Rotary Joints

Our rotary joints (also known as swivel joints) are designed to manage hydraulic flow between fixed and rotating components without leakage or performance loss. Built for continuous operation across excavators, cranes, and aerial work platforms, these units perform reliably in high-pressure, high-debris, or temperature-extreme environments. Each rotary joint is configured to the machine’s hydraulic system, from 1-port to 50-port designs, ensuring precise fluid transfer, seal integrity, and mechanical balance. Integrated electric slip rings can be added for signal or power transmission, enabling advanced control systems within compact assemblies. Whether it’s a truck-mounted boom lift, an excavator or a crawler crane, Hycom Engineering rotary joints deliver smooth, jerk-free rotation and stable motion control, essential for operator safety and system durability.
