The workhouse of the HSA market, the CME-55 has capabilities that get the job done in an efficient and cost effective manner. The hydraulic feed and retract system provides 28,275 lbs. [12,826 kg] of retract force and 18,650 lbs. [8,460 kg] of down pressure. The 72 inch [183 cm] stroke, hydraulic vertical drive system has no chains or cables which can stretch. It gives you precise control of force on the drilling tools. From 2.25” HSA to 10.25” HSA, the CME can get the job done. Both of our CME-55 rigs have 140# automatic drop hammers for SPT.
