BRIDGE RETRIEVAL (Contd)
Depress RETRIEVAL button (2) to confirm and step into next function.
Ensure slack from winch wire rope is removed before
confirming next function.
Ensure guide pins at end of launch beam are aligned in
channel on A-frame prior to releasing hold button. Once
guide pins are aligned in channel, observe bridge
assembly raise 1.5 in. (2638 mm) prior to confirming
Depress and hold ACTION 2 button (1) to R7-H-RETRIEVE BRIDGE FROM
GAP, and observe bridge assembly (4) as follows:
a. Observe bridge assembly (5) align and engage with launch boom pin
b. As bridge assembly (5) is driven toward pallet A-frame (3), observe
play-in of winch wire rope (4) at same rate.
Release ACTION 2 button immediately if launch boom
does not lift bridge to pre-stressed position after lower
couplings have passed yellow mark. Failure to comply
will result in damage to needle cam follower bearings
when upper coupling remote control arms contact
release levers on pallet. Refer to troubleshooting, WP
c. Observe launch boom (6) is lifted when bridge lower couplings (10) pass
yellow mark (9) at end of pallet frame girder (7). Travel of bridge
assembly (5) will stop while launch boom (6) is lifted, and will continue
once launch boom (6) has reached its pre-stressed position.
d. Observe tip (8) of bridge assembly (5) raise 11.5 in. (2638 mm) after
reaching A-frame (3).
