Cleaning Method Of Escalator Drive Chain


    The escalator is an open transportation machine that is driven by electricity and can carry a large number of passengers continuously in a certain direction. It has the characteristics of compact structure, safety and reliability, simple and convenient installation and maintenance. Therefore, it is widely used in places with large and concentrated passenger flows, such as stations, terminals, shopping malls, and so on. Pedestrians who walk on one end of the escalator will automatically be taken to the other end of the escalator. The steps will be kept horizontal all the way. There are handrails that move synchronously with the steps on both sides of the step for users to hold. The escalator can always walk in one direction, but most of them can control the walking direction according to the needs of time and flow of people. Asynchronous handrails and steps will seriously affect the normal, safe and reliable operation of the escalator, and there are certain hidden dangers.

    The hzqjchain Drive Chain manufacturer will tell you about the maintenance steps of the handrail Drive Chain.

    1) Open the lower pedal of the escalator, insert the maintenance box, and remove the protective cover;

    2) Remove 3-4 consecutive steps, move the unloading step part directly above the handrail drive chain, and cut off the power;
