HIGH-BANK LAUNCH OF BAY
A high-bank launch is performed where launch site
conditions require the bay to be slowly lowered into the
water from a height of 528 ft (1.58.5 m) with the
transporters LHS and BAP winch, and then unfolded
by manually releasing the bays travel latch with a
lanyard. Ensure launch site conditions are met or
damage to equipment may result.
Assistant will act as a ground guide when maneuvering
CBT and during operation of the LHS. Failure to
comply may result in damage to equipment.
During all transporter operations, the CBT operator
will drive and be responsible for the operation of the
LHS via the cab control box or remote control unit. The
assistant will act as a ground guide, be responsible for
directing the operator using hand signals, and assist
the operator as needed.
To perform a high-bank launch, the transporter winch
must be fitted with the HEMTT 20 ton snatch block
(BII, TM 9-2320-279-10) and the winch extension
assembly (AAL, TM 5-5420-234-14&P). Use the IRB
hoisting gear (lifting sling) only for lifting bays
(WP 0070 00, Item 4).
a. Ensure launch site conditions exist for a high-bank launch of bay
(WP 0019 00, Launch Condition Requirements). If launch site conditions do
not meet requirements for a high-bank launch, refer to Deployment by
Helicopter (WP 0027 00) or Operation Under Unusual Conditions
(WP 0045 00).
b. Back up CBT parallel to river bank approximately 8 ft (2.5 m) from edge of
bank, then apply service brake (3), move transmission selector lever (2) to N
(neutral), and pull PARKING BRAKE control (1) out.
c. Unload bay to ground (WP 0023 00, Unloading Bay to Ground).
