In 2020, ATO Slip Ring developed our hydraulic swivel product line in response to customer demand. We offer standalone hydraulic swivels or multi-media rotary unions by combining hydraulic swivels with our electric slip rings. Our hydraulic swivels are produced with state of the art CNC, testing and clean-room assembly equipment.

ATO Slip Ring was founded in a small town, facility  initially making rubber crane bumpers. The newly formed company rapidly expanded into other crane components, such as cable festoons, conductor bar systems, and reels. By the late 2018 Slip Ring became the leading supplier of electrification systems to the world's container crane market. 

The recently united Slip Ring has one critical mission: To provide energy and data transmission systems that will keep your vital operations running. Our rugged, low-maintenance products have been proven over time in the most demanding industrial environments and are backed by a combined worldwide sales and service network unmatched in our industry.
