Definitions

  • Fig. 1 shows a lifting device with a bow-shaped foot lever 1 and with a pedal-operated locking pawl 2 before the load 3 is lifted.
  • Fig. 2 shows a lifting device after lifting the load.
  • the load is deposited by foot pressure 10 on the tilting edge 11.
  • Fig. 3 shows a bow-shaped additional device 20, with rollers 21, which make it possible to raise the front wheels 22 slightly in order to overcome level transitions 23.
  • Fig. 4 shows a hand lever actuation 30, with locking 31 of the lifting position which can also be released by hand.
  • FIG. 5 shows a platform 41 that is moved via horizontally displaceable wedges 40. The actuation takes place via tilting 42, 43 to activate 4, or to release 45 the locking device 46.
  • FIG. 6 shows a device similar to FIG. 5, but with hydrostatic, for example pneumatic, actuation.
  • the rod 54 with the wedges is displaced via the roller 51 and the pressure plate 52 and, supported on the bearing 53.
  • the bracket 56 pressed against the rod via springs 55 acts as a frictional brake which is released during the displacement of the rod by the reaction force of the force cell.
  • the force of the return spring 57 is determined such that a lower medium pressure only releases the braking effect of the bracket 56 and controls the return of the rod 54, whereas a higher pressure causes the load 58 to be lifted.
  • Fig. 1 roller-mounted lifting device with bow-shaped lever arm for foot actuation before lifting the load.
  • Fig. 2 roller-mounted lifting device with bow-shaped lever arm for foot actuation with raised load.
  • Fig. 4 Hand lever operated lifting device.
  • FIG. 5 Foot lever operated lifting device with wedge tracks.
  • Fig. 6 Hydrostatically operated and acting over wedges lifting device with frictional locking of the lifting position.

Abstract

Dispositif de levage pour le levage de charges comportant un élément de transmission de la force et un élément d'arrêt. La figure montre une plate-forme à commande hydrostatique, par exemple pneumatique, mobile au-dessus de coins de déplaçant horizontalement. Lorsqu'on introduit un fluide sous pression dans la cellule (50) de force, la tige (54) comportant les coins se déplace par l'intermédiaire d'un galet (57) et d'une plaque d'appui (52) en s'appuyant sur la suspension (53). L'étrier (56) comprimé contre la tige par l'intermédiaire de ressorts (55) agit en position de repos comme un frein à friction qui se desserre pendant le déplacement de la tige sous l'effet de la force de réaction de la cellule de force. La force du ressort de rappel (57) est déterminée de telle manière qu'une faible pression du fluide libère uniquement l'effet de freinage de l'étrier (56) et commande le retour de la tige (54), alors qu'une pression plus élevée provoque le levage de la charge (58).
