The very best platform normally has the motor assembly and the principle travel equipment, though The underside retains the return gear. These sections also anchor the ends in the escalator truss. Every platform also has a floor and a comb bearer. The floor plate gives a place for the travellers to stand in advance of they move on to the moving stairs, flush with the remainder of the flooring and therefore are detachable to allow straightforward engineer entry, whilst the comb bearer sits in between the stationary floor plate as well as the shifting step, so named with the cleats on its edge which mesh with the matching cleats on Every single stage (and resemble a comb).
