Abstract
A stacker for moving stone or other such material to the top of a pile by use of an endless belt conveyor. A long section of conveyor is rigged with converging suspension cables along its length to enable lifting the conveyor from a single point. With one end anchored and lifting near the center, the conveyor loading simulates static conditions as the other end is lifted above the discharge point. The central lift point is located at the top of a single mast which is leaned toward the anchored end of the conveyor. The combination of the angled mast and suspended conveyor section results in vector forces which give the assembly superior balance and stability and yields a conveyor support structure which is less costly and much lighter than previous designs.
