The 6445Z77 seal kit provides the required sealing components for the swivel joint mechanism. The swivel, or rotary union, acts as the interface that transfers hydraulic fluid between the rotating superstructure and the stationary carrier of the crane. By maintaining a pressurized seal, this kit prevents fluid leakage and ensures the transmission of hydraulic power to the various actuators located on the upper crane assembly.

This kit is compatible with the P&H CN 190 lattice crane. The swivel joint experiences constant movement during crane operation, which necessitates periodic maintenance of its internal sealing elements to prevent pressure loss and erratic system behavior. This set includes various O-rings and backup rings configured for the specific dimensions of the swivel assembly.

In hydraulic machinery, a swivel joint allows for continuous rotation of the superstructure without tangling hydraulic hoses. The seals within the unit are responsible for containing high-pressure fluid while allowing the internal shaft to rotate freely. Proper sealing is necessary to maintain the hydraulic pressure required for consistent crane performance during lifting operations.
