FLYING AND SUSPENSION
JBL SRX700 series offers 4 models with suspendable capabilities: SRX715F, SRX722F, SRX725F and
SRX738F. Before attempting to suspend your speakers, read and understand the following safety information.
IMPORTANT SAFETY WARNING!
The information in this section has been assembled from recognized engineering data and is intended for infor-
mational purposes only. None of the information in this section should be used without first obtaining competent
advice with respect to applicability to a given circumstance. None of the information presented herein is intended
as a representation or warranty on the part of JBL. Anyone making use of this information assumes all liability
arising from such use.
All information presented herein is based upon materials and practices common to North America and may not
directly apply to other countries because of differing material dimensions, specifications, and/or local regulations.
Users in other countries should consult with appropriate engineering and regulatory authorities for specific
guidelines.
Correct use of all rigging hardware is required for secure system suspension. Careful calculations should always
be performed to ensure that all components are used within their working load limits before the array is suspend-
ed. Never exceed the maximum recommended load ratings.
Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, eye-
bolts, track fittings, etc.) for cracks, deformations, corrosion, missing, loose or damaged parts that could reduce
strength and safety of the array. Do not suspend the speaker until the proper corrective action has been taken.
Use only load-rated hardware when suspending SRX700 suspendable versions.
Are You New to Rigging?
If you are new to rigging, you should do the following:
;
Read and study JBL Technical Note Volume 1, Number 14: Basic Principles for Suspending
Loudspeaker Systems (available at http://www.jblpro.com/pub/technote/tn_v1n14.pdf).
;
Know the rules for safe rigging.
;
Attend a safe rigging seminar, such as that presented by professionals like Rigging Seminars™ or by
Chain Motor Hoist manufacturers like Columbus McKinnon Corp. (manufacturers of the C/M Lodestar).
;
Meet and establish a relationship with a licensed mechanical or structural engineer. Get in the habit of
asking them questions instead of guessing about their answers. Learn from what they tell you.
;
Meet and discuss this aspect of your business with your Insurance Agent.
;
Research and understand the codes, practices, and requirements in the venues where you intend to
operate your sound system.
General Hardware Information
Any hardware used in an overhead suspension application must be load rated for the intended use. Generally,
this type of hardware is available from rigging supply houses; industrial supply catalogs and specialized rigging
distributors. Local hardware stores do not usually stock these products. Hardware that is intended for overhead
suspension will comply with ASME B30.20 and will be manufactured under product traceability controls.
Compliant hardware will be referenced with a working load limit (WLL) and a traceability code.
Attachment to Structures
A licensed Professional Engineer must approve the placement and method of attachment to the structure prior to
the installation of any overhead object. The following performance standards should be provided to the
Professional Engineer for design purposes; Uniform Building Code as applicable, Municipal Building Code as
applicable, and Seismic Code as applicable.
The installation of the hardware and method of attachment must be carried out in the manner specified by the
Professional Engineer. Improper installation may result in damage, injury or death.
