The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: Embrace the future with our hydraulically driven dual-cylinder system that synchronously advances the jaws, achieving unparalleled balanced clamping of drill pipes. This innovation surpasses traditional single-sided clamping, offering enhanced efficiency and reliability.
Floating pin mechanism: The spring-supported floating pin ingeniously compensates for displacement deviations during drill pipe threading, ensuring superior accuracy in both make-up and break-out operations.

2. Hydraulic drive system
Hydraulic cylinder and piston: Masterfully controlled by a solenoid valve, the oil circuit direction is precisely managed, empowering the piston to effectively drive the jaw support for seamless extension and retraction, culminating in flawless clamping and release actions.
Sealing Technology: Experience the pinnacle of oil containment with our cutting-edge oil pouring cup leak-proof structure, coupled with a precision-engineered back-clamp sealing pin. This superior design significantly minimizes the risk of hydraulic oil leakage, ensuring optimal performance and safety.

3. Clamping Actuator
Replaceable Jaw Module: Discover the innovation of our optimized jaw, meticulously verified through ANSYS static analysis. This advanced design reduces stress concentration on the drill pipe, facilitating rapid jaw replacement, and caters to a diverse range of drill pipe specifications (φ87~φ203mm) with unmatched efficiency.
Anti-Loosening Device: Our state-of-the-art mechanical anti-loosening mechanism, paired with dual PLC control, ensures unwavering security by preventing accidental clamp release during operations, providing you peace of mind and operational integrity.

4. Auxiliary Function Components
Shock Absorption System: Featuring an integrated shock absorption spring and a guide shaft, this system effectively dissipates vibration energy from the drill string, offering enhanced protection to the clamp structure and extending its durability.
Anti-Torque Frame: With its robust rigid connection, our anti-torque frame proficiently transfers anti-torque to the Top Drive body, guaranteeing stable and reliable operational performance.

5. Safety and Adaptability Design
Retaining Wall Support Structure: Specifically designed to prevent lateral displacement, this structure significantly amplifies the anti-eccentric load capacity, ensuring steadfast stability during operation.
Modular Interface: Engineered to seamlessly integrate with mainstream Top Drive models, including TDS11SA, our interface supports quick disassembly and assembly, enhancing operational flexibility and efficiency.
