The safe guidance of hydraulic hoses in support legs on construction machinery, such as concrete pumps or mobile cranes, plays a crucial role, as they need to supply the machines reliably and permanently, even under high mechanical stress and severe weather conditions. The E2 bow chain can be used to safely guide cables and two hydraulic hoses. It not only protects the internal cable, but also prevents torsion and buckling of the hose due to the predefined minimum bending radius.
