The present invention relates to a device for preventing an A-shaped aluminum ladder from tipping over. The device for preventing an A-shaped aluminum ladder from tipping over comprises: four support rods whose inner ends are mounted on lower ends of a first post and a second post; rod fixing holes installed on the lower ends of the first post and the second post at equal intervals; four links each having a first end mounted on a middle portion of each support rod and a second end; and four fixing members connecting the links to the first and the second post by coupling the seconds ends of the links and the rod fixing holes of the first and the second post. The four support rods are attached to a floor, and the links are connected in an angle to improve safety of the device for preventing an A-shaped aluminum ladder from tipping over. A lateral rod such as a hook is installed to correspond to an outer wall of any one among the first and the second post. When the lateral rod protrudes above the A-shaped aluminum ladder, a user can hold the lateral rod and stably stand up. Also, a hook of the lateral rod can be used to hang a tool pocket of a worker. |
