  • the control of the pulling force is, as already described above, taken over by driven by an internal combustion engine cable drums from the winch driver. He must be aware of the given towing speed, climb speed, rope slack, current attitude, wind speed, wind direction, communication with the pilot, as well as sudden gusts, unexpected force peaks and dangerous pilot oversteer maneuvers.
  • the towing winch has a tension indicator.
  • the tensile force can be detected by means of a strain gauge, which is arranged between a fixed stop of the towing winch and its Switzerlandkraftbegrenzer observed.

  • the support is basically pivotable about its pivot point, however, the actually occurring in operation deflection of the lever arm forms a negligible size. As a result, unwanted repercussions are excluded in a sudden change in the cable pull on the rope length.
  • the lever arm is biased by means of the actuating means against the sensor so that only changes in the biasing force due to the tensile load of the towing rope are detected.
  • a negative bias can be set as the output, so that even high forces do not lead to a lifting of the lever arm of the support surface.
  • the measurement of the current traction on the tow rope forms especially in connection with measured values of the speed and the direction of rotation the basis for the computer-aided control of the towing winch.
  • a wrap angle of the tow rope on the deflection roller of more than 90 °, in particular approximately 180 °, is preferably suitable in order to achieve reliable measured value detection even under different tow situations and elevation angles.

  • the towing winch has a sensor designed, for example, as an incremental sensor for detecting the rotational speed, rotational speed or direction of rotation of the deflection roller, in order to detect the issued cable length of the tow rope in this manner.
  • the towing winch has for this purpose two or more inductive sensors mounted on the carrier of the deflection roller or another pulley, which preferably scan a measuring disk. The pulses generated depending on the speed and direction are evaluated by the controller. From this, the length information about the tow rope is calculated and displayed by means of a display, for example a graphic display.

  • This metal insert which is for example embodied as a metal strand or detectable by means of a metal detector, thus defines an unambiguous measuring point in the direction of the main extension of the tow rope.
  • This measuring point is first detected by the insert, which is preferably arranged in an end facing the air sports device end of the tow rope during unwinding or undressing during the preparation for the start, so that in connection with the sensor for detecting the speed or rotational speed, the actual Extract length can be reliably determined.

  • the guide rollers are pivotally mounted together on a pivoting device, wherein the relative orientation and the distance between the guide rollers is invariable in operation.
  • the pivoting device can move in a pivoting range of up to 200 °, wherein the respective end positions are limited by fixed stops.
  • the contact of the pivoting device can be detected at one of these stops by means of a sensor, so as to quickly detect in particular unusual trajectory situations and possibly trigger a signal for the winch driver.
  • the guide roller pair By means of the guide roller pair, a simple and reliable angle measurement of the elevation with the elevation sensor is made possible during operation.
  • the signals generated by the elevation sensor are processed by the controller together with the current length of the towing cable and are then available in a display, for example on a graphic display, as height information.

  • the cable drum is associated with a winding guide with a slotted guide, so as to achieve a uniform winding pattern of the tow on the cable drum.
  • the winding process is superimposed with a coaxial with respect to the winding axis of the cable drum reversing stroke movement.
  • this can be generated mechanically due to the rotational movement of the drive unit, a lifting movement by a belt drive transmits the rotational movement of the drive unit to the winding guide.
  • the reversing stroke movement is realized in that the slotted guide has a drum, also referred to as a cam roller, with a peripheral groove incorporated in the lateral surface.
  • a planetary gear arranged within the cam roller serves to reduce the speed transmitted by the toothed belt and the corresponding increase in the torque.
  • This planetary gear is connected with its housing flange fixed to the cam roller. As a result, the cylindrical cam roller rotates at a slower fixed speed ratio with respect to the drive unit.
  • the reversing, sinusoidal lifting movement could also be generated by a connecting rod.

  • the friction wheel and the cutter wheel are rotatable and at the same time the friction wheel is biased by the biasing force of a spring element relative to the tow with the aid of a pressure roller as an abutment.
  • the movement of the tow is thereby transmitted to the friction wheel and so at the same time driven the knife wheel. As soon as one of the cutting knives on the knife wheel touches the tow rope, the cutting process begins.
  • the knife pushes the tow rope against the roller as an abutment until the tow rope is completely separated. Due to the defined cutting support of the cutting blade against the roller, the blade wear is very low.
  • the cutting process is triggered either purely mechanically by operating a handle or electrically by a driving lever. By only the traction of the tow is used for the separation process, the Seilkappvorraum is fully functional at any time even in case of failure of the electrical power supply.
