I am seeking information and expertise from an escalator expert who has knowledge of speed changes on escalators whether caused by actual speed changes or lack of coordination between handrails and stairs. Harold M. Saalfeld

pulsing of steps or handrail can be caused by drive chain or drive sprocket wear, or a deteriorating connection between the sprocket and driving motor
