Definitions

  • the invention relates to a crane with an operable by an operator via manual input units electronic control for actuating drives for at least one hoist and crane movements, the manual input units in their sensitivity (resolution) are adjustable, according to the preamble of claim 1.
  • a crane from JP 2000 086 155.
  • a crane regularly not only has a drive for at least one hoist for lifting a load, but also one or more drives for the execution of crane movements.
  • Such crane movements can be seen for example in the adjustment of the inclination of the boom of the crane and in particular in pivotal movements of the boom about a vertical axis of rotation.
  • the actuation of the respective drives takes place via manual input units, which are usually designed in the form of control levers. As a result of different degrees of deflection of such control levers, the speed of the respective drive coupled thereto can be set as desired to different values.
  • Modern cranes are regularly provided with an electronic control, which receives its control commands via the already mentioned manual input units and converts them into corresponding signals for the control of the drives.
  • an electronic control which receives its control commands via the already mentioned manual input units and converts them into corresponding signals for the control of the drives.
  • Object of the present invention is to develop a crane of the generic type to the effect that according to the requirements of each lifting task to be solved with the crane, the best possible operation can be guaranteed by crane operators despite their different degrees of behavior.
  • the spread of the manual input units is expediently increased significantly compared to the normal setting, thus reducing the sensitivity, so that a sensitive adjustment is ensured even by less sensitive acting operators.
  • the spread of the manual input units for the assembly operation can be so pronounced that the maximum speed of the respective associated drive normally no longer can be reached, but only by switching to another mode is controlled.
  • the invention provides that the sensitivity of the manual input units is not adjusted linearly but in the form of a characteristic in which there is a comparatively high resolution of the setting movements in an initial fine control range (large spread) and in the wider range a progressively changing profile the characteristic for rapid achievement of the maximum speed of the respective drive (smaller spread) is provided.
  • the inventive design of the electronic control of a crane makes it possible, the behavior of the manual input units of the crane to the individual needs Adjust the respective crane operator and the respective lifting task in a particularly favorable manner.
  • the crane operator can by a corresponding programming of his control the resolution on the control levers on a wide spread and set long ramp times. This can ensure that even with significant movements of the control lever used as manual input units only slow speeds are caused on the drives.
  • the controller can be set for high-speed operation, which is particularly advantageous on construction sites when lifting smaller loads with low shearing of the hoist cable to perform fast movements with high dynamics and short ramp times.
  • the structural complexity required for the implementation of the present invention is low, as this essentially only corresponding storage space in the controller and a software program must be provided.

Claims (9)

  1. Grue comportant une commande électronique pouvant être utilisée par un opérateur par l'intermédiaire d'unités d'entrée manuelles et destinée à actionner des entraînements pour au moins un mécanisme de levage et pour les mouvements de grue, la sensibilité (résolution) des unités d'entrée manuelles pouvant être réglée, la commande électronique disposant d'au moins deux réglages pouvant être sélectionnés par l'opérateur, lesquels prédéterminent des sensibilités différentes des unités d'entrée manuelles déterminées pour chaque mode de fonctionnement de la grue,
    caractérisée en ce que les réglages divergeant du réglage normal peuvent être réglés par l'opérateur, notamment par l'intermédiaire d'un écran tactile de la commande électronique.
  2. Grue selon la revendication 1,
    caractérisée en ce qu'il est prévu au moins un réglage pour le mode montage (réglage montage), avec lequel, par rapport à un réglage normal prédéterminé à l'usine, l'excursion d'une unité d'entrée manuelle dans une position déterminée engendre à chaque fois un mouvement nettement plus lent de l'entraînement concerné.
  3. Grue-selon l'une des revendications 1 ou 2,
    caractérisée en ce qu'il est prévu au moins un réglage de mode rapide, avec lequel, par rapport à un réglage normal prédéterminé à l'usine, l'excursion d'une unité d'entrée manuelle dans une position déterminée engendre à chaque fois un mouvement relativement plus rapide de l'entraînement concerné.
  4. Grue selon l'une des revendications 2 ou 3,
    caractérisée en ce que le réglage normal prédéterminé à l'usine est mémorisé dans la commande électronique de façon protégée, de telle manière qu'une modification ne peut être réalisée que par un personnel formé à cet effet.
  5. Grue selon l'une des revendications 2 à 4,
    caractérisée en ce que, pour le mode montage, l'écartement de la plage d'excursion des unités d'entrée manuelles est réglé tellement grand que la vitesse maximale de l'entraînement associé ne peut être réglée que par le passage à un autre mode de fonctionnement.
  6. Grue selon l'une des revendications 3 à 5,
    caractérisée en ce que la sensibilité des unités d'entrée manuelles présente une courbe caractéristique, selon laquelle, dans une zone de commande fine de départ, on dispose d'une résolution relativement haute des mouvements de réglage et, dans la zone suivante, il est prévu un développement de la courbe caractéristique variant progressivement pour atteindre rapidement la vitesse maximale de l'entraînement concerné.
  7. Grue selon l'une des revendications 1 à 6,
    caractérisée en ce que la commande électronique dispose d'un programme de contrôle, lequel exclut la mémorisation de réglages avec lesquels les valeurs de vitesse et dynamique pouvant être atteintes seraient situées en dehors des valeurs admissibles pour la grue.
  8. Grue selon l'une des revendications 1 à 7,
    caractérisée en ce que les réglages sont enregistrés individuellement pour chaque opérateur, notamment sous une forme protégée par un code personnel.
  9. Grue selon l'une des revendications 1 à 8,
    caractérisée en ce que le réglage de l'opérateur sélectionné pour le fonctionnement peut être continuellement affiché.
