Abstract (en)
[origin: EP1864938A1] Elevator arrangement (1) comprises a shaft (10) having a cross-section which has a widened section (E) in an approach section (A) to reduce surge pressure built up in the approach section when a counterweight (12) passes the elevator cabin (11). Preferred Features: The widened section is in the form of one or more local stretches on the shaft. The cross-section of the shaft is larger in the region of the widened section than in the remaining region of the shaft.
