ABSTRACT:
An escalator is arranged such that a first special step having a movable footplate capable of rising and falling is combined with a second special step adjacent to the upstream side of the first special step and having a projectable and retractable lift mechanism. The projectable and retractable lift mechanism supports the movable footplate of the first special step in part of a plurality of running steps provided endlessly in a line. When mounting a wheelchair, the movable footplate runs along the inclined path area with the movable footplate supported at the same height as the second special step by operating the lift mechanism in the horizontal path area of the travel path. The movable footplate ensures a rearward footplate dimension sufficient to carry the wheelchair. Accordingly, the wheelstops for the front wheels of the wheelchair are made to project, thereby better defining the wheelchair carrying position and improving the safety and shortening the time taken when mounting and transporting a wheelchair.
