The main beam and the end beam are rigidly connected, and the two ends of the end beam are equipped with wheels to support the bridge to run on the elevated. Rails are welded on the main beam for the trolley to run. There are more typical structural types of bridge main beams, such as box structure, four truss structure and hollow truss structure.
