TRANSPORTER OPERATIONS SITE SURVEY
Prior to performing transporter operations, ensure a
site survey is conducted. Failure to meet all site
requirements for a given launch method may result in
damage to equipment or possible injury or death to
A site survey must be conducted to establish a suitable launch site prior to
launching bays and performing bridging or rafting operations. (Refer to
WP 0019 00, Site Requirements and Layouts.) Site selection should be established
by reconnaissance, and the operator is responsible to observe the following
requirements and conditions prior to entering the site with a transporter.
Two ground guides must be present for all bridging
operations. Failure to use ground guides may result in
crashing the transporter into an obstruction or coming
in contact with power lines resulting in damage to
equipment or injury or death to personnel.
a. A ground guide is required to assist the operator when maneuvering the
transporter and while performing launch and retrieval operations.
Gravel and small rocks on roadway surface leading to
bridge can cause dents and punctures in bridge
roadway deck and can also become lodged in ramp and
interior bay unfolding mechanisms causing jamming
during bay retrieval. If gravel or small rocks are
present at bridge or raft site, either remove them or
cover them with topsoil or sand.
b. The launch site ground surface should be firm and clear of any obstructions
such as gravel, small rocks, and low hanging trees or power lines.
c. The overhead clearance above loading areas must be at least 22 ft, 2 in. (6.7 m).
d. The river bank incline should not be greater than the specified limit for the
launch method used. (Refer to WP 0019 00, Site Requirements and Layouts.)
e. The river bank side-to-side slope should be no greater than an 8% grade
Water fording depth should not exceed 4 ft (1.2 m) or
damage to equipment may result.
f. Water depth for fording CBT should not exceed 4 ft (1.2 m).
