WHAT IS ESCALATOR?
An escalator is a moving staircase – a conveyor transport device for carrying people between floors of a building.
designed on an incline of 27.3, 30, 35 degrees.
If the height is more than 6m than
incline of 27.3 should be given
The speed of the escalator, shall not be more than 0.63 m/s for 30o angle of incline
and 0.50 m/s for 35o angle of incline.

19. LIFT,ESCALATOR AND MOVING WALKS
TYPES OF ESCALATOR:
MULTI PARALLEL
PARALLEL: These type of escalator go up and down simultaneously.
CRISS-CROSS: They stacks the escalators that go in single direction and reduces structural space requirement.

20. LIFT,ESCALATOR AND MOVING WALKS
TYPES OF ESCALATOR:
UP” ESCALATOR NEXT TO STAIRCASE : It
is preferred that staircases be located adjacent to the escalator if the escalator is the primary means of transport between
floors.
SPIRAL TYPE ESCALATORS: These are
used to enhance the architectural beauty and to save the space.
