摘要： An elevator assembly with a rack-and-pinion drive including a tower and an elevator. The elevator assembly is designed to allow the autonomous inverse assembly of the tower on a shaft and/or a gallery during excavation processes. The elevator assembly descends along a suspended tower as far as a bottom end of the tower to convey mast sections to be assembled under the tower. The mast sections to be assembled are positioned for fishplating thereof, one by one, by means of a movable deck of the elevator assembly. A inverse assembly method, a docking method, and a method for dismantling the elevator assembly are also provided.
