Routine Inspections
Thoroughly inspect all rigging hardware
and components used to support the
loudspeaker. Do this on a regular periodic
basis, whether components are integral with
or external to the loudspeaker or whether
factory or user-supplied. The interval between
inspections and scope of the inspections will
depend on the installation and the conditions
of use. The rigging inspection interval must
not exceed 1 year.
Look for loose fasteners, cracked or corroded
fittings, frayed wirers and signs of strain or
ware on anything that could detach from the
speaker box or associated fittings.
If there is any question about the integrity
or capability of any installation component
to perform its intended function when
used to suspend or mount a loudspeaker,
immediately remove it from service for repair
or replacement.
Do not under any circumstances use a
loudspeaker’s handles to support the
weight of the loudspeaker except for their
intended use: hand carrying. The handles
are not rated to support the load of the
loudspeaker for temporary or permanent
installation.
Note: If you are not sure of the safety of
your loudspeaker rigging, consult a licensed,
qualified professional engineer or professional
rigger. All rigging work must be done in
accordance with and in compliance with all
applicable regulations governing such work.
The Basics Of Safe Rigging
Rigging a loudspeaker array requires
determining accurately:
The rigging methods and hardware 1.
that meet static, dynamic, and
any other load requirements for
supporting the loudspeaker from the
intended structure.
The design limitations and capacities 2.
for and the required WLL (Working
Load Limit) for this support.
The Design Factor for all working load limits is
a minimum of 8:1. In other words, the rigging
for a 100 KG speaker must be able to carry
800Kg.
