The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: This innovative dual-cylinder mechanism ensures a symphonious clamping action, surpassing traditional methods with its unparalleled efficiency and reliability. Experience the future of drill pipe handling with this balanced clamping technology.
Floating pin mechanism: Equipped with a spring-supported floating pin, this mechanism automatically adjusts for any displacement deviations when threading the drill pipe, providing unmatched precision in make-up and breakout tasks.

2. Hydraulic drive system
Hydraulic cylinder and piston: Masterfully controlled by a solenoid valve, this system directs the oil circuit to maneuver the piston, enabling seamless extension and retraction of the jaw support, culminating in flawless clamping and release operations.
Sealing Technology: Experience leak-proof assurance with our innovative oil pouring cup structure and back-clamp sealing pin. This advanced design significantly reduces the risk of hydraulic oil leakage, ensuring your operations remain smooth and uninterrupted.

3. Clamping Actuator
Replaceable Jaw Module: Our cutting-edge jaw module has been optimized through ANSYS static analysis, effectively minimizing stress concentration on drill pipes. Easily adaptable, this module supports swift replacement for compatibility with drill pipe specifications ranging from φ87 to φ203mm.
Anti-Loosening Device: Engineered with a robust mechanical anti-loosening mechanism and dual PLC control, our device ensures the clamp remains firmly secure, preventing any accidental loosening during rigorous operations.

4. Auxiliary Function Components
Shock Absorption System: Our integrated system combines a shock absorption spring with a guide shaft, expertly absorbing drill string vibrations. This not only protects the clamp structure but also enhances overall operational durability.
Anti-Torque Frame: Designed for excellence, the frame transmits anti-torque to the Top Drive body through a sturdy rigid connection, guaranteeing unparalleled operational stability.

5. Safety and Adaptability Design
Retaining Wall Support Structure: Specifically crafted to prevent lateral displacement, it significantly boosts anti-eccentric load capacity, ensuring your operations proceed without a hitch.
Modular Interface: Seamlessly integrates with mainstream Top Drive models like the TDS11SA. Enjoy the convenience of quick disassembly and assembly, adding efficiency to your operations.
