Abstract
An elevator installation with an elevator shaft and an elevator car which is connected with a counterweight such that on movement of the elevator car the counterweight executes an opposite movement and the elevator car moves past the counterweight in a proximity region in the elevator shaft. Provided in the proximity region is an enlargement of the cross-section of the elevator shaft so as to reduce a pressure shock which builds up in the proximity region when the elevator car moves past the counterweight. Noise and vibrations can thereby be prevented.
