2: upper or lower or lower platforms
In all escalators, regardless of their type or brand, the first part that we encounter when riding the escalator are the platforms, which can be seen horizontally and with steel caps. They are specially removed and slide out of the escalator skeleton. Under the cover and inside the upper platform, the escalator motor, escalator control panel, three-phase panel and other equipment can be seen. The last part of this platform which is near The most moving part of the steps is called shoulder plane. These shoulder plates are movable and connected to motion sensors so that if something gets stuck between the steps or if the adjustment of the steps is messed up and hits the edge, the pushed back edge will trigger the sensors and cause it to turn off. escalator motor to prevent damage.
2: Gearbox
As mentioned, there are various parts inside the upper platform, one of the most important of which is the gearbox motor. The escalator motor is designed and installed horizontally and vertically in the stairs. These motors are coupled with There are gearboxes that convert electrical power into mechanical power and transfer it to the step of the escalator through the chain of the escalator and with the help of a large gear, and this action causes the escalator to move in the desired direction.
2: Brake system
In escalators, the main brake is responsible for keeping the stairs completely. When the stairs start to move, the jaws move away from the motor axis. At the same time, electricity enters the motor and causes it to move. The power cut inside the motor simultaneously closes the jaws and causes the main axis to stop and as a result the step.
2: The steering wheel
Like elevators, escalators have a part called control panel, but it is much less complicated than elevators. And its task is to control the operation of the switches, and to plan the stairs. In escalators, there are many devices for safety and to prevent incorrect operation of parts.
1. Step
The steps are the psychological stairs that passengers stand on and move to the other part of the stairs. Usually, the width of the steps in the escalators is 80 cm and 100 cm wide, but the width of the ramp or moving sidewalks reach up to 1400 mm and are applicable.
2: Stay chains
This part is one of the important parts in escalators. In most cases, it is made of steel and its task is to transfer the power of the motor to the steps and move the stairs. Most of the escalator chains are designed to reduce friction and They need lubrication to increase their lifespan.
