Rotary Table
Rigs, Derricks Etc. manufactures two size rotary tables 22K and 15K. The halo design can rotate both clockwise and counterclockwise without disconnecting any hoses all from the same console and valve. This design allows more freedom on the rig floor then previous designs that only allowing the operator to go clockwise.

RDE's 22K Hydraulic Rotary Table is designed to add high speed, high torque rotational capacity to snubbing units. This unit is mounted above the snubbing unit’s hydraulic cylinders. A pneumatic or hydraulically actuated slip assembly (supplied by others) can be bolted to the rotary’s top mounting flange to accommodate both pipe pulling (tension) and pipe snubbing (compression) operations.
RDE's features a roller type thrust bearing instead of a thrust bushing. This bearing provides enhanced performance in applications where pipe must be “snubbed” into the well while rotating for extended periods of time. Such applications may include shallow drilling, milling, window cutting, and side tracking.
The Rotary Table’s large bore design 11.06 inch ID will readily allow the passage of large downhole tools. This feature significantly reduces tripping times when compared to other systems which must be removed when large diameter tools such as mills, packers, or side pocket mandrels are encountered.
Four single speed hydraulic motors with Three piece shafts directly drive the Rotary Table to provide high torque capacity in a compact package. High efficiency Rineer MO-15 vane type motors are powered by the snubbing unit’s hydraulic power supply to eliminate the need for additional power units. Precise speed, direction, and torque control are achieved by means of pilot operated control valves (supplied separately). Note: A two speed motor option is available. Motors are interconnected by welded supply and return manifolds with split flange O-ring connections to provide optimum reliability in service.
Tensile loads (pulling pipe) are carried by a lubricated roller bearing. Compressive loads (snubbing pipe) are transferred through a composite self lubricating thrust bearing assembly. For extreme drilling applications, long term heavy compressive loads will be encountered with simultaneous high speed rotation. Lubricated bronze bushings absorb any radial loads resulting from eccentric slip assembly loading.
