Patent abstract
A remotely operated lifting top drive cement head has a high tensile strength and the ability to swivel or rotate. The cement head permits selective launching of darts, setting plugs, balls or other objects which can be held in place within the cement head without being damaged or washed away by slurry flow, but which can be launched as desired. The cement head can be remotely operated without requiring personnel to be lifted off the rig floor to actuate the tool or observe tool status.
