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.
Secondary Attachment
The speaker system must always be secured via appropriate eye bolts and
appropriate safety bonds.
The eyelets must always hold at least 12 times the weight of the speaker systems.
For overhead use, always install a safety bond. You must only use safety bonds
complying with DIN 56927, quick links complying with DIN 56926, shackles
complying with DIN EN 1677-1 and BGV C1 carbines. The safety bonds, quick links,
shackles and the carbines must be sufficiently dimensioned and used correctly in
accordance with the latest industrial safety regulations (e. g. BGV C1, BGI 810-3).
Please note:
Before installing the eye bolts, make sure that the thread is always in perfect condition and free
from dirt etc.
Install the eye bolts in the threaded holes of the speaker system. The eye bolts must be tightened until stop
position, hand-tight and without any tools.
Insert the quick links of the safety bonds in the eye bolts of the speaker system. Pull the safety bonds over a
safe fixation spot. Insert the end in the quick link and tighten the safety screw.
The maximum drop distance must never exceed 20 cm. A safety rope which already hold the strain of a
crash or which is defective must not be used again.
Please note:
For overhead rigging in public or industrial areas, a series of safety instructions have to be
followed that this manual can only give in part. The operator must therefore inform himself on the current
safety instructions and consider them.
The manufacturer cannot be made liable for damages caused by incorrect installations or insufficient safety
precautions!
