How Do Rotary Unions Work in Excavators?

On an excavator, rotary unions allow hydraulic fluid to be transferred between the cab and track base while continuously rotating 360 degrees. The fluid supplies the track drive system allowing the excavator to move.

Applications suitable for hydraulic rotary unions and swivel joints include forestry (harvesting, loading, material handling), heavy construction (earth moving, land clearing, crane hoisting / material handling), pipeline construction (clearing, grading, ditching, backfilling), landscaping (irrigation, preparation), and surface mining.
