Abstract

Anordning og fremgangsmåte for å styre en bom ved et fjellboreutstyr, idet bommen (1) innbefatter flere påvirkningsanordninger (18a-18d) forbundet parallelt for tilførsel og retur (16, 17) av hydraulisk fluid. En velgerventil (19a-19d) er anordnet for hver påvirkningsanordning (18a-18d) mellom påvirkningsanordningene og forsynings-ledningene (16, 17). En proporsjonal ventil (13) er forbundet med de hydrauliske ledningene (16,17) for å regulere strømmen av hydraulisk fluid. Videre er det anordnet en styreenhet (12) hvor separate innstillingsverdier er forhåndsinnstilt for hver påvirkningsanordning (18a-18d) slik at bevegelseshastigheten til hver påvirkningsanordning er proporsjonal med bevegelsesområdet til de respektive styreelementene
