Swivel joint for Terex A380

The swivel joint is a hydraulic component designed to manage the flow of fluids between stationary and rotating machine sections. It allows hydraulic oil to pass from the chassis to the superstructure, enabling continuous rotation of the crane without restricting the hydraulic circuits that power the boom and other attachments. By maintaining a sealed path for pressurized fluid, this component ensures that the hydraulic systems remain pressurized and functional regardless of the rotation angle of the crane upper structure.

This specific component is compatible with the Terex A380 crane. It is typically installed at the center of the slewing ring assembly to serve as the primary interface for hydraulic power transmission. The unit is engineered to accommodate the specific flow requirements and pressure ratings of the machine hydraulic system, ensuring that fluid transfer occurs without leakage or significant pressure drops during operation.

Swivel joints are internal assemblies featuring multiple channels and sealing surfaces that isolate different hydraulic lines. In heavy machinery, these components are necessary for any system requiring 360-degree rotation. They ensure that hydraulic control signals and power delivery remain consistent while the machine performs lifting or slewing tasks.
