The Cylinder Driven High Dog Indexer consists of four patented Hydraulic cylinders in series on each side of the track pushing a single High Dog Carriage. The Chain Driven High Dog Indexer consists of a hydraulic motor and gear reducer with a sprocket on each side of the track, each pushing a single High Dog Carriage. Both of these options can push up to 100,000 pounds on a fully loaded railcar and can be single direction or forward and reversing.
