The core components and functions:
1. Clamp body structure
Dual-cylinder clamp design: Our system leverages hydraulically driven dual cylinders to synchronize jaw movement, ensuring balanced, efficient, and reliable drill pipe clamping-a leap beyond traditional single-sided methods.
Floating pin mechanism: Springs support the floating pin, automatically compensating for displacement deviations during thread engagement. Enhanced make-up and break-out precision at your fingertips.

2. Hydraulic drive system
Hydraulic cylinder and piston: Solenoid valves deftly manage oil circuit directions, driving pistons that extend and retract jaw supports. Perfect clamping and release actions are achieved with ease and precision.
Sealing technology: Embark on a journey of innovation with our cutting-edge oil pouring cup leak-proof design. Our expertly crafted back-clamp sealing pin dramatically reduces the risk of hydraulic oil leakage, ensuring seamless and safe operations every time.

3. Clamping actuator: Experience unparalleled precision and reliability with our state-of-the-art clamping actuator, engineered to deliver exceptional performance.
Replaceable jaw module: Our expertly optimized jaw module, verified through rigorous ANSYS static analysis, ingeniously reduces stress concentration on the drill pipe. This revolutionary design supports rapid replacement, effortlessly adapting to drill pipes of varying specifications (φ87~φ203mm), thereby enhancing operational efficiency.
Anti-loosening device: Our advanced mechanical anti-loosening mechanism, coupled with dual PLC control, provides an unwavering safeguard against accidental clamp loosening during operation, elevating safety to new heights.

4. Auxiliary function components: Enhance your operations with our auxiliary function components, designed to provide outstanding performance and adaptability.
Shock absorption system: Our pioneering shock absorption system ingeniously integrates a spring and guide shaft to adeptly absorb drill string vibration energy, thereby protecting the clamp structure and extending its longevity.
Anti-torque frame: With precision engineering, our anti-torque frame transmits anti-torque to the Top Drive body via a robust rigid connection, ensuring operational stability and consistent performance.

5. Safety and adaptability design: Meticulously crafted with safety and adaptability at the forefront, ensuring optimal performance under diverse conditions.
Retaining wall support structure: Our innovative retaining wall support structure prevents lateral displacement, significantly enhancing anti-eccentric load capacity for superior stability.
Modular interface: Seamlessly adapt to mainstream Top Drive models, including TDS11SA, with our cutting-edge modular interface that supports swift disassembly and assembly, optimizing efficiency.
