Quickfly Operating Manual - Meyer Sound Laboratories Inc.

CARE, USE, AND INSPECTION OF CONNECTORS
The physical integrity of Meyer Sound's QuickFly system
depends on proper inspection, maintenance, and use. For
additional information, refer to ANSI B30.9, OSHA
1910.184, or appropriate documents from your local regulatory
body.
Care
Connectors and chains used in the QuickFly system require
careful storage and regular maintenance.
· Store in a clean, dry place.
· To avoid corrosion, oil before prolonged storage.
· Do not heat the connectors; this will alter the thermal
treatment.
· Do not plate or change surface finish.
Use
To protect both operators and system components, observe
these precautions :
· Before use, inspect the chain and all attachments following
the instructions detailed in Inspection.
· Do not exceed the working load limit. Any of the factors
listed here can reduce the working load:
· Acceleration in rate of lifting arrays can produce
dangerous overloading.
· Variation in the angle of the load: as the angle
decreases, the working load presented to the connector
will increase.
· Twisting , knotting , or kinking subjects connector

links to unusual loading and decreases the effective
working load.
· Use for purposes other than those for which the
product is intended can reduce the effective working
load.
· Free the chain of all twists, knots, and kinks.
· Center load in the hook(s); hook latches must not support
the load.
· Avoid sudden jerks when lifting and lowering
· Balance all loads; avoid tipping of loads.
· Use pads around sharp corners.
· Do not drop loudspeakers on chains or connectors.
Inspection
Inspect connectors and chain links regularly and keep a
record of all chain inspections.
· Before inspecting, clean with a non-acid/non-caustic
solvent so that marks, nicks, wear, and other defects are
visible.
· Inspect each link and connector part for:
· Twists or bends.
· Nicks or gouges.
· Excessive wear at bearing points.
· Stretch.
· Distorted or damaged master links, coupling links
or attachments, especially spread in the throat
openings of hooks.
· Use paint to plainly mark each link or attachment showing
any conditions listed here to indicate rejection;
remove from service until properly repaired.
