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.
