ABSTRACT:
An elevator with a 4:1 cable guidance includes a drive unit and a first deflecting roller arranged at a carrier supported at one end on a first car guide rail and a first counterweight guide rail and at the other end on a second counterweight guide rail. The guide rails are connected with the shaft wall by means of yokes, whereby the vertical rail forces are conducted into the shaft pit. A drive bracket arranged at the carrier carries the drive unit and the drive pulley. A roller bracket arranged at the carrier carries the first deflecting roller. In addition, a first cable fixing point and a second cable fixing point for opposite ends of a cable are arranged at the carrier. The second deflecting roller is supported on a second car guide rail.
