A bending limiting device for hydraulic hoses at the end of an articulated lifting boom

摘要

Present invention relates to a bending limiting device 2 for hydraulic hoses 1 at the end 3 of an articulated lifting boom. Said lifting boom may be the lifting boom of a forest machine such as for example a harvester, where at the end 3 of the boom is a hanger 6 articulated in crosswise directions and for manipulating with the tree-trunks a gripper with rotator 11. At the end 3 of the boom are connections for hydraulic hoses 1, which are connected to rotator 11 and gripper at the end of the hanger 6. The aim of the present invention is to ensure that at the extreme mutual positions between the end 3 of the boom and hanger 6 said hydraulic hoses 1 do not become crumpled nor would bend too close to the connections of the hoses.
