Embodiment Construction

[0029] figure 1 An escalator 10 is shown. As should become apparent from the ensuing description, the invention is applicable to other passenger conveyor systems, such as moving walkways. The escalator 10 generally includes a truss 12 extending between a lower station 14 and an upper station 16 . A plurality of successively connected steps or treads 18 are connected to the step chain 20 and travel through a closed-loop path within the truss 12 . The pair of rails 22 includes a travel handrail 24 . A drive machine 26 or drive system is typically located in a machine space 28 below the upper landing 16; however, an additional machine space 28' can be located below the lower landing 14. Drive machine 26 is configured to drive treadle 18 and / or handrail 24 through step chain 20 . Drive machine 26 operates under normal operating conditions to move pedal 18 at a desired speed in a chosen direction.
