  • the longitudinal section can be attached to the support on the one hand and to the console on the other hand. This means that no additional component is required to support the carrier on the console.
  • the guide rail can be a hollow rail.
  • Such a guide rail is particularly stiff and stable.
  • the longitudinal section can be an end section of the guide rail.
  • the carrier can be arranged at an upper end of the guide rail when the device is in the assembled state.
  • the carrier can rest on the upper end of the guide rail.
  • the console can be anchored in a floor and/or on a side wall directly at the floor of one of the floors when the device is in the assembled state.
  • the console can be used directly and/or indirectly, i.e. H. be connected to the floor via at least one connecting part, for example in the form of a support or a plate.
  • the floor can be, for example, the floor of a top floor. This enables a particularly stable attachment of the console to the side wall.
  • the carrier can rest on an upper end of the support when the device is in the assembled state.
  • the upper end of the support can touch an underside of the carrier.
  • the underside of the carrier can also have at least one connecting part, for example in the form of a connecting part arranged between the carrier and the support Intermediate plate, connected to the upper end of the support.
  • the connecting part can be attached to the carrier and/or the support in the assembled state of the device, for example screwed and/or welded to it.
  • the connecting part can also include a fastening section for additionally fastening the drive motor to the connecting part. This enables a statically determined storage of the drive motor at two storage points, namely the holder on the carrier and the fastening section.

Similar to the support, the additional support can be connected to the carrier on the one hand and to the console on the other hand when the device is in the assembled state. When the device is in the assembled state, the additional support can extend horizontally at least in sections between the support and the side wall and/or vertically at least in sections between the carrier and the console. Because several, i.e. two or more than two, supports are used for support, the supports can each be made lighter and/or simpler than if only a single support is used. This also makes the support safer.
  • the device may further comprise a plate-like wall element which is designed such that, in the assembled state of the device, it extends at least partially between the support and the side wall.
  • the wall element can be designed such that, in the assembled state of the device, it covers at least 50%, preferably at least 75%, of a surface that is delimited in the horizontal direction by the support and the side wall and in the vertical direction by the carrier and the console.

  • a width of a section of the wall element extending between the support and the side wall in the horizontal direction can be at least 50%, preferably at least 75% of a horizontal distance between the support and the side wall. This can be advantageous for weight and/or stability reasons.
  • the wall element can have a plurality of recesses, the respective width of which can be at least 25%, preferably at least 50% of a width of the wall element and/or the respective height of which can be at least 10%, preferably at least 25% of a height of the wall element. This allows the weight of the wall element to be significantly reduced.
  • the wall element can be a sheet metal part. This enables cost-effective production of the wall element.
  • the additional support can be formed by the wall element. This means that, in addition to the wall element, no further component is required to additionally support the carrier on the console.
  • the end of the support attached to the side wall and/or the ceiling can be attached to the side wall and/or the ceiling via at least one vibration-damping intermediate piece.
  • Such an intermediate piece can be or include a rubber part, for example. In this way, undesirable vibrations and/or noises during operation of the drive motor can be noticeably reduced or avoided.
  • the supports of different devices can be attached to the same side wall of the shaft when the system is assembled.

  • the supports in the assembled state of the system, can be connected to one another to form a frame at their sections protruding into the shaft via at least one connecting part.
  • the connecting part can be plate-shaped or carrier-shaped, for example. This means that the rigidity of the beams can be significantly increased with little design effort compared to designs in which the beams are not connected to one another to form a frame.
  • the consoles can be connected to one another in the assembled state of the system via, for example, a plate-shaped or carrier-shaped connecting part.
  • the consoles can be attached to the side wall via the (common) connecting part.
