We use electrical slip ring transfer power and signals between stationary and rotating parts. Slip ring consists a series of conductive rings and brushes that allow for continuous electrical connection despite rotation. Rotary joint also called rotary union or swivel joint, transfer fluids and air (such as hydraulic oil or water) between rotating and stationary parts.
If you’re looking for slipring and rotary joint for construction machinery. WayDun technology may help you. They have experience and products for cranes, excavators, truck mounted cranes, telescopic boom lift, fire trucks, stackers and reclaimers, etc.
