Rotary Table(drilling rig) Rotary Table Drilling
A Rotary Table is a piece of equipment used in drilling to spin the drillstring to enable the drilling of a bore hole. It is located in the centre of the drill floor, and allows the drillstring to pass through. Rotary tables play an important role in the performance of drilling and workover service.
Rotary table is provided with high reliability and serviceability. Its structure has been designed to provide maximum strength to ensure larger load, increased safety and well-fit between bearings and gears. The table assembly was greatly simplified so it can be installed into the rotary housing and is easy to maintain. Finemade rotary tables meet the requirements of various drilling operations and work environments.
