1.5 ARE YOU NEW TO RIGGING?
If you are new to rigging, you should:
• Know the rules for safe rigging.
• Attend a safe rigging seminar.
• Meet and establish a relationship with a licensed mechanical or structural engineer. Get in the habit of asking them questions in-
stead of assuming their answers. Learn from what they tell you.
• Research and understand the codes, practices and requirements of the venues where you intend to operate your sound system.
1.6 INSPECTION AND MAINTENANCE
Suspension systems are comprised of mechanical devices and, as such, require regular inspection and routine maintenance to ensure
proper functionality. Before suspending or pole mounting any speaker system, always inspect all components (enclosure, suspension
frames or brackets, pins, eyebolts, etc.) for cracks, deformations, corrosion, or missing/loose/damaged parts that could reduce strength
and safety of the array. Do not suspend or pole mount a speaker until the proper corrective action has been taken.
Installed systems should be inspected at least once a year. The inspection must include a visual survey of all corners and load-bearing
surfaces for signs of cracking, water damage, delamination, or any other condition that may decrease the strength of the loudspeaker
enclosure.
Accessory suspension hardware provided with or for VTX systems must be inspected for fatigue at least once a year or as required by
local ordinance. The inspection must include a visual survey of the material for signs of corrosion, bending, or any other condition that
may decrease the strength of the fastener. Additionally, any eyebolts must be checked for possible spin-out of the enclosure.
Refer to the manufacturer’s guidelines for inspection and maintenance of all other hardware and fittings .

Prior to suspending the system, an expert, trained and experienced in suspending speaker systems, should inspect all parts and com-
ponents.
None of the information in this section should be used without first obtaining competent advice with respect to applicability to a given

Correct use of all included 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 suspended. Never exceed the maximum recom-
mended load ratings.
Before suspending any speaker system, always inspect all components (enclosure, rigging frames, pins, eyebolts, track fittings, etc.) for
cracks, deformations, corrosion, or missing/loose/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 JBL suspendable loud-
speaker models.
