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.
