Direct Drive Drawworks System
This direct drive drawworks system is designed for efficient drilling operations. It features dual motors that directly drive the drum, reducing maintenance and improving control.




Technical Specifications
Overview
Advanced Direct Drive Drawworks
The Direct Drive Drawworks System features double motors that directly drive the drum, eliminating the need for reduction gears, couplings, and complex lubrication systems. This innovative design results in a unit that is 40% smaller and 25% lighter than traditional models, while reducing maintenance requirements by up to 80%. Equipped with AC VFD drives and integrated automatic driller's control software, it provides precise control over ROP, WOB, and torque for demanding petroleum prospecting applications.
