The operator has to make sure that safety-relating and machine-technical installations are approved by an
expert after every four year in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are approved by a
skilled person once a year.
IMPORTANT! 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.
The speaker system has to be installed out of the reach of people.
Caution: 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!
Before rigging make sure that the installation area can hold a minimum point load of 10 times the speaker
system's weight.
DANGER TO LIFE!
Before taking into operation for the first time, the installation has to be approved by an expert!
Rules for suspension
•
Correct use of all suspension hardware and components is imperative in sound system suspension and
deployment.
•
Always calculate suspended loads before lifting to ensure suspension components and hardware are used
within their respective load limits.
•
Research local codes and regulations to fully understand the requirements for suspended loads in the
venue in which the equipment is to be suspended.
•
Use only shackle holes for suspension of array (outer frame).
•
Be absolutely certain of the integrity of any structural member intended to support suspended loads.
Hidden structural members can have hidden structural weakness.
•
Consult a professional mechanical or structural engineer licensed in the jurisdiction of the sound system
installation to review, verify, and approve all attachments to the building or structure.
•
Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate
for the loads to be suspended.
•
Employ the services of a professional rigger for hoisting, positioning, and attaching the equipment to the
supporting structure.
•
Always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings,
shackles, etc.) for cracks, wear, deformation, corrosion, missing, loose, or damaged parts that could reduce
the strength of the assembly before lifting. Discard any worn, defective, or suspect parts and replace them
with new appropriately load-rated parts.
Shock loading
When a load is either moved or stopped, its static weight is magnified. Sudden movements can magnify the
static weight several times. This magnification of static weight is termed "shock loading". Shock loading
poses a danger to equipment and workers. The effects of shock loading can be instantaneous, or they may
remain undetected unless the equipment is visually damaged. Avoiding shock loading requires careful
planning and knowledge of equipment, suspension, and lifting practices.
Shock loading of equipment and structures is usually confined to lifting and installation, but natural forces
(winds, earthquakes) can impose shock loads several times the static load. This is why structures and
suspension equipment must be capable of supporting several times the weight of the equipment suspended.
