Robust energy supply systems and cables for heavy-duty offshore cranes

For rotary cranes and gantry cranes on ships and offshore installations, we offer energy supply systems, cables, and trough systems that can also be designed as a complete system ready for connection. The E4.1 series plastic energy chains or heavy-duty roller energy chains are used on riser gantry cranes, which exceed festoon systems and steel energy chains primarily because of their corrosion-free operation and cable-friendly interior separation. A cable-friendly friction pair between the energy chain and the cable results in a greatly extended service life for the cables and the system.
For rotary cranes, an RBR rotating energy supply can be used instead of the usual slip rings. This solution provides modularity and freedom from maintenance. The rotary module features downtimes and maintenance intervals for the entire system that are up to 90% better than those of festooning systems and slip rings.
