The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: With its hydraulic dual-cylinder system, the clamp delivers synchronized jaw movement, ensuring a balanced and secure grip on the drill pipe. This method surpasses the traditional single-sided clamping, providing greater efficiency and reliability.
Floating pin mechanism: An innovative floating pin, backed by a spring system, deftly compensates for thread displacement during make-up operations, enhancing the precision and integrity of pipe connections.

2. Hydraulic drive system
Hydraulic cylinder and piston: Seamlessly controlled by the solenoid valve, the precision-engineered hydraulic cylinder propels the piston, ensuring flawless extension and retraction of the jaw support. This sophisticated mechanism guarantees efficient clamping and release actions with absolute precision.
Sealing technology: Our pioneering oil pouring cup leak-proof design, coupled with the innovative back-clamp sealing pin, significantly reduces hydraulic oil leakage risks. This breakthrough in sealing technology promises both reliability and enhanced operational safety.

3. Clamping actuator
Replaceable jaw module: Experience the next level of drilling efficiency with our ANSYS-verified optimized jaw. It minimizes stress concentration on drill pipes, facilitating rapid replacement to accommodate varying pipe sizes (φ87~φ203mm) effortlessly.
Anti-loosening device: Featuring a robust mechanical anti-loosening mechanism combined with dual PLC controls, this device ensures that the clamp remains securely in place, eliminating the risk of accidental loosening during operations.

4. Auxiliary function components
Shock absorption system: Our integrated shock absorption system, complete with a specialized spring and guide shaft, efficiently absorbs drill string vibrations, safeguarding the structural integrity of the clamp.
Anti-torque frame: Engineered for optimal stability, this frame delivers anti-torque directly to the Top Drive body through a rigid connection, ensuring consistent and reliable operation.

5. Safety and adaptability design
Retaining wall support structure: This meticulously designed structure prevents lateral displacement and dramatically enhances anti-eccentric load capacity, providing unparalleled stability.
Modular interface: Tailored to seamlessly integrate with leading Top Drive models like TDS11SA, our modular interface supports swift disassembly and assembly, ensuring maximum adaptability.
