Rigging Design Practices
Rigging a loudspeaker requires determining:
1. The rigging methods and hardware that meet static,
shock, dynamic, and any other load requirements for
supporting the loudspeaker from structure.
2. The design factor for and the required WLL (Work-
ing Load Limit) for this support.
Mackie strongly recommends the following rigging
practices:
1. Documentation: Thoroughly document the design
with detailed drawings and parts lists.
2. Analysis: Have a qualified professional, such as a
licensed Professional Engineer, review and approve the
design before its implementation.
3. Installation: Have a qualified professional rigger do
the installation and inspection.
4. Safety: Use adequate safety precautions and back-
up systems.
