Rigging with

AX-TRUSS

Introduction

Base of the support

AX-TRUSS

Hook clamp

The

rigging hardware has been

designed to fly the cabinets from structure trusses
of 50mm diameter (2 in diameter). The
base must be fixed to the upper rear corner of the
box by means of two M10 screws. The screw
needed to attach the

base to the upper

side of the box is the same that comes with the
box on that position. The screw to be inserted on
the rear side of the box is a special one that is
provided with the

accessory.

allows for several vertical angles from

+10º to -35º. The vertical angle is set up by
inserting a highly resistant quick release pin into
the holes in the

base.

AX-TRUSS

are the models in the

that feature the necessary hardware to be flown.
As has been said above,

are versatile

multipurpose cabinets which can also be used as
a low profile floor monitor.

cabinets feature 6 “L” shaped internal

metal hardware pieces, each one including 2 M10
nuts, thus providing a total of 12 rigging points.

the

elements

and

safety

precautions. 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 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.

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 ongoing at D.A.S. Specifications
are subject to change without notice.

To this date, there is no international standard

regarding the flying of acoustic systems. However,
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.
