  • the outgoing rope sections go in the preferred embodiment of the rope arrangement as a continuous rope into one another and lie over a deflection roller 9, which counter to the Restoring force of the cable tensioning device 7 is displaceable.
  • the pulley 9 can preferably with a horizontal axis of rotation while maintaining the parallel vertically spaced cable sections SA may be upright or after deflection of the vertically spaced rope sections SA in horizontal spaced rope sections lying with a vertical axis alignment.
  • the Deflection roller can be moved along a rod, a backdrop etc. run with little friction.
  • the rope sections SA with the pulley 9 are , advantageously protected in a clad channel.
  • the wave can face the median plane of the channel be slightly offset laterally so that the rope sections running out of the roller elements in this from the beginning Middle level.
  • the Bridge 8 contains a front vertical support STV and a rear vertical support STH, which are connected by a bridge.
  • the Bridge in particular comprises a longitudinal strut TH and a drive frame AR, which is the complete drive unit consisting of roller elements, shaft and Contains braking device.
  • the drive frame preferably also includes still a transverse traverse, which the laterally spaced deflection devices and inlet guides.
  • Rope sections are advantageous SA, deflection roller 9 and rope tensioning device 7 in the hollow longitudinal spar, which can also be designed as a U-profile.
  • the different Modules are advantageously designed to be plugged into one another.
  • the connection the rear vertical support with the horizontal longitudinal beam TH can advantageously by oblique struts STS, which are outlined in the Example curved, be stiff.
  • a footboard 121 for support can be attached to the sloping struts.
  • the vertical supports STV and STH are designed to be stable with cross struts QV and QH.
  • the element structure from detachably connected components STV, STH, TH and AR enables a particularly small volume during transport and storage.
  • the drive unit contains the most important moving mechanical elements and can be manufactured and tested separately. The variability for different movement simulations using different movement modules remains intact due to the construction of detachably connected elements.
  • the drive unit is formed by a housing covered with an upper shell GHO and a lower shell GHU.
  • the Wind turbine with an existing housing can also be outside the housing shell GHU lie, which then preferably an indentation after has inside as a receiving space for the braking device.
  • the roller elements can also on separate spaced axes in the Middle plane of the device can be arranged, the distance of the axes from each other is small compared to the lateral distance BS of the rope inlets.
  • the coupling to the braking device then takes place via additional gear elements.
  • the braking device can also with coaxially arranged roller elements rotate on a separate shaft, with a speed ratio between Roller elements and braking device is possible.
  • the in Fig. 8 and Fig. 9 outlined coaxial arrangement of roller elements and braking device but particularly advantageous due to its simple structure.
