Rigging - Mackie DRM212 Owner's Manual

Rigging

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
a DRM loudspeaker by its handle.
The fly points of the DRM212, DRM215 and DRM315
are shown on the previous page while examples
of a flown DRM315 are displayed below.
The DRM315 may be flown horizontally or
vertically, but the DRM212 and DRM215 may
only be flown vertically.
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 and required WLL (Working
Load Limit) for this support.
We strongly recommend 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 our loudspeakers will invariably require
hardware not supplied by us. 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.
We do offer certain accessory rigging items and some
of them 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 us to determine their
suitability or load rating for any particular application.
We are 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.
DRM loudspeakers may be individually
flown using a PA-A2 Eyebolt Kit, part
number 0028272.
Rigging Notes
The DRM loudspeaker's integral mounting
points are designed to support only the weight
of their own loudspeaker with suitable, external
hardware. This means that each DRM loudspeaker
must be supported independently of any other DRM
loudspeaker and any other loads. At least three rigging
points must be used to hang each DRM loudspeaker.
