    Foreword Foreword Dear Reader, these Operating Instructions provide all information neces- sary to safely operate the Back-in-Box-Lifts K70, K90 and K90 ACTIVE. The Back-in-Box-Lifts are designed and constructed in ac- cordance with state of the art technology and recognised safety standards. Persons and materials can however be endangered, as not all danger areas can be eliminated if the functional capability is to be maintained.

    AMF- Bruns GmbH & Co. KG. The costs of such work will not be accepted by AMF-Bruns without prior agreement. Danger Zone The danger zone is any area on, below or within the range of movement of the platform, as well as around the drive and carrier system, in which persons are exposed to the risk of injury or damage to health.

  • Page 12: Safety Devices

    A door contact switch is fitted to the vehicle door, above the Back-in-Box-Lift. It disables all functions of the Back-in-Box-Lift when the door is closed. This prevents the Back-in-Box-Lift from being operated inadvertently or by unauthorised persons. Page 12 of 100 Back-in-Box-Lift K70 / K90 / K90 ACTIVE...

  • Page 17: Platform

    The platforms on the Back-in-Box-Lifts K70, K90 and K90 ACTIVE are of differing design: With the K70 and K90, the wheelchair is pushed onto the platform in the direction of the door of the vehicle, below which the lift is installed (see Figure 3).
  • Page 18 (see Fig- ure 5 and Figure 6). Transfer plate Figure 5: Back-in-Box Lifts K70 and K90, Interior Floor Level Transfer plate Figure 6: Back-in-Box-Lift K90 ACTIVE, Interior Floor Level Guards are provided on all other sides of the platform to prevent the wheelchair from rolling off the platform (see Figure 5 and Figure 6).
  • Page 19 Description On the K70 and K90, one of the platform’s two side guards is optionally shortened to extend roughly half way along that side. This provides side access to the platform, mak- ing it easier for the passenger to roll on and off the plat- form when there is limited space available outside the ve- hicle (see Figure 7).

  • Page 20: Mechanics And Hydraulics With Carrier Arms

    The transfer plate automatically folds down when the platform is retracted. On the K70 and K90 there are two carrier arms on both the left- and right-hand sides of the platform (see Figure 10).

    A rating plate, which contains the fundamental data, is at- tached to the Back-in-Box-Lift (see Figure 14). The rating plate on the K70 and K90 is located on the right-hand side of the platform. The rating plate on the K90 ACTIVE is lo- cated on the strut of the internal carriage, behind the transfer plate.
