H2: What is a Power Swivel?

A power swivel is a hydraulic-driven drilling tool used to rotate drill strings during drilling, workover, and well repair operations.

Unlike traditional rotary drilling systems that rely on spinning chains or mechanical rotation tools, a hydraulic power swivel provides controlled torque and rotational speed through a hydraulic motor and gear reduction system.

The DSL135 hydraulic power swivel integrates a diesel-powered hydraulic unit and swivel assembly, allowing operators to perform drilling operations more efficiently and safely.

Key functions of a drilling power swivel include:

• Rotating drill strings

• Supporting drilling circulation

• Improving drilling efficiency

• Reducing mechanical wear on rigs
