The escalator comb plate is located at bothends of an escalator or moving walk, where the moving steps meet the fixedlanding portion. The escalator comb plate has teeth, which are aligned with therecess of the steps and are rounded in shape. Often they are provided in yellowallowing passengers to easier identify the transition line of the often greysteps and grey landing plate. A safety switch is also fitted behind the compplate to switch off the escalator in case anything gets stuck there. The teeth ofthe escalator comb plate can break off when small stones, screws or coins arecaught in between. Escalator comb plates sections are usually fitted with twoscrews and damaged ones can be easily replaced.
Good escalator comb plate:
The teeth will be cut off when it’s hitbetween the step, will not have the turnup broken teeth on the comb plate.
Bad escaaltor comb plate:
The borken turnup teeth will leave on thecomb plate, and it will hurt the people and step.
However, the safety device fitted on all escalatorsand moving walks is often not well maintained by the owner. The likelihood tofind a broken tooth on a high traffic escalator or moving walk is actually veryhigh. Escalators are usually serviced once a month, hence it can take some timeuntil a broken tooth is noted. Owners are also not always keen to replaceescalator comb plates with "only" one broken tooth due the continuousreplacement costs.
One or multiple broken teeth are serioushazards, especially for children hands and shoes. Hence, I would like to remindon the safe usage of escalators and moving walks:
The escalator comb plate is located at bothends of the exit entrance, to facilitate passenger transition and engage withsteps, pedals or automatic sidewalk tape. The ends are rounded and shaped tominimize the risk of foot clamping between steps, pedals or tape. Thesupporting structure shall be adjustable to ensure proper meshing and properstiffness.
The escalator comb plate is the safetyprotection device of the elevator. There is a micro switch behind the escalatorcomb plate.
One side of the escalator comb plate issupported on the front plate and the other side is used as the fixing surfaceof the comb tooth. Its horizontal Angle < 10 °.The structure of theescalator comb plate shall be adjustable to ensure that the meshing depth ofthe carding teeth is greater than 6 mm. It can be made of aluminum alloyprofiles or thick carbon steel plates.
The comb lamp is a part of an escalator andwalkway that gives light from under the foot of the passenger at the exit.Usually set at the end of the skirt board at the entrance and exit. Lightingshould be adequate and adequate. The lighting at the escalator comb plateshould be consistent with the lighting required in the area. The lighting atthe indoor or outdoor escalator and the exit of the automatic sidewalk shouldbe at least 50lx or 15lx respectively.
