In a telescopic arm device having three arm parts (4, 5, 6), flexible hydraulic hoses (12) extend between connection places (13, 14) on a base arm part (4) and the outermost (5) of the arm parts. The lines are between these connection places arranged in a bight (15), from which the lines run in generally the same direction to the connection places (13, 14). Between the bight (15) and the connection place (14) on the outer arm part, the lines run in tubes secured to the second and third parts (5, 6), said tubes co-operating telescopingly so as to guide the lines to extend in a generally straight path between the bight (15) and the connection place (14) on the outer arm part (5). |
