Used in Oil and Offshore operations

The rotary joint in the crane provides the necessary power to perform the necessary movements and lifting of the crane, therefore the rotary transmission package is of very high importance.  

Penlink offers a wide range of solution, both hydraulic rotary unions and electrical slip rings. We can also integrate fiber optical channels and high accuracy encoder (slewing). 

We have a very wide range of ATEX, IECEx certified slip rings! We can also certify custom slip rings for small volume projects. If the crane operates in different zones or it needs to be an emergency use situation, we can offer combined solutions using two rotary joints. 

If requirements are needed for high data speeds, we can offer 1Gb/s data transfer in an electrical slip ring module. Our signal slip ring is sealed to make sure carbon dust from power rings doesn’t penetrate and disturb signal rings over time. 

We offer separated chambers in the slip ring due to new regulations in the industry!
