The safe guidance of hydraulic hoses in support legs of construction machinery, such as concrete pumps and mobile cranes, is of crucial importance here because these hoses need to provide the machines continuously and reliably, even under high mechanical stress and severe weather conditions. The E2 hydraulic chain can reliably guide cables and two hydraulic hoses. It not only protects the internal cables, but also uses a predefined minimum bend radius to prevent torsion to and kinking of the hoses.
