- a winding area 92 on the brake side is attached or formed on each of the two ends of the shaft 93 in a rotationally fixed manner; the two winding-up areas 92 on the brake side rotate with the shaft 93 and can therefore wind up or unwind their associated actuating element 80 on the brake side in accordance with the respective direction of rotation of the shaft 93 .
- the two brake-side winding regions 92 also rotate and wind their associated brake-side actuating elements 80 up or down, which causes the front frame part 32 of the magnetic track brake to be raised or lowered 20 is coming.
- the front reduction deflection device 60 and the rear reduction deflection device 60a can also be identical in the second exemplary embodiment according to FIG. 3; the above statements in connection with the front reduction deflection device 60 can therefore apply correspondingly to the further rear reduction deflection device 60a.
- FIG. 4 shows an exemplary embodiment of a drive device 40 that can be used in the traversing devices 10 according to FIGS.
- the drive device 40 comprises a motor 41, which is preferably an electric motor or an electrohydraulic motor.

- the function of the tension spring 130 is to exert a tensile force Fz on the anchor element 110 in the direction of the sleeve end 122 or the drive device 40 .
- the weight of the magnetic rail brake 10 pulls the anchor element 110 onto the sleeve stop 121 because the tensile force Fz of the tension spring 130 cannot hold the magnetic rail brake 20.

It can be seen that the control sleeve 120 relative to the housing 125 by the distance dX to the left. Since the rails 30 do not yet generate any counterforce, the anchor element 110 is still pulled onto the sleeve-side stop 121 of the control sleeve 120; the relative position of the anchor element 110 relative to the control sleeve 120 is therefore still unchanged.
- Figure 7 shows the spring device 100 according to Figure 5 after the magnetic rail brake 20 has been placed on the rails 30. Since the rails 30 now generate a counterforce and define the position of the magnetic rail brake 20, the spring device 100 can now prevent the drive-side actuating element 70 or the or the brake-side adjusting elements 80 if the drive device 40 moves the control sleeve 120 further to the left or further in the direction of the lowered position than the lowered position would require. It can be seen in FIG.
