Functionality: The TW61 is designed specifically for making up and breaking out drill pipe and drill collars with outside diameters from 4″ to 8 ½″ (102–216 mm)
Torque Capacity:
Make-up Torque: Up to 63,000 ft‑lb (≈ 85,000 Nm)
Break-out Torque: Up to 75,000 ft‑lb (≈ 101,000 Nm)
Hydraulic & Power Requirements:
Hydraulic flow: 30–35 gpm at 2,000 psi (≈ 114–133 L/min at 13,789 kPa)
Air pressure (for the tugger): 90–125 psi (≈ 620–860 kPa)
Weight & Movement:
Weight: Approximately 3,190 lbs (≈ 1,450 kg)
Vertical travel (positioning range): 72″ (≈ 1,830 mm)
Speed: 2″ per second (≈ 50.8 mm/s)
Cycle Timing (at 40 gpm / ~151 L/min):
Clamping both jaws: 2.5 s
Clamping upper jaw: 1.25 s
Torquing (34° rotation): 2 s
Additional Functional Features:
Rotates the tool-joint pin up to 34° to generate the needed torque, while offering its own back-up support.
