CA 2355806

The wall crane is used to raise a wall from a horizontal to a vertical position. The crane has a base, a telescopic post pivotally connected to the base and a pulley connected adjacent to the top of the post. A hook is used to connect the crane to the wall and a cable extends from the hook, over the pulley and terminates at a winch. By reeling the hook toward the winch, the wall is raised. A catch is connected to the post and engages the wall when it has been raised to a vertical position to prevent the wall from toppling over backward away from the crane.
