting
point with respect to the center of gravity so that load tensions are balanced between ropes, wires,
chains, or cables.
Structural members, such as a truss system, must always be used to attach or suspend loads from
a ceiling or to a wall. Never use a ceiling or wall surface itself to attach or suspend external loads,
the catastrophic failure of which can or likely will result in potential structural/property damage,
injury, or death.
Inspect/verify the structural integrity of the structural member used to suspend, hang, or support
external loads by looking for hidden structural weaknesses.
Avoid using threaded fasteners in wooden structural members for suspending overhead loads (nails,
screws, lag bolts, etc.). Threaded fasteners are inherently unreliable for suspending overhead loads,
due in part to possible hidden structural weaknesses in the wood (cracks, knots, etc.).
Suspension points provided by the installation owner or third-party may not be adequate to lift or
suspend the intended overhead loads.
You
must
consult an expert, such as a structural engineer or rigging specialist, if there is even the
slightest question or doubt about the structural integrity of any part of the installation.
Take all appropriate precautions and safety measures when placing equipment in potentially
dangerous locations, especially where public safety is a concern.
