In the case of an installation, for example a lift installation (30), with a belt-like drive means (32), which is driven by a drive pulley (35.1) and has at least one electrically conductive element for transmission of signals and/or energy, which extends in the longitudinal direction of the drive means, wherein a contact means (40.2) is provided, which produces contact with the at least one electrically conductive element in a region of the drive means (32) moving in operation of the installation, the force transmission from the drive pulley (35.1) to the belt-like drive means (32) is carried out by friction couple..
