The Invention relates to lift truck with two lifting and lowering arms, for the activation of which the lift truck possesses an on-board hydraulic system with a pressure generating means, together with a pressure equalizing vessel and operational cylinder. Further, on the forward end of the lift truck an implement carrier frame is hingedly linked by pivot pins for the attachment of a working implement. The means of securing the so attached implement and means for locking and unlocking of locking pins, therein characterized, in that each of the locking pins, with the aid of a pressure cylinder, is operable and an on-board hydraulic system with branched lines feeds hydraulic fluid through an axial boring in at least one of the pivot pins, with which the implement carrier frame is hingedly linked to the power arms of the lift truck.

La présente invention a trait à un chariot élévateur comportant deux bras qui peuvent monter et descendre et qui sont activés par un système hydraulique intégré au chariot. Ce système hydraulique est doté d'un dispositif générant de la pression ainsi que d'un dispositif d'équilibrage de la pression et d'un cylindre opérationnel. En outre, à l'extrémité avant du chariot élévateur, un bâti servant à porter des attachements est relié au chariot au moyen de tiges articulées permettant de fixer les attachements. Les dispositifs de fixation des attachements et ceux permettant de verrouiller et de déverrouiller des goupilles, chacune pouvant être activée à l'aide d'un cylindre de compression, sont opérationnels. Le système hydraulique intégré est doté de conduites ramifiées assurant l'alimentation en fluide hydraulique par un orifice axial réalisé dans au moins une des tiges d'articulation au moyen desquelles le bâti porteur d'attachements est relié de façon articulée aux bras motorisés du chariot élévateur.
