The invention discloses a lightweight beam bottom inspection vehicle which is characterized in that the beam bottom inspection vehicle comprises a portal frame, a middle truss and a side truss, the cross section of the middle truss and the cross section of the side truss are of a triangular structure, and the middle truss and the side truss are fixed to the two sides of the portal frame through pin shafts respectively and obliquely pulled on the portal frame through inhaul cables respectively. A series of problems caused by a complex truss structure and an installation mode of an original beambottom inspection vehicle are well solved, the truss adopts a triangular section, the structure is simple and more stable, the truss structure is simplified, the lateral windward area of the truss isreduced, and the weight of the truss is greatly reduced; the middle truss, the side trusses and the portal frame are connected through the pin shafts, the structural form simplifies the connecting mode of the trusses and the
