2–16. High Bank Launch of Bay. A high-bank launch of a bay may be necessary at various times. This method
makes possible the launching of a bay from up to a 28 ft (8.5 m) vertical riverbank. This method should only be used if
no other method of launching can be performed. Prior to launch, a thorough inspection of the area should be made to
ensure the bank will support the transporter and bay to permit safe operation. The crew required for a high-bank launch
will consist of an operator and an assistant. The operator will drive and be responsible for the operation of the boom and
winch. The assistant’s duties will be to handle the winch cable and give signals to the operator during launch. Both operator
and assistant will prepare the bay for launch, with the operator responsible for the completion of the tasks. A minimum
of 17 in. (43.2 cm) of water is required for unfolding a bay. The entire operation will generally take place at the launch site.
NOTE
A high-bank launch consists of two distinct phases. The first being the off load onto the ground and the
second the actual launching.
(1) Position transpoter parallel to river bank allowing enough room, at least 25 ft (7.62 m) for ramp bay or 28
ft (8.54 m) for interior bay, to maneuver transporter and place transpoter in neutral.
(2) Model (RBT) install bogie bracket (1) between rear axle housing (2) and frame rails (3), and install rubber
bumpers (4) on aft tiedown hooks (5).
