Abstract

The invention relates to a crane (1) with improved guidance of flexible hose (12) from the pillar (3) to the first arm (4) of the crane (1) and a forestry vehicle comprising said crane. The pillar (3) of the crane is rotatably mounted on the base frame (2) and the first arm (4) is movably mounted on the pillar via the joint (8). At least one flexible hose (12) connects a connection point (13) on the pillar (3) or the base frame (2) to the end of the first arm (4), where the at least one flexible hose (12) exits. Due to the movable mounting of the arm (4) the distance between the connection point (13) and the exit from the first arm (4) changes, which leads to coiling of the flexible hose (12) inside the arm (4). To prevent this, the first arm (4) is further provided with: - an opening (20) on the back part (43) of the first arm (4) immediately adjacent to the first joint (8) to allow entering of the at least one flexible hose (12) into the interior of the arm (4), - a movably mounted clamp (23) installed in the bottom part (42) of the arm (4) and arranged to compress at least one flexible hose (12) against the bottom part (42) of the arm (4), where a sliding surface (24) is provided to prevent slipping of the flexible hose (12), - two supporting rollers (21, 22), wherein at each side of the said opening (20) one supporting roller (21, 22) is installed, which allows the at least one flexible hose (12) to roll or at least touch the roller (21, 22), and - at least one sliding surface (16, 17) from a thin material joined or glued on the inner surface of the upper part (41) of the arm (4), which allows sliding of the at least one flexible hose (12).
