The end columns are located at both ends of the bridge and bear the core responsibility of transferring the bridge load to the supports. This component is designed with two types of ends, male and female, and must be connected to the truss ends in a complementary manner during installation.

In terms of structural details, the end column integrates multi-dimensional connection functions: the double circular holes on its side wall are used to lock the truss chords, the elliptical holes at the top provide an interface for the addition of double-layer trusses, and the short cantilever at the bottom, together with the positioning pin and movable iron buckle, ensures the stable placement of the crossbeam.
