The invention discloses a lifting bearing platform of a subway and inter-city train. 26-30 connecting beams 5 are installed between a main beam I4 and a main beam II6; 10-15 rectangular steel tubes I0 are installed between each two connecting beams 5; a suspension beam I3 and a suspension beam II7 are installed on corresponding connecting beams 5 outside the main beam I4 and the main beam II6; the central lines of both the suspension beam I3 and the suspension beam II7 coincide with the central lines of the connecting beams 5; a manhole cover 9 is installed at the inner side of each connecting beam 5 at two ends of the bearing platform. The lifting bearing platform of the subway and inter-city train not only guarantees requirements on the use performances, but also saves materials and reduces investment by the adoption of an integrated box type beam welding framework structure and the structural design for mechanical data output by each component which composes the bearing platform based on the calculation programs of a computer when the bearing platform is in a load state.
