Rigging Safety Regulations:
• 2006/42/EC
• EN ISO 12100-1: 2004
• EN1991-1 / EN1993-1-1 / EN1993-1-8 / EN1999-1-1
• DGUV Vorschrift 17/18
• ANSI E1.8-2018
General Rules for Suspension
• 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.
• Employ the services of a certified, professional rigger for hoisting, positioning, and attaching the equipment to the supporting
structure.
• 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.
• Consult local codes and regulations to fully understand the requirements for suspended loads in the venue in which equipment will
be suspended.
• Use only dedicated QSC LA108-AF and/or QSC LA112-AF array frames or the QSC LA-KIT-I installation kit for suspending a
loudspeaker array. Further details can be found below.
• Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can
have hidden structural weakness.
• Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate for suspending the
loads.
• Before lifting, 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. Discard any
worn, defective, or suspect parts and replace them with new, appropriately load-rated parts.
Shock Loading
When a load is moved or stopped, its static weight is magnified. Sudden movements can magnify the static weight several times. This is
called "shock loading."
The effects of shock loading can be instantaneous, or it can remain undetected. Proper preparation for shock loading requires careful
planning and knowledge of equipment, suspension, and lifting practices. Shock loading is most often the result of lifting and installation,
but natural forces (winds, earthquakes, etc.) can create shock loads several times the static load.
Shock loading poses a danger to equipment and workers. Because of this, structures and suspension equipment must be capable of
supporting several times the weight of the suspended equipment.
Flown Deployment with the LA-KIT-I
LA-KIT-I contains two (2) Shackle Adapters and one (1) M10 Pullback Eyebolt that allows users to deploy no more than three (3) LA112
or four (4) LA108 loudspeakers in an array configuration.
Attaching the Shackle Adapters to a Loudspeaker
1. Attach two Shackle Adapters to the Front Strikes on the left side of the loudspeaker.
Install one Shackle Adapter facing forward and one Shackle Adapter facing backward.
2. Attach two Shackle Adapters to the Front Strike on the right side of the loudspeaker.
Install one Shackle Adapter facing forward and one Shackle Adapter facing backward.
