Rigging - Mackie HD 1801 Owner's Manual

Rigging

HD1801s may be individually flown 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
subwoofer 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 only suitable for
rigging via its fly points. NEVER attempt to
suspend the HD1801 by its handles.
Rigging Design Practices
Rigging a subwoofer requires determining:
1. The rigging methods and hardware that meet static,
shock, dynamic, and any other load requirements for
supporting the subwoofer 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 subwoofers 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 subwoofer. Some items, such as eyebolts, 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 subwoofer from structure.
Rigging Notes
The HD1801's integral mounting points are designed
to support only the weight of their own subwoofer,
or in combination with (1) one HD-Series full-range
loudspeaker, with suitable, external hardware. This
means that each HD subwoofer, alone or paired with an
HD-Series full-range loudspeaker, must be supported
independently of any other HD subwoofer and any other
loads.
A minimum of two rigging points must be used to hang
an HD1801. More may be used for creating the desired
hanging angle as shown in the illustrations on page 12.
All mounting points are fully load bearing so any two
may be used for rigging; no mounting points are
restricted to angle control only.
