Renkus-Heinz STXLA/9 - Manual (Page 16)

Line Array User’s Manual Line Array User’s Manual
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.
Do not fly the system over areas to which the audience has access.
Ensure that the system is secure and prevented from pivoting about the motor hoist. Avoid any form of dynamic
loading to the assembly.
NEVER attach any item to the RHANG hardware other than the RHANG accessories.
When flying outdoor systems ensure that the system is not exposed to wind or snow loads and is protected
from rainfall.
The RHANG flying hardware requires regular inspection. We recommend that the system be inspected visually
at every opportunity. For more information on visual inspection procedures and common problems with rigging
components, download the Rigging Inspection Poster from ATM Flyware (http://www.atmflyware.com/
flyhome.html).
When de-rigging the system ensure that the same care is given to the procedure as for the installation. Pack
RHANG components carefully to prevent damage during transit.
Ground Stacking Loudspeakers Safely
Statistically, many more injuries occur due to unstable ground stacked PA systems than to improperly 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 forward due to
vibration. This may require attaching wood 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 6 feet 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 Renkus-Heinz distributor 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.Training & Education
Correct training is fundamental to safe practice when working with loudspeaker flying systems. We recommend
that users contact local industry associations for information on appropriate courses.
Rigging Procedures
The designs of the RHANG/LA and RHANGSTLA rigging systems have been optimized for the mechanical and
acoustical characteristics of Renkus-Heinz line array modules. RHANG flying hardware enables a variety of system
configurations to be flown with a minimum number of motor hoists. Vertical angle adjustment between cabinets
has been limited to specific settings to ensure proper acoustic coupling.
Before flying any Renkus-Heinz line array, please ensure that all necessary components are present and
undamaged.
The RHANG system is a professional precision tool and should be handled with extreme care. Only persons
who are fully conversant with the operation of the RHANG flying hardware and provided with suitable safety
equipment should install and operate the system. Misuse of the RHANG hardware system could lead to injury.
Please refer to the Safety section below for advice concerning installation and handling.
Maximum efficiency will be realized when three experienced persons participate in the set-up: typically one
motor hoist operator, and one PN/LA or STLA operator per side of the array. Good synchronization and
crosscheck between the operators are the keys to reliability and safety.
Used and maintained correctly, RHANG flying hardware will give many years of reliable service in portable
systems. This requires frequent, regular and thorough inspection, maintenance and cleaning of the system. Please
refer to the appendix for further information.
SAFETY FIRST
This manual offers guidance only for Renkus-Heinz loudspeaker systems. References in this manual to other
rigging equipment, such as motor hoists, steels, shackles etc. , are made to clarify the description of rigging
procedures. The user must ensure that operators are properly trained by other agencies in the use of these
items.
The following points are designed to remind the user of safe practice when flying any loudspeaker system. They cannot
address every possible circumstance in which the system might be deployed; therefore the user must always apply his
or her knowledge, experience and common sense. If in any doubt, seek assistance from qualified rigging personnel.
Flying Loudspeakers Safely
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.
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 flying a loudspeaker system always wear protective headwear, footwear and eye protection.
Do not allow inexperienced persons to handle the loudspeaker 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.
