IMPORTANT RIGGING SAFETY WARNING!
The information in this section has been assembled from recognized engineering data and is intended for informational 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
Danley Sound Labs. 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 hardware is required for secure system suspension. Careful calculations should always be performed to ensure
that all components are used within their rated workload before the array is suspended. Never exceed maximum recommended
load ratings.
Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, 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 Danley subwoofers.
Are You New to Rigging?
If you are new to rigging, you should do the following:
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 requi
rements in the venues where you intend to operate your sound system
.
General Hardware Information
All Danley subwoofers which are intended to be flown are provided with
⅜
inch - #16 hardware. Any hardware used in an
overhead suspension application must be load rated for the intended use. Generally, this type of hardware is available only from
rigging supply houses; industrial supply catalogs and specialized rigging distributors. Local hardware stores do not usually stock
these products.
Attachment to Structures
A licensed Professional Engineer must approve placement and method of attachment to structures prior to 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, Seismic Code as applicable. Installation of
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.
Rigging Hardware Inspection & Maintenance
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and routine maintenance
to insure proper function ability. Danley subwoofers must be inspected for fatigue at least annually. The inspection shall include
a visual survey of all corners and load bearing surfaces for signs of cracking, water damage, de-lamination, or any other condition
that may decrease the strength of the subwoofer enclosure. Accessory rigging hardware provided with or for Danley subwoofers
must be inspected for fatigue at least annually. The inspection shall include a visual material survey for signs of corrosion, bending
or any other condition that may decrease strength of
the fastener. For other fittings used, refer to the manufacturer’s inspection
and maintenance guidelines for process.
Danley Sound Labs is not responsible for the application of its products for any purpose or the misuse of this information for any
purpose. Furthermore, Danley Sound Labs is not responsible for the abuse of its products caused by avoiding compliance with
inspection and maintenance procedures or any other abuse. Prior to suspending the system, an expert, trained and experienced
in flying subwoofer systems should inspect all rigging parts and components.
