Suspension 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. The Crown VRack 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 loudspeaker enclosure. Accessory suspension hardware provided
with or for the Crown VRack 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.
Crown is not responsible for the application of its products for any purpose or the misuse of this information for any purpose.
Furthermore, Crown 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
loudspeaker systems should inspect all suspension parts and components.
