Title (EN) METHOD IN A BOOM ASSEMBLY LOADER AND A BOOM ASSEMBLY LOADER
(FR) PROCEDE POUR CHARGEUSE A ASSEMBLAGE DE FLECHE ET CHARGEUSE A ASSEMBLAGE DE FLECHE
Abstract:
(EN) The invention relates to a method in a boom loader, and a boom loader in connection with a work machine (TK). A first boom part (1) in the boom assembly is articulated with a first joint (N1) to the frame of a work machine (TK) driving the boom loader (PK), to be rotatable with respect to the frame by a first actuator (T1). A second boom part (2) in the boom assembly is articulated to the second end (1b) of the first boom part (1) by means of a second joint (N2), to be rotatable in relation to the first boom part (1) by means of a second actuator (T2). When applying the method, the boom loader is used optionally in at least two modes (A, B), wherein when operating in mode (A), the first joint (N1) is locked, and loading is performed with the second boom part (2) and with means for carrying the load (3...) by using the second actuator (T2) at least partly, the second joint (N2) being active; and wherein when operating in mode (B), the second joint (N2) is locked, and loading is performed with a combination of the first (1) and the second (2) boom parts as well as with the means for carrying the load (3...) by using the first actuator (T1) at least partly, the first joint (N1) being active.
(FR) L'invention concerne un procédé pour chargeuse à assemblage de flèche et une chargeuse à assemblage de flèche utilisée avec un engin de travail (TK). Une première partie de la flèche (1) comprise dans l'assemblage de flèche est reliée articulée par un premier pivot (N1) au châssis de l'engin de travail (TK) de manière à pouvoir pivoter par rapport au châssis au moyen d'un premier actionneur (T1). Une deuxième partie de la flèche (2) faisant parti de l'assemblage de flèche est reliée articulée à la deuxième extrémité (1b) de la première partie de la flèche (1) au moyen d'un deuxième pivot (N2), de manière à pouvoir pivoter en rapport avec la première partie de la flèche (1) au moyen d'un deuxième actionneur (T2). Selon le procédé de l'invention, la chargeuse à flèche est utilisée en option dans au moins deux modes (A, B); en mode (A), le premier pivot (N1) est verrouillé et le chargement s'effectue au moyen de la deuxième partie de la flèche (2) et d'un système de transport de charges (3...), par l'utilisation du deuxième actionneur (T2) au moins partiellement, le deuxième pivot (N2) étant actif. En mode (B), le deuxième pivot (N2) est verrouillé et le chargement s'effectue par une combinaison des première (1) et deuxième (2) parties de la flèche ainsi que par le système de transport de charges (3...) qui utilise le premier actionneur (T1) au moins partiellement, le premier pivot (N1) étant actif.
