1. Elevator structure:

The escalator consists of a ladder and handrails on both sides. Its main components include steps, traction chains, and sprockets, guide rail systems, main drive system drive spindles, ladder tensioners, handrail systems, combs, escalator frames, and electrical systems. After the steps are horizontally moved at the entrance of the passenger, the steps gradually form a step; the steps near the entrance gradually disappear, and the steps are again horizontally moved. These movements are realized by walking the main and auxiliary wheels of the step along different step guides. Many Escalator Company are designed this way.

2. The principle of the escalator:

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.

Unlike a plane in which the conveyor moves, the chain moves a set of steps. The most interesting part of the escalator is how these steps move. The steps are always level as the chain moves. At the top and bottom of the escalator, the steps fold over each other to form a platform. This makes the upper and lower escalators easier.

Each step on the escalator has two sets of wheels that rotate along two separate tracks. The upper unit (the wheel near the top of the step) is connected to the rotating chain and pulled by the drive gear at the top of the escalator. The wheels of the other groups simply slide along the track, following the first set of wheels.

The two tracks are spaced apart from one another so that each step is level. At the top and bottom of the escalator, the track is horizontal so that the steps are flattened. There is a series of grooves inside each step to connect the two steps before and after the flattening.

In addition to rotating the main chainring, the electric motor in the escalator can also move the handrail. The armrest is just a rubber conveyor belt that circulates around a series of wheels. The conveyor belt is precisely configured to move exactly the same speed as the step, allowing the rider to feel smooth.

The escalator system does not raise people to buy dozens of floors like an elevator but is ideal for providing short-distance transportation. This is because of the high load rate of the escalator. After the elevator is full, it must wait for it to reach the designated floor and return to the other person to get on the elevator. On the escalator, as long as one person reaches the upper level, it will make room for others.

3. What is the width of the escalator:

Step width: 600 mm, 800 mm, 1000 mm. The escalator is divided into two angles of 30 degrees and 35 degrees. It is now common to install an elevator with a one-meter-wide ladder. The outer diameter of the escalator is 1.55 meters. The specified size of the two sets is 3.6 meters (3.3). The meter can be installed. If the single unit is larger than 1.6 meters, the calculation formula of the span of the escalator is the front of the escalator plus the middle size plus the middle size. (The intermediate size of the escalator should be the trigonometric function tan30∠=0.577 and tan35∠=0.700. The escalator with a height of 4 meters and a 35-degree angle is about 4.8 meters (the size of each elevator manufacturer is not the same but the size difference is small) plus (4.0/0.7=5.71)=11.4 meters. Thus, the width of the 4 m escalator is 3.6 meters and the span is 11.4 meters.
