Easy to edit 14 31 00 Escalators construction specification to specify electrically operated escalators with related equipment and enclosures.
An escalator is defined as a power-driven set of stairs arranged like an endless belt that ascends or descends continuously.
Escalators are often used in pairs that operate in opposite directions and often in conjunction with fixed stairs and elevators. Escalators can be difficult for people with physical disabilities and those with luggage or strollers to access, dictating the need for an elevator as well.
Escalators are available with reversing switches to allow for adaptation to varying traffic loads.
