From the most basic function, the escalator is a simply modified conveyor belt. Two rotating chainrings drag a set of steps with a constant cycle and carry many people over short distances at a steady speed. In this article, we'll look at the internals of an escalator and see exactly how the pieces fit together. Although its principles are very simple, the system that keeps all the steps in perfect sync is truly amazing.

The core components of an escalator are two chains that rotate in cycles around two pairs of gears. At the top of the escalator, the motor drives the drive gear to turn the chainring. A typical escalator uses a 100-horsepower engine to turn the gears. The engine and chain system are mounted in a frame, which refers to a metal structure that extends between two layers. Unlike conveyor belts that move on a flat surface, chain links move on a series of steps. The most interesting thing about Huizhou Elevator Installation Escalator is the way these steps move. The steps remain level as the chain moves. At the top and bottom of the escalator, the steps are folded to form a platform. This makes getting up and down the escalator easier. An escalator is a transportation device with circulating steps that are used to transport passengers with a continuous upward or downward slope. Looking straight at it, it looks like a moving staircase accompanied by a moving handrail. The rotation of the escalator is not complicated, it is two circulating special chains that move on the low-speed sprocket driven by the reducer, and the pedals are hinged at the corresponding positions. The technical feature of the escalator is that the height of the pedals is maintained in the used part, which is controlled by small wheels on levers under the pedals that run on the control track. To ensure safety, when the special chain breaks, the escalator can automatically stop and get stuck on the safety device without slipping off. Each step of the escalator has a safety barrier to prevent passengers' feet from entering the movement area, and a safety device comb shovel is located at the end of the escalator. The pedals and chain are hinged, but there are small wheels at the ends of levers fixed to the ends of the pedals that run in guide slots on the sides to keep the pedals level. But when turned down, all the pedals are flat.
