Slip Rings for Smaller Offshore Cranes

At Penlink, our strength is to produce customized slip rings for harsh environments. We know what technical specifications are important for slip rings to minimize downtime for cranes and deck machinery used in offshore environments.

To get a secure transfer of electricity from the stationary ship to the rotating crane the slip ring must be carefully designed. The slip rings can be divided into completely separated compartments, to ensure a redundant and safe transfer. If one compartment is subjected to a fault another completely isolated compartment can fulfill the slip ring function.

All Penlink crane slip rings can be equipped with fiber optical rotary joints. We can supply everything from 1 fiber optical channel to as many as you need, both multimode and single mode, and the connectors of your choice. The slip rings can be equipped with rotation sensors, such as gyros or accelerometers that can accurately and absolutely give the rotation angle of the crane.
