Definitions

  • the invention relates to an operating device for a loading crane, with a screen on which a load exerted by load and crane torque in relation to its maximum value can be displayed.
  • a limitation of the torque exerted on the storage of a loading crane is necessary in the sense of an overload protection in order to avoid an overuse of structural components of the crane.
  • the invention avoids the drawback presented in that the direction of the plane defined by the crane relative to a horizontal plane (swivel angle) and the momentary torque can be represented together with a curve which represents the maximum permissible torque for the entire angular range.
  • the loading crane shown has a on a base 8 about a vertical axis 14 rotatable stand 3, which inclined counter to the direction of the boom 5 to the rear
  • the pivot axis 4, about which the boom 5 can be moved up and down by means of the unit 13, is slightly displaced from the center of the base 8 to that side on which the tilting arm 7 is to be guided past the upright 3.
  • the Kipparm 7, which carries the only schematically illustrated, multi-part extension arm 11 is pivotable about a central axis 9 about the boom 5 down.
  • the movement of the tilting arm 7 is effected by a hydraulic unit 6, which is fastened on the one hand to the tilting arm, on the other hand to two pairs of pivoting levers.
  • the pivot levers 1 and 2 are in turn connected either to the boom 5 or 7 with the Kipparm.
  • the pressure in the lifting cylinder 13 is usually the measure of the torque exerted by the crane and the load attached thereto.
  • Each movement in the crane plane that is to say the drawing plane in FIG. 1, leads to a steady approach to the maximum value permissible with regard to overloading or tilting safety.
  • the situation is different for rotations about the vertical axis 14
  • information is conveyed to the operating personnel, which also indicates the approach to the maximum permissible value of the torque in the case of pivoting movements.
  • the direction of the crane can also be characterized by a radius in the form of a beam 25 emanating from the axis 14.
  • the length of this bar can be chosen to be constant or proportional to the distance of the crane tip of the axis 14.
