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 DAS Audio are the user's
responsibility. Use at your own risk.
The DAS VANTEC-20A incorporates structures in
each side of the enclosure. Thess ironworks are
made of steel and aluminum and are fixed with
special screws in the wood side of the two systems.
On each one of these structures there is a steel rod
with a special axis screw which allows to stack or
rig the enclosures. The angles vary from 15º to 15º
with each VANTEC-20A. This system allows for easy
and safe rigging or stacking, with safety pins.
Flyable vantec series models feature internal
steel angles, so that flying points are available.
Eyebolt flying points are factory sealed with M10
screws, which are replaced with eyebolts on the
flying points as required. Flying with eyebolts is
very economical and safe, and is specially
recommended for installations where the boxes
are permanently fixed.
To perform any operations related to flying the
system, read the present document first, and act
on the warnings and advice given. The goal is to
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.
The working load limits in this manual are the
results of tests by independent laboratories. It is
the user's responsibility to stay within safe limits. It
is the user's responsibility to follow and comply
with safety factors, resistance values, periodical
supervisions and warnings given in this manual.
Product improvement by means of research and
development is on going at DAS. Specifications are
subject to change without notice.
It is common practice to apply 5:1 safety factors
for enclosures and static elements. For slings and
elements exposed to material fatigue due to
friction and load variation the following ratios
must be met; 5:1 for steel cable slings, 4:1 for steel
chain slings and 7:1 polyester slings. Thus, an
element with a breaking load limit of 1000 kg may
be statically loaded with 200 kg (5:1 safety factor)
and dynamically loaded with 142 kg (7:1 safety
factor).
When flying a system, the working load must
be lower than the resistance of each individual
flying point in the enclosure, as well as each box.
Hanging hardware should be regularly inspected
and suspect units replaced if in doubt. This is
important to avoid injury and absolutely no risks
should be taken in this respect. It is highly
recommended that you implement an inspection
and maintenance program on flying elements,
including reports to be filled out by the personnel
that will carry out the inspections. Local
regulations may exist that, in case of accident, may
require you to present evidence of inspection
reports and corrective actions after defects were
found.
