Escalators and Stairs at Metro Station
Escalators
(a)Escalators shall be provided at all Stations to assist vertical User traffic flow between street level, concourse and platforms to meet the requirement of the Key Performance Indicators and NFPA-130.
(b)Capacity and travel speed of escalators shall be computed as under:
(i)Capacity – 60 to 90 persons per minute (minimum)
(ii)Travel Speed – 14.63 m/minute (vertical component of travel speed)
©Escalators shall be used as stairways in stationary position during an Emergency for Station evacuation. All escalators shall be of a standard pattern, two lanes wide, having a minimum width of 1000 mm with a width at hip height of 1200 mm. They shall have four (4) flat treads at entry and exit and be equipped with double safety brushes on either side.
(d)Escalators shall be reversible, monitoring and control of the operation being through the system of SMS.
(e)Escalators shall be designed for continuous operation in either direction for a period of not less than 20 hours per day, seven days per week, at temperatures varying between 5°C and 46°C.
(f)Materials of construction for escalators exposed to high ambient temperatures and dusty and dirty conditions shall be suitable for these aggressive conditions.
(g)Escalators shall comply with BS-EN 115. They shall be suitable for service as public service escalators /passenger conveyors. The angle inclination of the escalators shall be not more than 30° to the horizontal with two tread band speeds of 0.5 and 0.65 m/s. During periods of no occupancy, the speed shall automatically reduce to 0.2 m/s and come to halt if not occupied for 5 minutes.
(h)Access shall be provided to the escalator underside for cleaning purposes.
(i)Operation of escalators (starting and stopping) shall be controlled from upper or lower level and from the Station Control Room.
(j)Escalators shall be located along the normal and direct path of User circulation and be easily identifiable.
(k)Escalators shall be so designed that routine operation and maintenance can be performed with minimum disruption to Station functioning.
(l)Escalators shall conform to BS EN 115: Safety rules for the construction and installation of escalators and passenger conveyors.
