Elevator parts manufacturers briefly describe the composition and operation of escalators

Escalators are one of the largest and most expensive machines used in people's daily lives, but they are also one of the simplest machines.

The escalator consists mainly of a ladder (variable slab conveyor) and handrails on both sides (deformed belt conveyor). The main components are step, traction chain and sprocket, guide rail system, main drive system (including motor, speed reducer, brake and intermediate drive link, etc.) drive spindle, ladder tensioning device, armrest system, comb plate, escalator skeleton and Electrical system, etc. The steps gradually form a step after the passengers move horizontally (convenient for the passengers to board the ladder); the steps near the entrance gradually disappear, and the steps are horizontally moved again. These movements are realized by walking the main and auxiliary wheels of the step along different step guides. The core component of the escalator is two chains that circulate around two pairs of gears. At the top of the escalator, there is a motor that drives the drive gear to rotate the chain. A typical escalator uses a 100 hp engine to turn the gears. Both the engine and the chain system are mounted in a truss, which is a metal structure that extends between two floors. Although the escalator is easy and convenient, the safety issue cannot be ignored. It is strictly carried out according to regulations when riding.
