RIGGING
The goal is to the allow the user to become
familiar with the mechanical elements required to
fly the acoustic system, as well as the safety
measures to be taken during set-up and teardown.
Only
experienced installers with adequate
knowledge of the equipment and local safety
regulations should fly speaker boxes. It is the
user's responsibility to ensure that the systems to
be flown (including flying accessories) comply with
state and local regulations.
Absolutely no risks should be taken with
regards to public safety. When flying enclosures
from
ceiling support structures, extreme care
should be taken to assure the load bearing
capabilities of the structures so that the installation
is absolutely safe. Do not fly enclosures from
unsafe structures. Consult a certified professional if
needed. All flying accessories that are not supplied
by D.A.S. Audio are the user's responsibility. Use
at your own risk.
To access the two rigging points on the top
side of the enclosure, remove the rubber caps and
the allen-head screw beneath it. Also remove the
allen-head screw on the backside of the enclosure
to free a rigging point. Fix a M10 eyebolt in each
point. Note that each rigging point has 200 kg
(440 lb) working load limit. Then choose the slings
or chains of required load resistance and length,
bearing in mind that the length difference between
the front and back slings or chains will determine
the vertical orientation. Alternatively, the back
bottom eyebolt points can be used to provide
vertical orientation.
The set is an optional set of three M10
eyebolts and three carabiners.
Each eyebolt has a rated working load
of 200 kg. (440 lb). Each carabiner has a
working load of 330 kg (726 lb). If using other
hardware, make sure it is rated to handle the
required load.
When using eyebolts it is important to bear in
mind that the rated working load is only true for a
load applied in the plane of the eye, and is
significantly reduced for other angles. The drawing
illustrates the concept. The table shows the
variation of the working load as a function of the
load angle. In the case of the
eyebolt, this
means that the 200 kg working load becomes 60
kg at 45 degrees. Do not use eyebolt flying if the
load angle is higher than 45 degrees.
