The present invention belongs to the field of workflows and transport, more precisely to the field of devices for boarding passengers on aeroplanes. The invention relates to a lift for telescopic passenger stairs enabling disabled passengers with impaired mobility to board a plane and to telescopic aeroplane passenger stairs with the said lift.
This invention solves the problem of moving the lift regardless of the degree of extension of the telescopic staircase, with a moveable guide rail (4) installed into a lower staircase, which can travel to the top of an upper staircase if needed. The guide rail (4) in the lower part serves as a fixed guide rail for the lifting platform (3), onto which a passenger in a wheelchair is wheeled, wherein the platform (3) moves along the guide rail (4). When the platform (3) reaches the end of the guide rail (4), it is locked in place, after which the guide rail (4) itself then moves along the track of the upper part of the staircase, wherein it is connected to the guide rail (4) via wheels. The described movement is enabled by a system comprising an endless chain (46), guide rollers (44) and wheels (36, 47), a drive sprocket (45) and a drive, and the said guide rail (4).
