RIGGING

KF730 Series arrays are intended to be suspended or ground-stacked. This chapter details how
to physically configure KF730 Series arrays. The following are the recommended methods for
most situations. Specific situations may require other methods. It is the user's responsibility to
determine the viability and safety for alternate methods and implement them accordingly.
KF730 and SB730: The procedures to suspend and ground-stack KF730s and SB730s are
detailed in this chapter.
KF730P and SB730P: The procedures to suspend and ground-stack permanently installed
KF730Ps and SB730Ps are detailed in instructions provided with the KF730P and SB730 Splay
Bracket Kits. Use those instructions for rigging any KF730P and SB730P products and their
accessories.

RIGGING WARNINGS

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 arrays overhead.
Failure to follow these precautions may result in damage to the equipment, injury, or death.
DANGER: When suspending or stacking KF730s and SB730s, avoid placing any parts of the
body between the enclosures or between an enclosure and the Fly-bar. Always use the integral
handles to lift or position enclosures. Failure to follow this precaution may result in damage to the
equipment, injury, or death.
CAUTION: A KF730 weighs approximately 77 lb / 35 kg. This, along with the physical size,
means that one person may be able to lift and carry it. However, always use proper lifting
techniques to avoid injury. Use good judgment to determine if you need lifting assistance such as
another person, a back support belt, or mechanical assistance. Because it weighs approximately
111 lb / 51 kg, always use two people or mechanical assistance to lift an SB730.
IMPORTANT RIGGING NOTE: Each Quick Release Pin, used to attach enclosures together, can
be inserted into one of several holes in both the Hinges and Hinge Tubes integral to the
enclosures. The particular holes used set the splay angle between the enclosures and thus their
aiming. Use the correct holes as determined by the KF730 Wizard or as desired by the user.
IMPORTANT TRANSPORTATION NOTE: To avoid damage to the Quick Release Pin handles
when transporting, always insert the pins from the inside of the Hinge Tubes. This keeps the
Quick Release Pin handles from extending beyond the footprint of the enclosures or Fly-Bar.

SUSPENSION LOAD RATING - WORKING LOAD LIMIT (WLL)

The Fly-Bar has a WLL for suspending a maximum of eighteen (18) KF730s or a maximum of
twelve (12) SB730s. The design factor for this rating is 8:1.
KF730s and SB730s may be flown in the same array. The WLL (Working Load Limit) for any
combination of KF730s and SB730s is 1500 lb / 680 kg. For such combinations, use these
formulas to determine maximum allowable quantities of each model. In all cases, round the
answer DOWN to the nearest integer. This will keep the total weight of the KF730/SB730
combination within the specified WLL with at least a 100 lb / 45 kg margin for the weight of
loudspeaker cables, Pull-Bar, or other additional loads.
