EXTERNAL CARGO HOOK SYSTEM
(Continued)
16-1
Manual Release Without 35
Manual release of the center cargo hook is done by
pulling a D-shaped ring at the top front of the hook.
Pulling the D-ring releases a cam lock mechanism,
allowing the hook to pivot open. Switch S2 closes to
light the MID HOOK OPEN capsule on the master
caution panel. The hook is reset manually by pushing
up on the tip to lock the cams into position. When the
hook is reset, switch S2 opens and the HOOK OPEN
light goes out.
NO BREAK - WORK HARDER
Manual release of the forward and aft hooks is done by
the handle in the rescue hatch. Pulling the handle aft
rotates a lever arm in each hook. This frees a latch to
pivot away from the load beam (hook). The weight of
the load is then free to pull the load beam open and the
load drops. At the same time, an actuator in the hook
linkage lights the FWD and AFT HOOK OPEN lights on
the master caution panel. The hooks then return to the
closed and latched position and the lights go out.
Manual Release With 35
Manual release of the center, forward, and aft cargo
hooks is accomplished by using the handle in the rescue
hatch.
NO BREAK - WORK HARDER
Pulling the handle aft releases a cam lock mechanism,
allowing the center hook to pivot open. Switch S2 closes
to light the MID HOOK OPEN capsule on the master
caution panel. The hook is reset manually by pushing
up on the tip to lock the cams into position. When the
hook is reset, switch S2 opens and the HOOK OPEN
light goes out.
NO BREAK - WORK HARDER
Pulling the handle aft also rotates a lever in the forward
and aft hooks. This frees a latch to pivot away from
the load beam (hook). The weight of the load is then
free to pull the load beam open and the load drops. At
the same time, an actuator in the hook linkage lights
the FWD and AFT HOOK OPEN lights on the master
caution panel. The hooks then return to the closed and
latched position and the lights go out.
