b. FixedAnchorage. If the ribbon bridge is to remain in place for long periods of time, it is desirable to anchor the
bridge using a fixed-type anchorage system. The most common type is an overhead cable with bridle lines and approach
guys. Refer to TM 5-210 for assembly and installation instructions for various types of fixed anchorage configuration.
Refer to figure 2-23, for typical bridle line connection to bow lifting and anchoring pins. The components necessary to erect
the standard overhead cable system are supplied in the ribbon bridge supplemental set SC-5420-97-CL-E51.

c. Short Term Anchorage. The rapid assembly charactetistics of the ribbon bridge requires that bridge boats be used
to hold the bridge in place (fig. 2-24). The length of time the bridge is to remain will determine whether a fixed anchorage
system will be installed later. The number of bridge boats required to anchor the bridge is shown in table 2-15. Boats must
be checked for fuel consumption every two hours and refueled as necessary. At least two standby boats must be available
for replacing disabled boats.
Stop bridge traffic while replacing boats.
