Hydraulic Make-up & Breakout Machine (Bucking Unit) - High Precision Torque Solutions from China Suppliers and Factory
Features of machine
Our Digital Hydraulic Make-up&Breakout Unit integrates high-precision torque testing sensors to enable ±1% accuracy in spinner torque control. This digital feedback system dynamically adjusts hydraulic pressure to maintain specified torque values, eliminating over-tightening risks in make-up/breakout operations.
Equipped with high-torque spinner motors, the unit achieves:
50% faster make-up/breakout cycles compared to conventional systems.
Continuous operation at 90% rated torque without performance degradation.
Automatic speed adjustment based on pipe diameter.
There are three models:
| Model | Pipe Size Range |
|---|---|
| TKL-MB-1 | 60.3–177.8 mm (2⅜"–7") |
| TKL-MB-2 | 177.8–340 mm (7"–13.38") |
| TKL-MB-3 | 340–508 mm (13.38"–20") |
