Abstract
An escalator system with vertical step risers and side flanges includes a plurality of escalator steps, at least one varying length drive mechanism, a first decking, and a second decking. Each of the plurality of escalator steps includes an elongated step body, a first step mounted angled flange, and a second step mounted angled flange. The elongated step body transports passengers along the escalator path. The first step mounted angled flange and the second step mounted angled flange connect to form continuous barriers that prevent entrapment of objects between the moving steps and stationary panels. The at least one varying length drive mechanism prevents horizontal movement between each of the plurality of escalator steps traveling along the passenger side, thereby preventing entrapment of objects between adjacent steps. The first decking and the second decking partially cover the first step mounted angled flange and the second step mounted angled flange.
