14. Rigging Precautions: When mounting or suspending Mackie
loudspeaker enclosures, it is essential that load ratings, rigging
techniques, and special safety considerations be appropriate
for the installation. Use only the mounting/rigging points on
the loudspeaker enclosure intended for this purpose. The user
must determine the load requirements, dynamic loading, and any
other contributing factors affecting the loudspeaker installation.
The user must determine the proper safety factor for specific
applications and the required load rating of the connection
to structure. Comply with all applicable federal, state, and local
regulations.
Mackie strongly recommends the following rigging system practices:
Documentation: Thoroughly document the mounting/rigging design with
detailed drawings and parts lists.
Analysis: Have a licensed structural engineer or other qualifi ed profes-
sional review and approve the mounting/rigging design before its
implementation.
Installation: Use personnel experienced and qualifi ed for mounting/rigging
loudspeakers in accordance with and in compliance with all federal,
state and local regulations.
DANGER: Loudspeakers should be mounted or suspended only by persons
with knowledge of the proper hardware and rigging techniques. When
stacking or pole-mounting loudspeakers, be sure that they are stabilized
and secured from falling over or being accidentally pushed over. Failure to
follow these precautions may result in damage to the equipment, personal
injury, or death.
