Drilling Rig with Independently Driven Rotary Table

Main Features
1. Based on general drilling mechanism, our drilling rig isolates rotary table from drawworks drive. Therefore, rotary table speed and torque as well as mud pump stroke can be practically adjusted in accordance with actual applications, which is the perfect foundation for customized drilling effects and automatic drilling system.

2. We adopt digital automatic control technology for rotary table and auto bit feeding system. Our drill machine offers similar performance as digital control variable frequency rig yet in a more cost effective manner.

3. Our drilling rig with independently driven rotary table is endowed with touch screen so as to offer in-time adjustments on drilling parameters to fit actual applications. Operatives avail from drastically reduced work load and enhanced working efficiency. Moreover, value-added functions, such as parameter display, store, regulation and remote management, are also available to meet customer satisfaction.
