For lovers of vintage machinery and equipment, this grahics intense catalog is a must have for your collection.
In 1913, Haiss began making elevator loaders powered by gasoline engines. These machines could load sand or gravel direct from the bank, and crushed stone or other materials from stockpiles. In 1918, the company originated power crowding (wheel drive) so that the loader could propel itself slowly into the bank. At the same time, Haiss patented a force-feeding device (spiral propellers) that fitted in front of the machine. This enabled material to be collected from a wide path, reaching outside the machine width, and maximizing the load in each elevator bucket.
