Rotary swivel for Terex T340

The rotary swivel 707A4251 acts as a central interface that enables continuous 360-degree rotation of the crane superstructure. It maintains the integrity of hydraulic and electrical circuits by allowing fluid or power to pass from the carrier frame to the upper works without restricting the movement of the crane. This component is specifically engineered for the Terex T340 model to ensure that control systems for the boom and outriggers remain operational during rotation.

This part is designed to fit the Terex T340 crane. It contains internal conduits that are individually sealed to prevent cross-contamination of fluids or external leakage. The assembly ensures that hydraulic pressure is maintained across the rotating joint, which is necessary for the consistent operation of the crane's hydraulic functions.

In heavy machinery, a rotary swivel functions as a bridge for power transmission. It allows the upper assembly to rotate freely while keeping hydraulic lines and electrical cables connected to the base. By providing a sealed path for pressurized oil, the swivel prevents system pressure drops and allows for the simultaneous operation of multiple hydraulic circuits while the machine is in motion.
