Stands
•
Stands must only be installed on a plane area with a
maximum inclination angle of 5°.
•
When using stands or satellite systems under the
influence of horizontal forces, e.g. through wind, the
standing safety can be impaired. This is why
additional safety measures like attaching ballast
weights have to be taken.
•
If inclined tension cables or prolonged outriggers are
used, the area of danger has to be marked or even be
blocked.
•
Before lifting or lowering the telescopic tubes, you
must always block a safety area around the stand or
satellite system. This safety area must have a
diameter of 1.5 times the maximum height.
•
Lifted telescopic tubes always have to be secured
with a secondary securing!
•
The total weight of the installation (=total weight of all
individual parts) must never exceed the maximum
load of the installation area.
•
The stand has to be installed out of the reach of
people.
•
An unintended movement of the load has to be
avoided - also in case of fire!
•
The installer is responsible for adhering to the
carrying capacity given by the manufacturer, the
safety requirements and the qualification of possible
co-workers.
•
When people are located below the load, all
necessary safety measures have to be taken in order
to avoid injury.
•
The personnel have to be instructed on the content of
the user manual and on the dangers related with
operating stands.
•
Depending upon the individual installation spot, all
necessary measures against movement and for
securing the standing safety have to be created.
•
The installation is only allowed on carrying areas. In
some cases, an appropriate substructure, e.g. via a
balancing foot, has to be created. When choosing the
installation material, optimum dimensions have to be
chosen in order to secure maximum safety.
•
Speaker systems installed on stands or satellite
systems may cause severe injuries when crashing! If
installing on slippery surfaces, the legs must be
secured with screws or nails via the provided holes or
an anti-slippery mat has to be used.
Overhead installation
•
If this speaker system will be installed in a mounting
height higher than 1 meter (e.g. on the stage, on a
stage element or on a framework) we speak of
overhead installation. For overhead installation, the
speaker system must always be secured with an
appropriate secondary attachment. The speaker
system should be installed outside areas where
persons may walk by or be seated. The speaker
system has to be installed out of the reach of people.
•
Speaker systems in overhead installations may cause
severe injuries when crashing down! If you have
doubts concerning the safety of a possible installation,
do NOT install the speaker system!
•
The installation of the speaker system has to be built
and constructed in a way that it can hold 10 times the
weight for 1 hour without any harming deformation.
•
The installation must always be secured with a
secondary safety attachment, e.g. an appropriate
catch net. This secondary safety attachment must be
constructed in a way that no part of the installation
can fall down if the main attachment fails.
•
When rigging, derigging or servicing the speaker
system staying in the area below the installation
place, on bridges, under high working places and
other endangered areas is forbidden.
•
The operator has to make sure that:
- safety-relating and machine-technical installations
are approved by an expert before taking into
operation for the first time and after changes before
taking into operation another time.
- safety-relating and machine-technical installations
are approved by an expert after every four year in
the course of an acceptance test.
- safety-relating and machine-technical installations
are approved by a skilled person once a year.
•
Overhead rigging requires extensive experience,
including (but not limited to) calculating working load
limits, installation material being used, and periodic
safety inspection of all installation material and the
speaker system. If you lack these qualifications, do
not attempt the installation yourself, but instead use a
professional structural rigger. Improper installation
can result in bodily injury and or damage to property.
