Escalators can be installed in parallel or diagonally depending on location layout. In both cases, the ascent and descent units may be side by side or separated at some distance from each other. In some cases, a third escalator can be installed in a multi-level, parallel arrangement. The units have flexibility of use in terms of heavy traffic.

The following factors are important for positioning the escalators at the location:

a. Building structure

b. Traffic flow direction

c.Traffic volume

d. Field of application (commercial sector, public transport)

e. Special customer requests

Escalators typically have four configuration options:

1. Single Unit

2. Crisscross

3. Parallel

4.  Multiple parallel

SINGLE UNIT CONFIGURATION

A single unit connects two floors. It is generally used when traffic flows in one direction only. The direction of the escalator can be adjusted according to traffic flow, for example, in a business and event center or cinemas.  It can flow upwards in the morning and downwards in the evening.  It is also often placed beside a staircase.

CRISSCROSS CONFIGURATION

Minimizes structural space requirements by "stacking" escalators that go in one direction, frequently used in department stores or shopping centers. It allows passengers to see floors and products comfortably, and also shortens the traffic flow time between escalators.

PARALLEL CONFIGURATION

The parallel layout has good traffic capability to allow passengers to be transported in a minimum amount of time.

When the escalators are installed on top of each other, space is saved and the floor space is utilized in the most effective way. There is no need for architectural changes to the building.

Up and down escalators "side by side or separated by a distance," are often used in undergrounds and multilevel cinemas.

MULTIPLE PARALLEL CONFIGURATION

The multiple parallel configuration is generally used in workplaces with high traffic volume and in places where public transportation is very dense. The direction of traffic flow can be arranged in the same and opposite direction according to the traffic density for parallel units.

Notes:

1. A combination of the four main configurations is possible according to architectual building designs and site preferences.
2. It may also be necessary to provide an elevator lift adjacent to an escalator for wheelchairs and disabled persons.
