WARNING: The array should always be level side-to-side.  This should be monitored and adjusted

as needed throughout the rigging procedure to prevent the array from swinging sideways as the

array s weight is being taken by the chain motors.  Personnel near the array must be aware that

this can and will happen and should position themselves appropriately to prevent injury or death.

CAUTION: During the following procedures, insert all short connecting pins from the inside of the

Hinge Tubes.  Inserting the 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.

IMPORTANT  NOTE:  With  the  exception  of  connecting  pins  used  to  lock  the  hinges,  connecting  pins

should be inserted into one of the bottom holes of each enclosure s four hinge tubes.  This is true whether

the  enclosure  has  anything  attached  beneath  it  (another  enclosure  or  a  pallet)  or  not.    Failure  to  follow

this rule will result in either lost connecting pins or connecting pins not available when and where they are

needed during load-in and load out procedures.

IMPORTANT NOTE FOR SPLAYED ENCLOSURES:  Two of the six short connecting pins supplied with

each KF760 and KF761 are intended as hinge locking pins when the rear of the enclosures are splayed 

and  the  Pull-Back  Bar  is  used.    Normally  gravity  keeps  the  rears  of  splayed  enclosures  apart,  thus

maintaining  the  splay.    When  a  Pull-Back  Bar  is  used,  it  creates  an  upward  force  on  the  rear  of  the

enclosures, tending to push the rears of splayed enclosures together, thus collapsing the splay.

The solution is to lock the hinge in the top of the bottom enclosure between any two splayed enclosures. 

To do this, insert a connecting pin into the top hole of the each rear Hinge Tube and through the bottom

of the hinge. This prevents the hinge from moving back down into its own Hinge Tube when an upward

force is applied to the rear of the enclosure.  When enclosures are tight-packed using the Pull-Back bar,

the hinge locking pin is not needed.

2.1

PICK POINTS

Establish and rig the two pick points for the array with chain motors rated for the load.

If a pull back is used, establish and rig three pick points with chain motors rated for the load.

2.2

FLY-BAR ASSEMBLY

1.    The  Fly-Bar  is  assembled  by  attaching  the  Spreader  to  the  Rigging  Bars.    Use  two  long  connecting

pins at each end of the Spreader to attach it to the Hoisting Ring collets.  If the pull-back Tail Bar is to be

used,  insert  the  Tail  Bar  arm  into  the  sleeve  in  the  center  of  the  Spreader  and  secure  with  two  long

connecting pins. 

2.  The front-to-back Spreader position is determined by using the KF760 Wizard software.  Position the

Spreader Bar as indicated by the Wizard.

3.  Attach the Fly-bar to the chain motors using the two hoisting rings on the Rigging Bar.

Ensure the Hoisting Ring Collets are attached to the Rigging Bar with two long connecting pins each.

Ensure the Spreader is attached to the Hoisting Ring Collets with two long connecting pins at each end.
