Step Tracks

A series of tracks which support and guide the steps through both the exposed and return portions of step travel. The chain (leading) wheels and the trailing wheels have separate track systems. Changes in the vertical height between the chain wheel track and the trailing wheel track cause the steps to flatten out at both upper and lower end of the unit.
