Long Life Offshore Deck Crane Slip Ring 60 Circuits 15000 RPM Gold Contact Aluminum Alloy

SP056060-OC Long Life High-Speed Slip Ring for Offshore Deck Crane

Product Overview

The SP056060-OC long life slip ring carries power and instrumentation signals across the slewing joint of offshore deck cranes. Sixty circuits support slew, hoist and luff drives together with load moment indicators, anemometers and anti collision sensors, and the 50 million revolution service life keeps maintenance windows long in remote offshore locations. The sealed aluminum alloy housing resists salt fog, humidity and mechanical shock.
