Section I. GENERAL
a.
Introduction. The construction (assembly) and delaunch (disassembly) of double story bridges are
described in step by step procedures in this chapter.
The assembly procedures start with the setting up and alignment of the roller beam, followed by step by step
assembly instructions to construct the bridge. Similarly, disassembly procedures contain full step by step instructions.
Disassembly is not the exact reverse of assembly; there are differences, therefore the step by step procedures shall be
followed carefully. These procedures are covered in more detail in Chapter 4 General Drills. The operator should be
familiar with these drills before following the step by step procedures in this chapter.
When familiarity is gained with the general drills and the step by step procedures, any double story bridge can be
assembled using the Build and Boom Tables, and disassembled using the Delaunch Tables.
NOTE
Do not attempt to use the Tables until the general drills and step by step procedures have been
practiced a number of times.
