The 14-port hydraulic swivel assembly, part number 6364001434, serves as the central interface for fluid transfer in the Grove RT990 rough-terrain crane. It allows the crane's superstructure to rotate 360 degrees without restricting the flow of hydraulic oil to the various actuators, outriggers, and boom functions. By providing a dedicated path for each of the 14 hydraulic circuits, this component ensures that control signals and power remain consistent regardless of the turret position.
This assembly is specifically configured for the Grove RT990 model. It is designed to maintain seal integrity under operating pressures while allowing for smooth rotation of the upper machinery. The unit features internal porting that separates individual hydraulic lines to prevent cross-contamination of fluids between circuits.
Hydraulic swivels act as the rotational manifold for heavy machinery. They are typically mounted at the center of the machine's rotation axis. By housing multiple internal seals, the swivel allows hydraulic fluid to pass from the stationary chassis to the rotating upper structure, enabling the simultaneous operation of lifting, slewing, and steering functions without the risk of hose entanglement or mechanical failure during continuous rotation.
