While many designs have achieved the core function of collapsing, an ongoing limitation has been that they are still treated as individual units. This means they save in storage and transport but are still required to be handled individually. To ensure the system is simple, efficient, affordable and safe, COLLAPSECON is designed to be collapsed/expanded using the COS. Most importantly, every container is only touched once in the process, thereby reducing the overall handling requirement. Additionally, each unit combines using the end frames which means there are no external parts. When combined, four units can be treated as a single unit.
