At BINI we have been designing and developing hydraulic swivel joints and electrical slip rings for a broad range of applications for over 65 years. BINI creates its products starting from the very beginning, from the idea, giving it form in the first prototype, testing it, perfecting it, and finally producing it. Hydraulic swivel joints permit transfer of pressurised fluids between two parts of a piece of equipment that rotate with respect to one another. Electrical slip rings allow transmission of electricity (AC and DC) and analogue/digital signals between rotating and stationary structures. Hydraulic swivel joints with electrical slip rings permit the transfer of pressurized fluids while also ensuring electrical continuity between rotating and fixed structures.
