[0003] Existing prefabricated walls are provided with a number of positioning holes on the bottom surface of the wall. When the construction workers install the prefabricated wall, they will first set a number of positioning steel bars on the ground, and use the crane to move the wall so that the positioning steel bars enter the positioning holes to achieve the installation of the wall. During this process, the crane has been hanging the wall to keep the wall stable. The construction workers need to install a number of temporary support rods on one side of the wall to keep the wall stable. After the wall is stable, the crane can be separated from the wall.
