| description | The utility model discloses a maintenance hanging ladder based on bridge performance safety. The device structurally comprises a hook, a first connecting column, a first transverse rod, a second transverse rod, a bottom frame, a third transverse rod, a second connecting column, a telescopic device and a bottom plate device; the lower end of the hook is inserted into the upper end of the connectingcolumn; the right end of the connecting column is welded with the left end of the first cross rod; the first cross rod is arranged at the upper end of the second cross rod; the utility model discloses a maintenance hanging ladder based on bridge performance safety. Telescopic device, push button pushed rightwards, spring compression, the bolt extends out of the insertion hole and moves rightwards; the first telescopic rod slides into the second telescopic rod; by arranging the telescopic device to contract, the problem that storage is inconvenient due to the fact that stretching and contracting cannot be conducted is |
