Hydraulic
B46
The most practical multi-purpose under-CDL drilling rig on the market, engineered for maximum uptime and effortless mobility. Whether you're performing geotechnical exploration, environmental sampling, or asphalt coring, this rig is built to perform.
The heavy-duty 4-speed hydraulic top head delivers an impressive 5,417 ft-lbs of torque in low gear and over 700 RPM in high gear, giving operators the power and versatility needed across a wide range of applications.
Its true added value lies in borehole accessibility. The in-and-out slide base allows operators to efficiently utilize hoists and the automatic hammer, providing smooth, unobstructed access during operations. This design enables seamless integration of hydraulic top head capability into an existing mechanical drill fleet—expanding functionality without disrupting established workflows.
Built for productivity, designed for flexibility, and optimized for the field.
