Solution
The operators opted for an igus e-chain as their energy supply solution. The entire system consists of a stainless steel trough, in which the
4040RHD energy chain lies. This is a very rugged chain, which is resistant to sea water, oil and UV rays. The travel of the energy chain is about 65 metres and the whole chain is consistently equipped with rollers to reduce friction and keep the push/pull forces low. A floating moving end of the energy supply system continues to serve as a compensator for lateral misalignment. It can compensate for a clearance of about +/- 50mm to the right and left and is guided through the
trough, so that the chain is always in line with it. The energy chain consists of
chainflex cables by igus, also resistant to sea water and UV rays and especially designed for continuous flexing in the chain.
