A conveyor for moving people is an automatic device that is used to move people in industrial and construction environments. This device saves time and money and helps people to go to their workplace or destination more quickly and safely. People moving conveyors are usually used in large and crowded spaces such as airports, train and subway stations, tall buildings and other public places. This device reduces people’s fatigue and stress and helps improve their quality of life.

What is an escalator? Escalator

Today, escalators are used as a means of transportation to move between two floors or two levels with a large height difference.

The main use of escalators is in public places with high traffic such as metro stations, large shopping centers, airports and high-traffic buildings.

The maximum capacity of modern escalators in terms of height is 18 meters.

Considering the standard height difference of both floors, which is 3.5 meters,
Each escalator can cover up to 5 floors.

The displacement rate or speed of modern escalators is 36 meters per minute.

The biggest escalators can move up to 6000 passengers in one hour.

The first escalator was produced in the United States in 1891.

This escalator was used in the form of a moving belt with a 25 degree inclination angle to move passengers.

After that, a more advanced version of this escalator was created in Paris in 1900.

A little later, in order to improve efficiency, engineers made changes in the appearance and operation of the escalator.

Perhaps the first and most important change is changing the angle of the escalator from 25 to 30 degrees.

Escalator security

Another important issue about the types of escalators is their safety.

Escalators are designed so that they can be stopped in case of any accident or critical situation.

If the chain that provides the necessary force to move the escalator breaks suddenly,
Due to the force that is suddenly released, the system is locked and the escalator stops.

The second method is to use a safety switch.

If the handrail is broken or loose, the escalator can be turned off immediately with the help of a safety switch.

Types of escalators

According to the use of the building, the type of use, the required space and other things, there are different types of escalators
A specific model of escalators is used in each building.

In the following, we are going to introduce the types of escalators.


Parallel Escalator

In this type, two rows of escalators are placed next to each other;

From one row, passengers go from the upper floor to the lower floor, and vice versa from the other row.

This type of escalator takes up a lot of space and its efficiency is lower than other types of escalators.

On the other hand, they are more expensive.

One of the advantages of parallel escalators is that passengers can easily find their location on each floor by following the movement pattern.

This type is usually used mostly in stores and subway stations.

Horizontal Escalator

Basically, the angle of inclination of these escalators is very limited and they are not used for climbing.

The movement of this type of escalator is horizontal;
This means that people can move with their belongings through this model of escalators.

Basically, these escalators are used as a bridge between two points.

Curved Escalator

The curved escalator is not much different from the spiral escalator.

The only difference is that the height and rotation of the stairs in the curved escalator is much less than the spiral escalator.

Basically, the use of this type of escalators does not have many technical or construction reasons, and they are mostly used for aesthetic reasons.

Basically, the speed or rate of movement of these escalators is lower than other models.

Due to their beauty, these types of escalators are used in large cinema halls, luxury hotels and tourist places.

Advantages and disadvantages of escalators

Each type of escalator, like any other device, has its own advantages and disadvantages.

Advantages of escalators:

Less expensive than the elevator
Occupying less space
Large capacity and suitable for crowded places

Disadvantages of escalators:

The inability to use escalators for the disabled
Possible dangers due to clothes or equipment getting stuck between the stairs
