Before proceeding with assembly of RS18 arrays, please ensure that the components are present and
undamaged. A component list is appended to this manual. In the event of any shortage, please contact
your supplier.
For maximum efficiency the RS18 rigging system requires three experienced persons for set-up:
typically one motor hoist operator, and one RS18 operator per side of the array. Good synchronisation
and crosscheck between the operators are key elements for a reliable and safe set-up.
5.1 SAFETY FIRST
RS18 Rigging System structural computations and related documents are available in Geosoft2 or at
Nexo ([email protected]) upon request.
We include this section to remind you of safe practice when flying the RS18 system. Please read it
carefully. However, user must always apply his or her knowledge, experience and common sense. If in
any doubt, seek advice from your supplier or NEXO agent.
This manual offers guidance only for RS18 RAYSUB systems. References in this manual to other
rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the description of
RS18 procedures. The user must ensure that operators are properly trained by other agencies in the
use of these items.
The RS18 Rigging System has been optimised for the deployment of vertical arrays of RS18
loudspeakers. No angle adjustment is allowed between cabinets.
The RS18 Rigging System is a professional precision tool set, and should be handled with extreme
care. Only persons who are fully conversant with the operation of the RS18 Rigging System and
provided with suitable safety equipment should deploy RAYSUB Arrays. Misuse of the RS18 Rigging
System could lead to dangerous consequences.
Used and maintained correctly, the RS18 Rigging System will give many years of reliable service in
portable systems. Please take the time to read and understand this manual.
5.1.1 Flown Systems Safety
• Always inspect all the rigging components and cabinets for damage before assembly. Pay special
attention to the lifting points, and safety clips. If you suspect that any of the components are damaged
or defective, DO NOT USE THE AFFECTED PARTS. Contact your supplier for replacements.
• Read this manual carefully. Also be familiar with the manuals and safe working procedures for any
ancillary equipment that will be used with the RS18 Rigging System.
• Ensure that all local and National regulations regarding the safety and operation of flying equipment
are understood and adhered to. Information on these regulations can usually be obtained from Local
Government Offices.
• When deploying a RS18 system always wear protective headwear, footwear and eye protection.
• Do not allow inexperienced persons to handle a RS18 system. Installation personnel should be
trained in loudspeaker flying techniques and should be fully conversant with this manual.
• Ensure that motor hoists, hoist control systems and ancillary rigging components are currently
certified as safe and that they pass a visual inspection prior to use.
• Ensure that the public and personnel are not allowed to pass beneath the system during the
installation process. The work area should be isolated from public access.
• Never leave the system unattended during the installation process.
• Do not place any object, no matter how small or light, on top of the system during the installation
procedure. The object may fall when the system is flown and is likely to cause injury.
• Secondary safety steels must be installed once the system has been flown to the operating height.
Secondary steels must be fitted irrespective of requirements of the local safety standards applicable
to the territory.
