One alternative to the classic vertical elevator is the inclined elevator. An inclined elevator is a practical option for certain sites, e.g. slopes, railway station connections and special architectural circumstances. The customer profits from the technology and experience of vertical elevator construction. European directives define an inclined elevator as a "conveyance drawn by chains or cables used to transport people or people and loads that is mounted between guide rails that have a maximum angle of between 15° and 75° to the perpendicular, without limitation of the travel path."
