ABSTRACT:
The escalator step has a frame made from metal, and a tread board of metal carried on the frame. The tread board is completely isolated from vibrations imparted to the frame by means of an elastomeric vibration damping material such as rubber which prevents the tread board from directly contacting the frame. The exposed riding surface of the tread board on which passengers stand is metal and is preferably cleated for safety purposes.
