PURPOSE: A gate dogging device is provided to prevent a safety accident caused by the fall of a gate by maintaining the dogged state of the gate. CONSTITUTION: A gate dogging device comprises multiple hanger devices(100) and fixing devices. The hanger devices dog a gate. The fixing devices touch the compression surfaces of the hanger devices. Each hanger device comprises a support(110), multiple fixing blades(120), fixing ribs(130), front and rear stoppers(170,170'), and a tension spring(115). The fixing blades allow the support to be moved in a horizontal direction. The fixing ribs are coupled to the fixing plates of the fixing blades. The front and rear stoppers restrict the movement of the fixing blade. The tension spring elastically compresses the support to the front stopper. |
