Rigging Manual 1.0
COSMO Line Array – Instructions for use
3 Intended Use
• Rigging and curving
Please read these instructions carefully before setting up and always keep them at hand
when working on or with the system!
Use
• Intended use
This rigging hardware consisting of the CRF-60 and CRF-80 rigging frames, C-PPA
pick-point adapter, CRF-PB pull-back frame, and C-STR tensioning strap is intended for
installing the HK Audio COSMO series and CF 118 subwoofer in a flown array, permanently
or temporarily, in compliance with the manufacturer's specifications.
The rigging frame may also serve to stack COSMO M/H units on the ground in compliance
with the manufacturer's specifications.
Any use other than specified is unintended. The manufacturer shall not be liable for
damages resulting from unintended use.
Note that the specifications for intended use require you to read and heed all of the
operating instructions and comply with inspection and maintenance requirements.
Heed all applicable local laws and regulations.
Use EASE Focus 3 software to model the configuration and loads prior to installation.
Never set up an array with more than ten C 8s unless you first conduct this software
analysis for a system larger than that.
Follow the rigging manual's instructions to assemble and disassemble the system. Ensure
connections are made properly by fully and completely inserting the quick-release pins,
with three attachment points per M/H unit and four for the CF 118.
In compressed mode, tighten the tensioning device (e.g. tensioning strap) between the
rigging frame and pull-back frame only to the extent necessary to achieve the desired
curvature. Do not exert excess force on the system's components when tightening the
tensioning device.
• Warranty and liability
HK Audio shall not be held responsible for damages due to improper use or failure to
comply with the safety specifications in the operating manual and rigging manual.
All warranty and liability claims for personal injury and property damages are excluded if
attributable to one or several of the following causes:
• failure to comply with operating manual instructions, voiding product liability and
warranty claims
• unintended use and misuse of rigging frames
• failure to comply with the instructions in the operating manual and rigging manual as to
the transport, storage, initial setup, installation, disassembly, operation, maintenance,
repair, inspection, and disposal of the system's components
• unauthorized structural modifications to parts of the system
• unauthorized modification of the parameters specified in the operating manual
• inadequate or improper repairs
Storage, maintenance, inspection and repair of rigging
hardware
• Storage and safekeeping when not in use
When the rigging hardware is not in use, store it in a safe place where it is protected
against exposure to potentially harmful elements.
• Maintenance
You are authorized to replace easily serviceable wearing or standard parts in accordance
with the manufacturer's instructions. Use original parts for this purpose. Tighten screws
and bolted connections whenever necessary.
• Cleaning
Use mild liquid soap or similar cleaning agents only to clean the rigging hardware. Protect
components against aggressive substances such as acids or strong alkalis.
• Repair
In the event that parts of the load-carrying equipment have been deformed, it is up to the
manufacturer to determine if they are repairable.
Solely the manufacturer is authorized to perform welding and repair jobs on load-carrying
equipment.
Technical specifi cation for COSMO rigging hardware
• Working load limits
CRF-60 rigging frame
350 kg
CRF-80 rigging frame
700 kg
C-PPA pick-point adapter
1000 kg
Static test coefficient: 2.5 (the ratio of applied proof-load to the working load limit)
Ambient operating temperature range: -10° to +60 °C
Wind speed limits: <8 B, gust speed <20 m/s
• Maximum number of flown M/H units
The maximum number of C 8s to be flown without using EASE Focus 3 simulation
software is ten. Heed the specifications of the EASE Focus 3 simulation software for all
other setups.
Be sure to add the weight of motors, cables and other hoisting gear when determining
flown loads.
• Modifications to COSMO rigging hardware
No structural modifications may be made without the manufacturer's consent. This also
applies to welding work performed on load-bearing parts. Structural alterations require
the manufacturer's written approval. Use original replacement and wearing parts only.
• Original HK Audio accessories
Use original HK Audio spare parts only. Using non-original aftermarket parts voids the
manufacturer's product liability. Parts are to be installed as stated in the rigging manual.
Store all documents pertaining to the system in a safe place.
