RIGGING PROCEDURE
Before proceeding with assembly of GEO D 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 D rigging system requires three experienced persons for set-up:
typically one motor hoist operator, and one GEO D 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
GEO D / GEO SUB 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 GEO D / GEO SUB 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 GEO D / GEO SUB loudspeaker systems. References in this
manual to other rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the
description of GEO D / GEO SUB procedures. The user must ensure that operators are properly trained
by other agencies in the use of these items.
The GEO D / GEO SUB Rigging System has been optimised for the deployment of curved vertical
tangent arrays of GEO D / GEO SUB loudspeakers. Vertical angle adjustment between cabinets has
been limited to specific settings to ensure correct acoustic coupling.
The GEO D / GEO SUB 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 GEO D / GEO SUB
Rigging System and provided with suitable safety equipment should deploy GEO Arrays. Misuse of the
GEO D / GEO SUB Rigging System could lead to dangerous consequences.
Used and maintained correctly, the GEO D / GEO SUB Rigging System will give many years of reliable
service in portable systems. Please take the time to read and understand this manual. Always use
GEOSoft2 to determine the optimum angle settings for a particular venue, hang point and curved
vertical GEO D / GEO SUB. Applied forces and moments are strongly cabinet quantity and angle
configuration dependent. Cluster configuration must be implemented and validated in Geosoft2 prior to
installation.
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 GEO D / GEO SUB Rigging System.
• Applied forces and moments are strongly cabinet quantity and angle configuration dependent.
Cluster configuration must be implemented and validated in Geosoft2 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 GEO D / GEO SUB system always wear protective headwear, footwear and
eye protection.
• Do not allow inexperienced persons to handle a GEO D / GEO SUB system. Installation
personnel should be trained in loudspeaker flying techniques and should be fully conversant with
this manual.
