A lift installation with a lift shaft is disclosed. The lift installation includes a counterweight and a lift cage. The counterweight and lift cage are arranged so that they are movable along a substantially rectilinear guide track. The lift cage is connected by way of support means with the counterweight, so that on movement of the lift cage, the counterweight executes an opposite movement, and the lift cage moves past the counterweight in a proximity region (A) in the lift shaft. In the proximity region (A) an enlargement (E) of the cross-section (Q) of the lift shaft is provided in order to reduce a pressure shock which builds up in the proximity region (A) when the lift cage moves past the counterweight.
