ABSTRACT:
A wall lifter able to be made to climb a column to lift a prefabricated wall into a predetermined position. The lifter comprises a first sleeve to surround the column. A saddle engages the wall. The saddle extends forwardly of the first sleeve and is pivotably mounted. A first lever is pivotably mounted on the first sleeve adjacent the saddle. There is a fulcrum point for the first lever. A second sleeve surrounds the column and is disposed above the first sleeve when the lifter is in its useful position. A second lever extends from the second sleeve to permit tilting of the second sleeve on the column. There is a link between the first and second sleeves, pivotably connected to each sleeve. The lifter is easy to use and to make and relatively cheap.
