In the utility model, under the action of the two wing-type support members, the stability of the cable bridge when installed on the hanger assembly can be improved, the technical problem of tilting of the hanger assembly due to uneven stress on both ends of the cable bridge and the consequent falling of the cable bridge can be effectively avoided, and the cable bridge can be fixed, so that the cable lines can be fixed after being installed in the cable bridge, and the technical problem of displacement of the cable lines in the cable bridge can be overcome.

[0004] However, the above-mentioned prior art still has certain limitations. The bridge support method of the support hanger is a cladding design, especially the setting of the clamping beam, which improves the stability of the bridge, but when the bridge needs to be disassembled and repaired, the staff must first disassemble the support hanger to move the bridge out, increasing the complexity and workload of maintenance. In the running process of the bridge, the closed design at the bottom effectively protects the cables, but when the cables fail, it is not convenient for the staff to quickly find the problem location, further prolonging the maintenance time. In view of this, we propose a bridge and support hanger convenient to install and maintain. UTILITY MODEL CONTENTS
