Top Drive System with API Verification for Petroleum and Gas Drilling Rig

Our top drive systems offer unmatched performance and reliability while continuing to drive longer, heavier strings through complex formations.

For decades, the industry has relied on brands like Varco, National, and Hydralift to push the boundaries of equipment design. Building upon this legacy of experience in electric top drive systems, NOV continues to produce world-class drilling systems that are durable, reliable, and able to meet the performance demands of drilling today. With over 2,900 top drive systems delivered, we can offer products ranging from the smallest hydraulic power swivel (HPS) units to the largest AC-powered offshore drilling systems with hoisting capacities up to 1,500 tons.
Top drive system is a mechanical device used to rotate, raise and lower drill strings in oil and gas drilling operations. It consists of a motor, rotating head, power swivel, and hoisting mechanism, which work together to perform the drilling operation. The motor is connected to an electric generator that powers the top drive system
