The utility model discloses a novel road-crossing cable supporting frame which comprises a stand column, a winder is arranged below the stand column, and the winder is connected with a clamping device through a traction rope. The clamping device comprises a movable frame, a guide hole is formed in the movable frame, and a buffering piece is installed in the guide hole in a sliding mode. The buffering piece comprises a guide rod sliding in the guide hole, and the guide rod is sleeved with a spring. After the cable is clamped by the buffer piece, the clamping device is moved to the upper end of the stand column through the winder, so that the cable is lifted away from the ground; when the cable is shaken by wind, the guide rod promotes the spring to contract, and after the external force disappears, the spring can promote the cable to reset, so that the cable can be prevented from being strained in the shaking process by utilizing the matching of the guide rod and the spring while the cable can conveniently cross the road surface, and the cable is protected; in addition, hoisting of the cable is completed through the winder, and the structure of the equipment can be simplified while the cable is hoisted conveniently.
