Follow these steps to detach the antenna from the
pallet and safely rig the antenna for crane
hoisting.
a.
Using a 7/16" socket/ratchet or nut driver,
unlock the three hex latches securing each of
the antenna’s service hatches (see Figure 19).
Then gently lower the hatches. You can now
access the four shipping bolts securing the
antenna’s baseplate to the pallet.
b.
Using a 3/4" socket/ratchet or wrench,
remove the four outer 1/2"-13 bolts securing
the antenna to the pallet (see Figure 20). Do
not remove the four inner bolts that secure
the internal antenna assembly to the
baseplate.
c.
Close both antenna service hatches. Secure
each hatch using the three hex latches.
d.
Secure the crane rigging to the antenna’s four
lift brackets (see Figure 21). Be sure the
rigging and crane are suitably rated to safely
lift the 240 lbs (109 kg) antenna.
e.
Carefully hoist the antenna to its mounting
location.
WARNING
Be sure no personnel stand underneath the
antenna at any time while it is suspended in
the air.
Take protective measures to avoid gouging or
scratching the radome during the rigging
operation.
