The CME-850 is a high-capacity track-mounted rig designed for rigorous geotechnical and environmental drilling in tough terrains. Built on heavy-duty crawler tracks, it offers the strength of an 85-series machine with low ground-bearing pressure. Engineered for wetland conditions, steep slopes, and soft sands, it outperforms conventional truck-mounted rigs. Featuring the CME-850 highlights our dedication to providing engineers with superior off-road capabilities for demanding industrial drilling projects.
Engine Type: Deutz 6-Cylinder Turbocharged Heavy-Duty Diesel Engine (or high-output Cummins diesel configuration).
Power Output: Rated up to 197 Horsepower for sustained heavy drilling loads.
Fuel Capacity: Integrated 60-Gallon high-capacity fuel tank for long, continuous remote field operations.
Top Head Rotation (Schramm), Mast & Feed System (Pullback/Pulldown), Compressor (Sullair 1350 cfm).
Carrier Configuration: Heavy-duty integrated rubber or steel crawler track design measuring approximately 8.5 feet wide by 19 feet long.
Total Rig Weight: Approximately 24,000 to 30,000 lbs fully tooled.
Mast Working Height: Rises to 26 feet up to the crown sheaves when fully extended; folds cleanly down to under 8 feet for seamless shipping clearance.
Ground Bearing Pressure: Delivers an incredibly low footprint of only 2.5 psi, minimizing site environmental damage and allowing access to delicate wetlands or soft sands.
Patented Spindle Brake System: Outfitted with an emergency mechanical spindle brake that halts rig rotation instantly in less than one revolution via wobble-switches and dual safety push-buttons.
Chassis Stabilization: Features a 3-jack high-stroke structural hydraulic leveling system to achieve complete leveling on extreme slopes or soft, uneven grades.
Maximum Retract Force: Massive 28,275 lbs of hydraulic pulling power to smoothly pull out deep casing columns and locked tool strings.
Pulldown Force: Delivers a steady vertical down pressure of 18,650 lbs to slice through dense bedrock or compacted gravels.
Cylinder Feed Layout: Long-stroke twin vertical feed cylinders engineered directly in-line with the mechanical drive spindle for uniform force distribution.
Automatic SPT Hammer: Equipped with an ASTM D-1586 standard 140 lb. hydraulic self-compensating automatic hammer for exact, automated geotechnical penetration testing.
Onboard Storage Deck: Features heavy-duty integrated underbody toolboxes, high-capacity side drill rod racks, and dedicated auger racks across an 8,800 sq. inch all-terrain work area.
Fluid Delivery Support: Fully integrated with a high-durability Moyno water/mud injection pump system and onboard water supply tanks for active borehole clearing.
