Page 20/62 GEO M6 HARDWARE SETUP PROCEDURE
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 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.
Ensure that the system is secure and prevented from pivoting around the motor hoist.
Avoid any form of excessive dynamic loading to the assembly (structural computations on GEO M6
Rigging System are based on a 1/1.2 factor for hoist or motor acceleration).
NEVER attach any item to the GEO M6 system other than the GEO M6 accessories.
When flying outdoor systems, ensure that the system is not exposed to excessive wind or snow loads
and is protected from rainfall.
If wind velocity reaches or exceeds Beaufort 7 (60 km/h – 38 mp/h), the system must be landed.
The GEO M6 Rigging System requires regular inspection and testing by a competent test centre. NEXO
recommend that the system is load tested and certified annually or more frequently if local regulations
require.
When de-rigging the system ensure that the same duty of care is given to the procedure as for the
installation. Pack GEO M6 components carefully to prevent damage in transit.
Ground Stacking Safety 8.1.2
Statistically, many more injuries occur due to unstable ground stacked PA systems than those
associated with flown systems. There are several reasons for this fact, however the message is clear:
Always survey the supporting structure upon which a ground stack is to be built. Always look beneath
PA wings to inspect the deck support and if necessary ask for the stage scrims and dressings be
removed to allow access.
If the stage surface slopes, as it does in some theatres, ensure that the system is prevented from sliding
forwards due to vibration. This may require the fitting of timber battens to the stage floor.
For outdoor systems ensure that that the system is protected from wind forces which might cause the
ground stack to become unstable. Wind forces can be huge, especially upon large systems, and should
never be underestimated. Observe meteorological forecasts, calculate the “worst case” effect upon the
system prior to erection and ensure that the system is secured appropriately.
Take care when stacking cabinets. Always employ safe lifting procedures and never attempt to build
stacks without sufficient personnel and equipment.
Never allow anyone, whether operators, artists or members of the public to climb onto a ground stacked
PA system. Anyone who needs to climb over 2m (6 ft) high should be fitted with suitable safely
equipment including a clip-on harness. Please refer to local Health and Safety legislation in your
territory. Your dealer can help with advice on access to this information.
Apply the same attention to all safety matters when de-stacking systems.
Be aware that safety procedures are as important in the truck and in the warehouse as they are at the
venue.
