SAFETY RESPONSIBILITIES “ABOVE THE HOOK”
In most touring applications of rigging systems, the touring sound provider is normally responsible for ensuring the safety of
the suspension system only below the attachment point. The safety and suitability of the attachment point is generally seen
as the responsibility of the venue owner or operator. However, this distinction (“above the hook” versus “below the hook”)
can be open to interpretation. Touring system operators should double-check to make certain that attachment points are
approved and suitably load rated, and that the points used are those identified as such by the venue owner or operator. AS
AN EXTRA PRECAUTION, CAREFUL INSPECTION OF THE ATTACHMENT POINTS IS ADVISED BEFORE FLYING, PARTICU

LARLY IN OLDER VENUES OR THOSE HOSTING FREQUENT EVENTS USING LARGE SOUND AND LIGHTING SYSTEMS.
In any case, Meyer Sound QuickFly systems are intended only for suspension from approved rigging points, each known to
have ample SWL margins for the system components suspended below them.
INSPECTION AND MAINTENANCE
The Meyer Sound QuickFly systems are an assembly of mechanical devices, and are therefore subject to wear and tear over
prolonged use, as well as damage from corrosive agents, extreme impact, or inappropriate use.
BECAUSE OF THE SAFETY ISSUES INVOLVED, USERS MUST ADOPT AND ADHERE TO A SCHEDULE OF REGULAR IN
-
SPECTION AND MAINTENANCE. IN TOURING APPLICATIONS, KEY COMPONENTS MUST BE INSPECTED BEFORE EACH
USE.
Such inspection includes examination of all load-bearing components for any sign of undue wear, twisting, buckling,
cracking, rusting, or other corrosion. In regard to rust and corrosion, the main components of a QuickFly system are either
protected by an exterior coating or made from stainless steel, which is impervious to rust and resistant to most corrosive
fluids. Nevertheless, normal use and shipping vibrations can wear through the protective coatings, and extremely corrosive
fluids (such as battery acid) can cause severe damage with prolonged exposure even to protected parts. Particular atten-
tion should be given to screws, bolts, and other fasteners to make certain the fittings are tight and secure. Metal seams and
welds should be examined for any sign of separation or deformation. Meyer Sound strongly recommends that written docu-
mentation be maintained on each QuickFly system, noting date of inspection, name of inspector, points of system checked,
and any anomalies discovered.
Annual Comprehensive Examination and Test Program
In addition to routine checks on the road for touring systems, Meyer Sound also recommends a careful, comprehensive
system examination and testing “at home” in the warehouse or other appropriate location at regular intervals. Such at home
examinations and tests should occur at least once a year, and should include a careful inspection of each component under
ideal lighting conditions, and then a final comprehensive check of the entire system after it has been flown.
If any anomalies or defects are discovered that could possibly affect the safety or integrity of the system, affected parts or
subsystems should be replaced in their entirety before that part of the system is flown again.
REPLACEMENT PARTS
Any component found to be defective, or any safety-related component you even suspect might be defective, should be re-
placed with the equivalent, approved part. Parts specific to a QuickFly system should be ordered directly from Meyer Sound.
No attempt should be made to substitute what appears to be equivalent or “mostly the same” generic replacements. Some
parts used in QuickFly systems are identical to those used in other rigging applications. To the best of our knowledge, most
of these suppliers are reputable and their products are reliable. However, Meyer Sound has no way of assuring the quality of
products made by these various suppliers. Therefore, Meyer Sound is not responsible for problems caused by components
that were not supplied by Meyer Sound.
TRAINING
QuickFly systems are relatively straightforward and easy to use. However, they should only be used by persons trained in the
use of loudspeaker rigging systems who have mastered key points of assembly, rigging and flying. Users should read this
manual in its entirety before attempting to deploy any QuickFly system. You may make additional copies of this manual as
necessary for in-house use; copies may not be made for any other purpose.
