  • This arrangement differs fundamentally from previously known tensioning devices in that, in the tensioning station, the conveyor cable is tensioned by the tensioning device with a variable tensioning force which is dependent on the loading condition of the cable car or the drag lift.
  • An advantage of the invention is that the station in which the basic tensioning force of the conveyor rope is to be kept constant for reasons of rope dimensioning (course of the rope tensioning forces, size and location of the occurrence of the largest and smallest rope tensioning forces) with a fixed drive or deflection sheave can be.
