A lift has a lift cage movable in a lift shaft and is connected with a counterweight by means of at least one support means. The lift cage or counterweight moves by means of at least one drive means separate from the support means. One end of the drive means engages the upper end of the counterweight, is guided by way of a drive pulley and by way of a deflecting roller, and engages at its other end with the lower end of the counterweight. A drive unit drives the drive pulley. The drive means consists of a drive part and a tension part of different characteristics, wherein the drive and tension parts are connected by means of a drive means connection.
