The invention relates to an arrangement and a method for controlling a boom in a rock drilling equipment, the boom (1) comprising several actuating devices (18a to 18d) connected in parallel to supply and return lines (16, 17) for hydraulic fluid in such a way that a selector valve (19a to 19d) is provided foreach actuating device (18a to 18d) between the actuating device end the lines (16, 17); and a proportional valve (13) connected to the hydraulic lines (16,17)for regulating the flow of hydraulic fluid. The invention further comprises a control unit (12) where separate set values are preset for each actuating device (18a to 18d) so that the speed of movement of each actuating device is proportional to the range of movement of the respective control member (11a to 11d).

Système et procédé de commande d'une flèche dans un matériel de forage de la roche. La flèche (1) comporte plusieurs dispositifs de commande (18a à 18d) reliés en parallèle à des tuyaux d'alimentation et de retour (16, 17) pour un liquide hydraulique, une vanne sélectrice (19a à 19d), associée à chaque dispositif de commande (18a à 18d), étant prévue entre le dispositif et les tuyaux (16, 17); ainsi qu'une vanne de dosage (13) reliée aux tuyaux hydrauliques (16, 17) et destinée à réguler le débit de liquide hydraulique. On a également prévu une unité de commande (12) dans laquelle on a présélectionné des valeurs de consigne séparées pour chacun des dispositifs de commande (18a à 18d) de sorte que la vitesse du déplacement de chaque dispositif de commande soit proportionnelle à l'amplitude du mouvement de l'élément de commande respectif (11a à 11d).
