M-2 Bailey Bridge (M2BB) Palletization and Containerization Load ConfigurationStudy

摘要

This report addresses the Palletized Loading System (PLS) Flatrack and ISOContainer Load Configurations for the M-2 Bailey Bridge (M2BB) Basic Set and Erection Equipment Set. The M2BB Basic Set contains enough components to install two 80-foot double-single (DS) bridges with launching nose or one 130-foot double-double (DD) bridge with launching nose. The optimum arrangement of M2BB components on PLS flatracks or ISO containers was determined through the use Computer Aided Modeling (CAM) of the M2BB components, PLS flatrack, and ISO container. The results of the study are that components of the M2BB Basic Set and Erection Equipment Set can be loaded on two M1077 PLS flatracks and eighteen M1 PLS flatracks or in two 40-foot ISO containers and eighteen 20-foot ISO containers. Some of the palletized and containerized loads are well below the payload limits; and the flatracks and containers for these loads still have room for the overhead bracing supports and components of the M2BB Conversion Set and Cable Reinforcement Set. If these components are required, there will be no need for extra PLS flatracks or ISO containers. The resulting load configurations must be verified by tests before their use. Tiedown procedures for palletization and containerization should be documented in detail during testing. These documented tiedown procedures should be incorporated into the M-2 Bailey Bridge manual.
