Safe cable guidance even on long travels - and that in strong wind, sometimes heavy rain and corrosive sea air. With this challenge in mind, the two travelling trolleys were to be safely supplied with energy and data for this striking red shipyard crane, which matched the logo of the shipyard operator.
The travel of the crane trolleys of 122m had to be taken into account in the design of the cable guidance, as well as the considerable weight of 18kg per metre caused by the heavy cables. Due to the high frictional forces with this weight, a gliding energy chain was not an option for this. In addition, with a cable guidance of these dimensions, special care had to be taken to avoid a possible chain rise so that the e-chain cannot "rear up" due to the thrust force.
