CME 55LCX – Your Powerful, Low-Clearance Drill Rig

The only drill rig of its kind, the CME 55LCX rubber-track drill rig has the torque and power of a CME 75 with a working height of just 12 feet. This is the only rig in existence of this size, with this power. Capable of both mud rotary and hollow stem auger drilling, the 55LCX features a 140 pound auto-hammer for extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586 requirements; perfect for geotechnical and environmental projects. This low clearance, compact, track-mounted rig will drill where truck-mounted rigs won’t fit: under canopies and low bridges, below low-hanging power lines, on bluffs and in rough terrain.
