Figure 10:
Flying with Front Dollies
The two boxes must be held parallel during the installation of the rigging hinge. If there is a slight
vertical misalignment that causes the hinge to bind during installation, either the suspended box
or the box on the dolly may be manually lifted to facilitate the hinge installation. Once both rear
hinges are secured, the array is lifted until the box on the Front Dolly is no longer contacting the
ground.
The Front Dolly is then removed from the bottom box. Do not attach the front Xvsl rigging straps
yet on the bottom box. The array is then raised and another box on a Front Dolly is rolled into
position from behind the array. The two Xvhl linking hinges are then simultaneously installed in the
rigging on the suspended box and the box on the dolly as previously described.

Step 2: Roll one box with the front
dolly into position and lower the
array to align the bottom box in the
array to the box with the front dolly.
Install the rear hinges one at a
time. To ease installation the
boxes must be held parallel. Lift
the suspended box or the dolly box
as necessary to facilitate the hinge
installation.
Step 1: Attatch one or more boxes
to the grid using two grid straps at
the front and two grid straps at the
rear. Lift the array.
Step 7: Roll another box with the
front dolly into position and lower
the array to align the bottom box in
the array to the box with the front
dolly. Install the two rear hinges
and two front straps as described
in step 2.
Step 3: Remove the dolly pin and
lift the array. Remove the dolly.
Step 4: Roll the next box on a front
dolly into position. Lower the array
and install the two rear hinges
between the bottom array box and
the dolly box as done in step 3.
Step 5: Remove the dolly pin and
lift the array. Remove the dolly.
Step 6: Swing the next-to-bottom
box up and attach the two linking
straps at the front to the box
above.
Step 8: Remove the dolly pin and
lift the array. Remove the dolly.
Step 9: Swing the next-to-bottom
box up and attach the two linking
straps at the front to the box
above. Repeat steps 7, 8, and 9
until as necessary to build the
array.

and attach the two linking straps at
the front to the box above.
