Operation of the CBT and BAP under usual conditions is described in this
section. Operation under unusual conditions is described in WP 0045 00,
Section IV. Prior to operating the CBT, the operator must perform the following:
The Bridge Modules have a relatively high center of
gravity and can affect the common bridge transporter
(CBT) dynamic performance. The CBT carrying a ramp
bay or interior bay can be operated on improved roads
at a maximum speed of 37 mph. If traversal of cross-
country terrain is necessary to access an operation site,
limit CBT speed to 15 mph or less.
a. Review the HEMTT vehicle operating instructions prior to driving the CBT;
refer to TM 9-2320-279-10.
