Axial Tension Testing Forged Horizontal Connectors for Use with Intermodal ISO (International Organization for Standardization) Containers

摘要

The Marine Corps Container System and the Marine Corps Expeditionary Shelter System, both of which are part of the Marine Corps Field Logistics System (FLS), use intermodal shipping containers that meet the standards of the International Organization for Standardization (ISO). Horizontal connectors are used to couple these containers for shipping by sea, highway, or rail. To detemine whether a certain commerically available horizontal connector meets the tension resistance requirements for coupling intermodal shipping containers, four identical connectors were statically tested at a standard loading rate in a tension testing machine. The connectors were pulled by standard ISO corner fittings which, in turn, were pulled by the machine. Maximum applied forces were measured, recorded, and then compared with the rated capacity. The results of a static test to determine whether a forged Tandemloc Inc. Horizontal Connector meets the tension resistance requirements for use with International Organization for Standardization (ISO) containers in the Marine Corps Container and Expeditionary Shelter Systems are presented. Four identical connectors were tested. The maximum applied forces were measured, recorded and then compared with the rated capacity. The connector met the tension resistance requirements and should be qualified for use in the container and shelter systems.
