Types of escalators

Mechanically, the escalator is a simple yet attractive vertical transportation system. Escalator consists of two words: stairs (Escala) and elevator (Elevator); But these two words are combined with each other and are generally known by the Latin name "Escalators". Escalator is defined in Cambridge University Online Dictionary website as: "A set of stairs that go up or down with electric power and people can stand on it and move from one level of a building to another."< br>

The escalators are divided into the following three categories in terms of where they are installed and where they work:

Commercial escalators are usually used for buildings whose total working hours are less than 12 hours a day and there is no sudden crowd traffic and the amount of traffic in that place is almost uniform. These types of stairs are used in multi-story private stores, hotels with more than one lobby, etc.

This type of escalator is usually used in buildings that are used by the public most of the time. This type of semi-commercial escalators are usually installed outside the building, that is, they are used in pedestrian bridges, remote subway stations, etc.

Non-commercial escalators are used in places where there is a lot of traffic, including train stations and passenger terminals. These stairs are the heaviest in terms of weight and the most expensive type of escalators.

First: Escalator with single arrangement In this type of arrangement, there is a short horizontal path between the stairs that passengers must walk through. This path can usually create motivation for customers and this leads to better income for sellers. Second: parallel escalator This type of arrangement requires more space and there must be enough foot space between the escalators. In parallel arrangement, people reach the upper floors in the shortest possible time. If the length of the building is high, using this type of arrangement is recommended. Usually, this type of escalator is more efficient and more expensive. Of course, this type of escalator includes different types such as parallel spiral and multiple parallel escalators, each of which can be installed according to the location and taste of people. Third: Cross or cross escalator Cross arrangement is mostly for office buildings, large stores, etc. and is the most common type of escalator arrangement. Fourth: curved escalator Installing this type of escalator usually saves space and increases the beauty of the building's architecture. Fifth: wheelchair accessible escalator This type of escalator has a feature that when used by people in wheelchairs, three steps are aligned with each other at the same time and take the wheelchair along with the person sitting on it to the desired floor. Sixth: belt escalator This type of escalator is the newest type of escalator, which is also known as moving corridors. This type can be installed in flat environments to minimize walking, and flat and non-flat spaces are connected and accessible with this type of escalator.

Escalator design depends on several factors: Traffic patterns The location of the building Increasing the vertical and horizontal distance Building infrastructure Safety considerations carrying capacity Also, the following points should be considered in the design of escalators: It can move in both up and down directions. Using a sensor for the presence of passengers or an electronic eye to reduce energy consumption The presence of a red emergency button on the right side of the entrance and exit of the escalator for emergency stop when feeling in danger Paying attention to the vertical and horizontal distance where the escalator is supposed to be installed in order to calculate the slope of the escalator and its actual length The strength of the foundation of the building to support the weight of the components along with the weight of the passengers of the escalator Paying attention to the type of use of the escalator and where the escalator is used and for what purpose is helpful in the design. Pay attention to the amount of traffic and traffic patterns in the place of installation. Safety considerations such as installing an escalator in a fire-proof isolated place, placing air conditioning valves in the engine and gear installation compartment to control the temperature increase, etc. Coordination of the escalator system with the decoration of the installation site and the use of a wide and diverse range of tastes and colors for the handles and guards of the escalators. Choosing the place to install the escalator should be in such a way that the majority of people can see it and not disturb the visibility of the store's products It is very important to pay attention to the moving capacity of the escalator because it should be calculated according to the peak traffic demand. This tip is very effective in places that have a sudden increase in traffic Placing the staircase and wheelchair lift in the vicinity of the escalator
