DEPLOYMENT BY HELICOPTER (Contd)
6. Determine and prepare site for bridge (2) emplacement. Refer to Site
Requirements and Layouts, WP 0012 00.
7. Secure all loose equipment with tape or tie-straps, and check all latches to
ensure they are securely fastened
NOTE
Since bridge is symmetrical in design, either end can be
designated as the front to be flown forward. The chains
connecting the forward sling set to the bridge will be set at
the third chain link. The chains connecting the aft sling set
to bridge will be set at the twenty-fifth chain link.
8. Position two sling legs (2) on bridge half (1), and connect two sling legs (2) to
apex fitting (3) with coupling link (4).
9 Position chain (9) through helicopter lifting ring (10) on both sides of bridge
half (1).
10. Loop two chains (9) through sling legs (2) and connect chain grab-hook (11) on
third link from end of chain at both sides on bridge half (1).
11. Position two sling legs (5) on bridge half (8), and connect two sling legs (5) to
apex fitting (6) with coupling link (7).
12. Position chain (9) through helicopter lifting ring (10) on both sides of bridge
half (8).
13. 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).
14. Secure all excess chain with 2-in. (51-mm) wide tape or Type III nylon cord.
15. 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.
16. 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.
