Title (EN) DEVICE FOR GATHERING LOGGING WASTE IN PARTICULAR
(FR) DISPOSITIF COLLECTEUR DE RESIDUS D'EXPLOITATION
Abstract:
(EN) A device for gathering of logging waste in particular, by whose means logging waste is gathered from the ground by means of a dragging movement. The device that is substituted for a device that gathers waste by means of a grasping movement includes an arm (2) that has been connected with the arm of a crane (1) by the intermediate of an articulated joint (3), which arm (2) is pivoted by means of a power unit (4) around the articulated joint (3) against a backup plate (5) so as to incline the grab into a dragging position. The arms (6b) of the grab may also be provided with an arm (7), which, when it has been pivoted to the side (7a), prevents penetration of the grab arms (6b) below the ground surface and which, when they have been pivoted downwards (7b), permit compacting by means of the grab by means of a grab opening movement.
(FR) Cette invention se rapporte à un dispositif collecteur conçu particulièrement pour ramasser des résidus d'exploitation jonchant le sol, en une action de ratissage. Ce dispositif, qui remplace un autre dispositif ramassant les résidus par préhension, comporte un bras (2) qui est relié au bras d'une grue (1) par l'intermédiaire d'un joint articulé (3), un vérin de commande (4) permettant de faire pivoter ledit bras (2) autour du joint articulé (3) à l'encontre de la force exercée par une plaque d'appui (5) de manière à incliner la pince en position de ratissage. Les bras (6b) de la pince peuvent également être associés chacun à un bras (7), lesdits bras (7) empêchant, après pivotement sur le côté (7a), les bras de la pince (6b) de pénétrer sous la surface du sol et permettant, après pivotement vers le bas (7b), le compactage par ouverture de la pince.
