A METHOD FOR A RESCUE OPERATION AND AN ELEVATOR SYSTEM

The invention relates to an elevator system comprising: at least a first (3) and a second elevator (13), the first elevator having a first elevator car (8), a first counterweight (4) and a first drive system (5), and the second elevator (13) having a second elevator car (8), a second counterweight (14) and a second drive system (14). To facilitate a simple and rapid rescue operation the elevator system comprises: a regenerative operation interface (22) in the first elevator (3) to provide electric power from the first elevator (3) to the second elevator (13), and a regenerative operation interface (22) in the second elevator (13) for receiving electric power from the first elevator (3) and for energizing the second drive system (16) to drive the second elevator car (18) to a rescue position.
