Article 6- Escalator Installation ArrangementDue to the fact that escalators are considered as the main element for even distribution of passengers among the floors of any building, the suitable arrangement of them in the space of the building is of utmost importance. The different type of installation arrangement are as follows and can be chosen based on the customer requirements:
Single Escalator Arrangement (One-way Traffic Flow)
This type of escalator arrangement is used in small buildings and commercial centers where there is insufficient space to install two escalator beside each other to provide two-way movement or where travel in a one direction is intended. In this arrangement, if the escalator is located in the center, outside cladding would be required on both sides. However, if the escalator is installed against a wall, outside cladding will only be needed for one side.
Parallel/Interrupted Arrangement (Two-way Traffic Flow)
Using this type of arrangement is a bit more difficult for the passengers because they must travel a comparatively farther distances on foot in order to reach a higher or lower floor. In the interrupted arrangement, passengers have to travel a distance and pass strategic locations, which would in turn increase the number of visits to the mentioned locations. With this type of arrangement, two escalators at the same level can be operated in the same direction during traffic peak times.
This type of arrangement is used in spaces where there is more available width. Also, passenger flow is continuous and it causes reduced crowding at landings. The scissor arrangement is modern and attractive with a high level of efficiency
This type of arrangement has a unique advantage, in that by adjusting the escalator’s direction of movement, it is possible to operate the escalator in both continuous and interrupted arrangement. The arrangement’s disadvantage, especially in commercial centers, is blocking the view on the other side of the void.
