Rigging
HD1221s may be individually flown horizontally or
vertically using M10 x 1.5 x 37 mm forged shoulder
eyebolts.
WARNING: Installation should only be done by
an experienced technician. Improper
installation may result in damage to the
equipment, injury or death. Make sure that the
loudspeaker is installed in a stable and secure way in
order to avoid any conditions that may be dangerous for
persons or structures.
WARNING: The cabinet is suitable for rigging
via its fly points. NEVER attempt to suspend
the HD1221 by its handles.
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
(Working 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.
Rigging Hardware and Accessories
Rigging Mackie loudspeakers will invariably require
hardware not supplied by Mackie. Various types of
load-rated hardware are available from a variety of
third-party sources. There are a number of such
companies specializing in manufacturing hardware for,
designing, and installing rigging systems. Each one of
these tasks is a discipline in its own right. Because of
the hazardous nature of rigging work and the potential
liability, engage companies that specialize in these
disciplines to do the work required.
Mackie does offer certain accessory rigging items,
primarily for attachment to the hardware integral with
the loudspeaker. Some items, such as eyebolts and
U-brackets, may be used with a variety of products.
While these accessories are intended to facilitate
installation, the wide variety of possible installation
conditions and array configurations do not permit
Mackie to determine their suitability or load rating for
any particular application.
Mackie is not in the business of providing complete
rigging systems, either as designers, manufacturers, or
installers. It is the responsibility of the installer to
provide a properly engineered, load-certified rigging
system for supporting the loudspeaker from structure.
Rigging Notes
The HD1221’s intergral mounting points are designed
to support only the weight of their own loudspeaker
with suitable, external hardware. This means that each
HD loudspeaker must be supported independently of
any other HD loudspeaker and any other loads.
A minimum of two rigging points must be used to hang
an HD1221. More may be used for creating the desired
hanging angle as shown in the illustrations on the
following page. All mounting points are fully load
bearing so any two may be used for rigging; no mounting
points are restricted to angle control only.
