10. Loop two chains (9) through sling legs (5) and connect chain grab-hook (11) on
twenty-fifth link from end of chain at both sides on bridge half (8).
11. Secure all excess chain with 2-in. (51-mm) wide tape or Type III nylon cord.
12. Cluster and tie or tape all sling legs above bridge to prevent fouling during
hookup.
NOTE
The hookup team kneels on top of the load. The static
wand person discharges the static electricity with the
static wand. The forward hookup person places apex
fitting 1 onto the forward cargo hook. The aft hookup
person places apex fitting 2 onto the aft cargo hook.
The hookup team then carefully dismounts the bridge
and remains close to the load as the helicopter removes
slack from the sling legs. When successful hookup is
assured, the hookup team quickly exits the area
underneath the helicopter to the designated rendezvous
point.
13. Bridge supervisor will signal helicopter pilot to position helicopter directly over
bridge (2).
WARNING
Ground helicopter connecting ring prior to
connecting/disconnecting. Static electricity generated
from helicopter will shock personnel and injury or death
may result.
CAUTION
Ensure all four bridge quarter slide locks are locked by
visually checking position of control levers and feeling
each lock lever for engagement on launch beam support
tubes. Failure to comply may result in damage to
equipment.
14. Connect apex fittings (3) and (6) to helicopter forward and aft hooks, and signal
helicopter pilot to slowly lift bridge from ground or gap.
