RIGGING PROCEDURE
Before proceeding with assembly of GEO T 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 GEO T rigging system requires three experienced persons for set-up:
typically one motor hoist operator, and one GEO T operator per side of the array. Good synchronisation
and crosscheck between the operators are key elements for a reliable and safe set-up.
4.1 SAFETY FIRST
GeoT / CD18 Rigging System has been approved by Certification Organization RWTÜV. Structural
computations, test reports, certificates are available in NS-1 or at Nexo (
[email protected] ) upon request.
We include this section to remind you of safe practice when flying the GEOT / CD18 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 GEOT / CD18 loudspeaker systems. References in this manual to
other rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the description of
GEOT / CD18 procedures. The user must ensure that operators are properly trained by other agencies
in the use of these items.
The GEOT / CD18 Rigging System has been optimised for the deployment of curved vertical tangent
arrays of GEO T4805 / T2815 / CD18 loudspeakers. Vertical angle adjustment between cabinets has
been limited to specific settings to ensure correct acoustic coupling.
The GEOT / CD18 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 GEOT / CD18 Rigging
System and provided with suitable safety equipment should deploy GEO Arrays. Misuse of the GEOT /
CD18 Rigging System could lead to dangerous consequences.
Used and maintained correctly, the GEOT / CD18 Rigging System will give many years of reliable
service in portable systems. Please take the time to read and understand this manual. Always use NS-1
to determine the optimum angle settings for a particular venue, hang point and curved vertical GEOT /
CD18 array. Applied forces and moments are strongly cabinet quantity and angle configuration
dependent. Cluster configuration must be implemented and validated in NS-1 prior to installation.
4.1.1 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 GEOT / CD18 Rigging System.
• Applied forces and moments are strongly cabinet quantity and angle configuration dependent.
Cluster configuration must be implemented and validated in NS-1 prior to installation.
• 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 GEOT / CD18 system always wear protective headwear, footwear and eye
protection.
• Do not allow inexperienced persons to handle a GEOT / CD18 system. Installation personnel
should be trained in loudspeaker flying techniques and should be fully conversant with this
manual.
