Abstract (en)
[origin: WO8103192A1] Quick coupling device for implement carrying machines (6, 7) such as loading machines and excavators. The device comprises an implement holder (1) carried by the implement and a suspension plate (5) carried by the machine, which cooperate for removable attachment of the implement (16) to the machine (6, 7). According to the invention the suspension plate (5) is provided with wedge shaped, preferably conic suspension elements (8), and the implement holder (1) is provided with suspension recesses (2) having the corresponding shape, so that the narrow ends of the suspension elements can be guided into the broad opening of the corresponding recesses (2) when the suspension plate is lifted upwards. The device is also provided with means (9), preferably hydraulic piston/cylinder units, for locking the suspension elements (8) in the corresponding recesses (2) while at the same time clamping the suspension plate (5) against the implement holder (1).

Dispositif d'accouplement rapide pour des machines portant un outil (6, 7) telles que des machines de chargement et des excavatrices. Le dispositif comprend un porte-outil porte par l'outil et une plaque de suspension (5) porte par la machine qui coopere pour permettre la fixation amovible de l'outil (16) sur la machine (6, 7). Selon l'invention, la plaque de suspension (5) est pourvue d'elements de suspension formes en coin, de preference coniques (8), et le support d'outil (1) est pourvu d'evidements de suspension (2) ayant la forme correspondante, de sorte que les extremites etroites des elements de suspension puissent etre guidees dans l'ouverture large des evidements correspondants (2) lorsque la plaque de suspension est relevee vers le haut. Le dispositif est egalement pourvu de moyens (9), de preference des unites pistons/cylindres hydrauliques pour verrouiller les elements de suspension (8) dans les evidements correspondants (2) tout en bridant en meme temps la plaque de suspension (5) contre le porte-outil (1).
