ABSTRACT:
A pier (10) for supporting an object, such as a mobile home coach frame, above the ground generally comprises support (80) supporting pipe (70) in a vertical position and against downward movement, platform (30) having a sloped upper surface (43) supported by top end (71) of pipe (70), and wedge (50) supported by platform (30); wedge (50) having slanted bottom (53) and horizontal top surface (60) for supporting the load. The height of pier (10) can be adjusted by sliding wedge (50) up sloped surface (43). Gripping ridges (45,55) on slope (43) and slanted bottom (53) interact so that the wedge (50) may not slide down the slope (43). Platform (30) includes a plurality of receptacles (40) for receiving top end (71) of pipe (70) for supporting sloped surface (43) at various heights.
