CONNECTING PINS
Two types of connecting pins are used with a KF760 array. The 1-1/4 inch or short connecting pins are
used for all enclosure to enclosure and enclosure to Fly-Bar connections. The 4 inch or long connecting
pins are used to connect Fly-Bar components together and secure the casters to the caster pallets. Both
types are single acting, double ball pins with a minimum double shear strength of 20,000 lb / 9,000 kg.

CAUTION: Insert all enclosure connecting pins from the inside of the Hinge Tubes. Inserting the
connecting pins from the outside of the enclosure into the Hinge Tubes can and will result in
jammed pins. This is because the hole dimensions and clearances are not designed for inserting
the pins in this direction.

RIGGING PREPARATION
It is very important to properly prepare the Fly-Bar, enclosures, and Tail Bar or Pull-Back Bar for rigging.
If incorrectly configured beforehand, it will be more difficult and less efficient to rig an array and required
parts may get lost. In the following checklist, the locations of the connecting pins are where the pins
should normally be locked in for storage or transportation in anticipation of rigging an array. Following
this scenario, connecting pins will always be available where they are needed for the purposes listed.
The only exceptions are the two extra short connecting pins shipped with each enclosure used for locking
the hinges when the Pull-Back Bar is used. These are normally stored loose .
1.4.1
KF760 and KF761 Enclosures:
1. Leave a short connecting pin in the bottom hole of each Hinge Tube on each enclosure.
Use these to:
Attach an under hung KF760 or KF761 by engaging its four hinges.
Attach a KF760 on a pallet to the one below it by engaging its four hinges.
2. There are two additional connecting pins intended for locking the hinges provided with the KF760s and
KF761s. Do not store these in their rigging because the only places to put them will be in the way when
rigging. Store these pins loose where you will not lose them.
3. Do not leave connecting pins in any other holes other than as in #1.
1.4.2
Fly-Bar:
1. Leave a short connecting pin in the bottom hole of each Hinge Tube on the Fly-Bar. Use these to:
Attach the top KF760 or KF761 enclosure of the array to the Fly-Bar.
2. Leave four long connecting pins in each Hoisting Ring Collet. Note: these pins normally would be in
use if the Fly-Bar were left assembled. Use these to:
Attach the Hoisting Ring Collet to the Rigging Bars.
Attach the Hoisting Ring Collet to the Spreader.
1.4.3
Assembled Fly-Bar Left Connected to Top of a KF760 for Transportation and Storage
1. Lock the top enclosure s four hinges in their extended (up) position using the top hole in each Hinge
Tube and the bottom hole in each hinge. Use four short connecting pins for this. This will keep the hinges
from dropping into the Hinge Tube and thus keep the Fly-Bar from contacting the top enclosure.
