GEO D RIGGING PROCEDURE Page 17/935 GEO D RIGGING PROCEDUREBefore proceeding with assembly of GEO D arrays, please ensure that the components are present andundamaged. A component list is appended to this manual. In the event of any shortage, please contactyour 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 synchronisationand crosscheck between the operators are key elements for a reliable and safe set-up.5.1 SAFETY FIRSTGEO D / GEO SUB Rigging System structural computations and related documents are available inGeosoft2 or at Nexo (info@nexo.fr) 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 andcommon 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 thismanual to other rigging equipment such as motor hoists, steels, shackles etc. are made to clarify thedescription of GEO D / GEO SUB procedures. The user must ensure that operators are properly trainedby other agencies in the use of these items.The GEO D / GEO SUB Rigging System has been optimised for the deployment of curved verticaltangent arrays of GEO D / GEO SUB loudspeakers. Vertical angle adjustment between cabinets hasbeen 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 withextreme care. Only persons who are fully conversant with the operation of the GEO D / GEO SUBRigging System and provided with suitable safety equipment should deploy GEO Arrays. Misuse of theGEO 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 reliableservice in portable systems. Please take the time to read and understand this manual. Always useGEOSoft2 to determine the optimum angle settings for a particular venue, hang point and curvedvertical GEO D / GEO SUB. Applied forces and moments are strongly cabinet quantity and angleconfiguration dependent. Cluster configuration must be implemented and validated in Geosoft2 prior toinstallation.5.1.1 Flown Systems Safety• Always inspect all the rigging components and cabinets for damage before assembly. Payspecial attention to the lifting points, and safety clips. If you suspect that any of the componentsare damaged or defective, DO NOT USE THE AFFECTED PARTS. Contact your supplier forreplacements.• Read this manual carefully. Also be familiar with the manuals and safe working procedures forany 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 flyingequipment are understood and adhered to. Information on these regulations can usually beobtained from Local Government Offices.• When deploying a GEO D / GEO SUB system always wear protective headwear, footwear andeye protection.• Do not allow inexperienced persons to handle a GEO D / GEO SUB system. Installationpersonnel should be trained in loudspeaker flying techniques and should be fully conversant withthis manual.
