The invention relates to the technical field of portal crane equipment, in particular to a suspension type wheel edge brake for a portal crane. The suspension type wheel edge brake for the portal crane comprises a supporting frame, a clamping assembly, a force increasing mechanism, a reverse transmission assembly and a linear driving device. The clamping assembly is arranged below the supporting frame, and the clamping assembly is used for clamping a track so as to achieve a braking effect. The force increasing mechanism is arranged above the supporting frame, and the force increasing mechanism is used for controlling a pair of working ends of the clamping assembly to move horizontally. The reverse transmission assembly is rotationally connected with the supporting frame, the input end of the reverse transmission assembly is connected with the output end of the force increasing mechanism, the output end of the reverse transmission assembly is connected with the input end of the clamping assembly, and the reverse transmission assembly is used for reversely transmitting force output by the force increasing mechanism to the clamping assembly. The output end of the linear driving device is connected with the input end of the force increasing mechanism, and the linear driving device is used for providing driving force for the force increasing mechanism. According to the scheme, the powerful braking effect can be effectively provided, and the structure is safe and stable.
