Definitions

  • Such a reach truck is from the US-A-5, 052,882 known.
  • the invention has for its object to provide a reach truck with sideshift, in which the operation is simplified and accelerated.
  • Fig. 2 the wheel arms 18 can be seen as well as a side slider 20 which is horizontally 29iebar along a guide 22, as indicated by double arrow 24.
  • the guide 22 is connected to the lifting and lowering means on the mast 14, which in Fig. 2 indicated by dash-dotted lines.
  • the forks 16 are attached on the sideshifter.
  • an adjusting cylinder 26 engages to adjust it laterally according to double arrow 24.
  • an electric drive can be provided.
  • a lowering of the load-receiving means can only take place when the side slider 20 has center position. In the center position, the forks 16 are in the middle between the arms 18, as dashed in Fig. 2 is indicated.
  • the side shifter 20 When retracting the mast 14 between the wheel arms 18 and when lowering the side slider 20 in a position in which the mast 14 is located between the Radarmen 18, therefore, the side shifter 20 must have center position.
  • the side shifter 20 is associated with an analog sensor, which in Fig. 2 not shown. He is in Fig. 3 designated 30.
  • the analog sensor 30 generates an analog position signal in accordance with the position of the slider 20 relative to a centerline 32 (FIG. Fig. 2 ), which indicates the center position of the slider 20.
  • a signal from the sensor 30 goes to a display 32 in the cabin of the reach truck, so that the driver recognizes in which position the sideshift 20 is located.
  • the position signal of the analog sensor 30 is also on a control and regulating device 34, as used in reach trucks for the lifting and lowering operation or moving the mast and the lifting and lowering of the lifting device.
  • the device 34 is additionally capable of processing the position signal of the sensor 30.
  • an actuator in the cab of the truck is indicated, the actuation of the side slider 20 is adjusted.
  • any position of the side slider 20 can be approached in accordance with its deflection. This is done via the control and regulating device 34, which in turn gives a signal to a controller 38 for actuating the adjusting cylinder 26.
  • an actuator 40 may be provided, such as a switch button, upon actuation of the control and regulating device 34 automatically Center position of the side slider 20 anatomic.
  • An on-board computer 46 calculates the maximum travel speed for the traction motor, not shown, in accordance with stability criteria.
  • stability criteria include, for example, the load weight on the load handler, the height of the load handler, the inclination of the mast, etc.
  • the position of the side shifter 20 may be a safety criterion which is also input to the on-board computer 46 to flow in calculating the maximum travel speed ,

Claims (3)

  1. Chariot élévateur à mât coulissant, comportant un mât coulissant (14), que l'on peut faire coulisser sur un guidage horizontal, au moyen d'un entraînement du mât, en direction de la partie d'entraînement du chariot élévateur ou en s'en éloignant, un moyen de préhension de la charge (16) qui est adapté sur un dispositif latéral de coulissement (20), un guidage (22) du dispositif de coulissement latéral, monté contre le mât coulissant en pouvant être réglé en hauteur et en pouvant être actionné à l'aide d'un entraînement de levage et d'abaissement, qui guide le dispositif latéral de coulissement (20) dans son mouvement latéral, et un entraînement (26) du dispositif de coulissement latéral, ainsi qu'un dispositif électrique (34) de commande et de régulation, relié aux organes d'actionnement pour les opérations de levage et d'abaissement, pour les opérations de coulissement du mât et pour les opérations de coulissement latéral, et destiné aux entraînements correspondants,
    caractérisé
    en ce qu'il est prévu un détecteur analogique (30) relevant la position du dispositif latéral de coulissement(20), détecteur dont le signal de position est envoyé au dispositif (34) de commande et de régulation, et en ce que le dispositif (34) de commande et de régulation est relié à un organe d'actionnement particulier pour le dispositif latéral de coulissement (20), ou l'organe d'actionnement pour le dispositif latéral de coulissement est réalisé de façon que, lors de son actionnement, le dispositif latéral de coulissement (20) se déplace automatiquement dans une position prédéfinie, par exemple une position de milieu, et le dispositif (34) de commande et de régulation émet un signal sur l'entraînement du coulissement latéral (26) pour mettre en mouvement la position prédéfinie quand, avec l'organe (42) d'actionnement pour le coulissement du mât, est produit un signal pour le recul en arrière du mât (12) et/ou, avec l'organe d'actionnement (44) pour l'opération de levage ou d'abaissement, est produit un signal pour abaisser le moyen de préhension de la charge (16).
  2. Chariot élévateur à mât coulissant suivant la revendication 1, caractérisé en ce que l'organe d'actionnement (36) pour le dispositif latéral de coulissement (20) est réalisé sous la forme d'un émetteur de valeur de consigne qui, d'après sa course de réglage ou d'après son angle de réglage, émet un signal de valeur de consigne pour le dispositif (34) de commande et de régulation.
  3. Chariot élévateur à mât coulissant suivant l'une des revendications 1 ou 2, caractérisé en ce que le dispositif (34) de commande et de régulation est relié à un calculateur de bord (46), et/ou à une partie de celui-ci, en ce que le calculateur de bord (34), en tenant compte de critères de stabilité, limite la vitesse de déplacement et/ou la vitesse en courbe du chariot élévateur, et en ce que le signal de position du détecteur (30) est envoyé au calculateur de bord (46) pour modifier la vitesse de déplacement du chariot élévateur en fonction de la position du dispositif latéral de coulissement (20).
