The utility model relates to the technical field of hydraulic power plant dam portal cranes, and discloses a cart traveling mechanism of a hydraulic power plant dam portal crane, which is characterized in that a speed reducing motor is mounted at the output end of a traveling wheel and is flexibly connected with a crane frame through a flexible supporting force arm; the first nut pin shaft and the second nut pin shaft are inserted in a penetrating manner through a stress pull rod, and the arm rod end of the stress pull rod is sleeved with a compression spring right opposite to the position between the speed reducer connecting seat and the crane connecting seat. According to the utility model, the flexible supporting force arm is adopted as the flexible connecting point of the speed reducing motor and the crane frame, so that the overlarge load generated by inertia of the walking wheels when the cart walking mechanism stops can be unloaded in a flexible connecting manner, and the unbalanced load generated when
