The invention discloses a low-floor tramcar underframe structure, which comprises an underframe body. The underframe is formed by sequentially welding a first-position end structure, a middle sleeperbeam structure, an aisle structure and a second-position end structure from front to back, the front-back length of the underframe is 5420mm, the left-right width of the underframe is 2504mm, and theheight of the underframe is 760mm; and a lower hinge seat and a rotary stop seat are fixedly welded at an outer end center of the aisle structure. The low-floor tramcar underframe structure meets therequirements for installation of various devices of a tramcar body, ensures stable operation of the tramcar, can meet the requirements for various loads generated during operation of the tramcar, andmeanwhile meets the requirements for axle load of the tramcar body, low cost, simple structure and convenient manufacturing.
