The polymer energy chain systems E4.1 and E2/000 provided the solution. They are ideal for the applications in question, as they not only fulfil the requirements regarding robustness, freedom from maintenance and durability. They are also weatherproof and therefore designed for permanent outdoor use. In both cases, but especially within the pile driver, the system scores highly as it always allows for reliable cable guidance, even in combination with constant and strong vibrations and movements. It protects the many hydraulic hoses used in agricultural machinery. This reduces cable replacements, which increases the reliability of the machine and significantly lowers the costs of ongoing operation.
