6. RIGGING
WARNING: Suspending anything, especially overhead of people, should be done with extreme
caution. Always engage the services of a certified professional who is qualified to determine the
requirements for and to implement overhead rigging. Only persons with the knowledge of proper
hardware and safe rigging techniques should attempt to suspend KF730 Series loudspeaker systems
overhead. Failure to follow these precautions may result in damage to the equipment, injury, or death.
KF730 Series arrays are intended to be suspended or ground-stacked. This chapter details how to
physically configure a KF730 Series array.
6.1 RIGGING LOAD RATING (WLL)
The KF730, SB730 and Fly-Bar rigging has a WLL (Working Load Limit) for suspending a maximum of
eighteen KF730s or a maximum of 12 SB730s. The design factor for this rating is 8:1.
6.2 RIGGING RECOMMENDATIONS
6.2.1 Attachment to the Fly-Bar
The KF730 Fly-Bar design permits several methods of attachment.
1. Center Holes:
• Use one of these holes for single point attachment, the particular hole being dictated by the KF730
Wizard to result in the correct array tilt angle.
• Use one hole in the rear and one in the front for bridling to a single point.
• Use one hole in the rear and one in the front to attach two chain motors.
2. Corner Hoisting Points:
Use in pairs, side to side, to bridle to single front and rear points for attaching two chain motors.
6.2.2 Rigging Methods
The two recommended rigging methods are:
1. Employ one chain motor, attached to particular Center Hole dictated by the KF730 Wizard
• This will automatically result in the correct array tilt angle when all enclosures are flown.
• One motor may be easier to deploy than two.
2. Employ two chain motors, one attached to the front of the Fly-Bar and the second to the rear.
• The attachment can be to the Center Holes or the Corner Hoisting Points.
• The array will be easier to assemble because it allows tilting the enclosures already suspended to
better match the angle of the next enclosure(s) to be attached.
• Once assembled, the overall tilt angle for the array can be easily adjusted, if needed.
6.3 ENCLOSURE TO ENCLOSURE ATTACHMENT
6.3.1 Splay Angles
The splay angles required between each enclosure to achieve the desired array curvature are set by the
integral rigging hardware. The hardware consists of square Hinge Tubes each with a sliding Hinge on each
of the four enclosure corners.
6.3.2 Basic Attachment Procedure
With the enclosures near or in contact, slide the Hinges into the Hinge Tubes of the enclosure or the Fly-
Bar above it. Connect the Hinges to each of the four Hinge tubes using the supplied connecting pins.
CAUTION: To avoid pin damage while moving or transporting the enclosures, always insert the pins from
the inside of the Hinge Tubes.
