| Power Pack Construction Features | All power packs are skid-mounted and built with serviceability in mind, providing easy walk-around access to daily service points. The narrow profile leaves ample room for on-rack hydraulic hose storage, significantly enhancing general transportability. | |
| Operational Performance & Hydrostatic Drive Train | ||
| Thrust Force | 768,000 lbs (3,416.2 kN) | |
| Pullback Force | 768,000 lbs (3,416.2 kN) | |
| Maximum Spindle Torque | 99,400 ft-lb (134,768.5 Nm) — sustained in Low Gear at maximum engine RPM | |
| Max Spindle Speed (with PS800 Swivel) | 36 rpm @ max engine RPM | |
| Max Spindle Speed (with PS1200/PS1600 Swivels) | 54 rpm @ max engine RPM | |
| Maximum Carriage Travel Speed | 95 ft/min (29 m/min) | |
| Motor Array (Rotation / Carriage) | 1 high-torque single rotation motor / 4 independent carriage drive motors | |
| Mud Swivel Diameter | 3 in (7.6 cm) | |
| High Torque / Low Speed Direct Drive | Utilizes single, through-shaft hydraulic motors (Hagglunds) directly on the rotary and carriage assemblies. This advanced architecture entirely removes bull gears, pinion interfaces, and complex planetary reduction boxes while reducing hydraulic line clutter. | |
| Isolated Hydraulic Circuit Layout | Engineered with strictly independent circuits for rotation, thrust/pullback, and auxiliary loops. Each circuit hooks solely to its own pump stacks and tank cells. In the event of a circuit contamination, damage is safely isolated to that single loop, cutting downtime and maintenance costs. | |
| Heavy-Duty Thrust Bearing Box | Features an oversized internal bearing pack assembly designed to cushion the rotary drive from extreme axial shock loading during high-tonnage pullback operations. | |
| Breakout Vise Systems | ||
| Lower Vise Configuration | Fully enclosed, triple-jaw (3-jaw) clamp, 8 in (20.3 cm) block profile | |
| Lower Vise Breakout Force | 253,000 ft-lb (343,022.5 Nm) | |
| Lower Vise Travel & Net Weight | Travel Distance: 6 ft (1.8 m) | Net Weight: 3,800 lbs (1,723.7 kg) | |
| Lower Vise Inside Diameter | 9.8 in (24.9 cm) | |
| Lower Vise Service Adaptability | Equipped with easily replaceable dies and variable jaw blocks. Can be completely detached via two structural pins and six hydraulic quick-disconnect couplings to easily accommodate diverse drill pipe ranges and casing jobs. | |
| Upper Vise Configuration | Floating carriage-integrated upper vise, 2-jaw clamp layout (Standard Equipment) | |
| Upper Vise Clamp Force | 250,000 ft-lb (338,955 Nm) | |
| Upper Vise Inside Diameter | 10 in (25.4 cm) | |
| Upper Vise Performance Advantage | Grips the drill stem right in front of the quill/drive shaft, preventing dangerous rod wrap or windup when breaking out the upper joint. The integrated float prevents thread binding during joint make-up, while saving extensive carriage travel cycle times. | |
| Driller Cabin, Safety Loops & Loop Filtration | ||
| Driller Operator Station (Cabin) | Dimensions: 10 ft x 8.5 ft x 9 ft (3.1 m x 2.6 m x 2.7 m) | Weight: 6,000 lbs (2,721.6 kg). Equipped with a heavy-duty in-wall combination heating and air conditioning climate control unit. | |
| Safety Array Compliance | Long-Range Remote Lockout System: Yes | Electronic Strike Alert Safety Monitoring: Yes | |
| High-Pressure Bi-Directional Filtration | The closed hydrostatic circuit relies on high-pressure bi-directional loop filters to aggressively harvest micro-contaminants, preventing premature wear on the premium Sauer-Danfoss pumps and motors. | |
| Hydraulic Control Simplification | Vermeer employs a simplified hydraulic layout backed up by direct manual override controls, optimizing onsite troubleshooting and field diagnostics. | |
