The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: Harness the power of a dual-cylinder, hydraulic-driven system, where synchronized jaws deliver even pressure for unparalleled drill pipe clamping. Far surpassing traditional single-sided clamping, this innovation ensures unmatched reliability and efficiency.
Floating pin mechanism: Experience the brilliance of a spring-supported floating pin, automatically adjusting to compensate for any displacement deviations during drill pipe threading. This precision-enhancing feature elevates the accuracy of make-up and break-out operations.

2. Hydraulic drive system
Hydraulic cylinder and piston: Experience remarkable precision and efficiency with our state-of-the-art hydraulic system. The solenoid valve expertly directs the flow of the oil circuit, driving the piston with finesse. This motion seamlessly propels the jaw support to extend or retract, flawlessly executing the clamping or release operation.
Sealing technology: Employing cutting-edge sealing technology, we utilize an oil pouring cup with an innovative leak-proof structure and a robust back-clamp sealing pin. This substantially diminishes the risk of hydraulic oil leakage, ensuring optimal performance and longevity.

3. Clamping actuator
Replaceable jaw module: Our meticulously optimized jaw module, validated through rigorous ANSYS static analysis, is crafted to minimize stress concentration on the drill pipe. This design not only enhances durability but also facilitates swift replacement, accommodating drill pipes of varied specifications (φ87~φ203mm) with ease.
Anti-loosening device: Engineered with precision, our advanced mechanical anti-loosening mechanism, coupled with dual PLC control, provides an additional safeguard, preventing any accidental loosening of the clamp during operations. This ensures unwavering reliability and safety.

4. Auxiliary function components
Shock absorption system: Designed to perfection, our integrated shock absorption system, featuring a high-performance spring and guide shaft, adeptly absorbs drill string vibration energy, thereby safeguarding the integrity of the clamp structure and enhancing operational lifespan.
Anti-torque frame: Our anti-torque frame is ingeniously designed to transmit anti-torque forces to the Top Drive body through a robust rigid connection. This ensures steadfast operational stability, maintaining efficiency and safety during operations.

5. Safety and adaptability design
Retaining wall support structure: Engineered for strength, this support structure effectively prevents lateral displacement while bolstering anti-eccentric load capacity, ensuring operational stability.
Modular interface: Seamlessly adapting to a myriad of mainstream Top Drive models, including the esteemed TDS11SA, our modular interface supports swift disassembly and assembly, providing unparalleled convenience and flexibility.
