This Drill Means Business
You can take on the biggest jobs with confidence, which means more business for you. Whether it’s a large diameter auger hole, or deep rotary job, no other rig is going to get it done faster or more efficiently than the CME-95. Day after day… year after year. That’s because this rig was designed from the ground up for the toughest jobs. It’s not only powerful, it’s rugged. The right angle drive… the rotary box… the frame… everything is massive. This rig is engineered to handle the forces it produces… and more.
You get the torque you need for turning large diameter augers, as well as rotation speeds over 544 rpm for rotary or core drill applications. Other optional rotation speed and torque combinations are available to meet your specific drilling needs. The power shift transmission features hydraulically actuated clutches and torque converter that provides shock overload protection. With four gears in both forward and reverse, there is a rotation speed and torque combination available for any situation.
Low speed drive system makes lining up auger connections easy.
This independent, hydraulically actuated system gives you infinite regulation of spindle rotation from 0 to 100 rpm with up to 9,400 ft lbs. [12,745 Nm] of torque. It is especially beneficial when lining up auger connections. It also works exceptionally well in down-the-hole hammer drilling applications.
Our emergency spindle brake can stop rotation in less than a revolution. This system is activated by two conveniently located push button switches, as well as by strategically located, multi-directional wobble switches.
Hydraulic feed and retract system provides 62,830 ft lbs. [28,500 Nm] of retract force and 33,135 lbs. [15,030 Nm] of down pressure.
The CME 95 has plenty of retract power for pulling heavy strings of augers. And the vertical drive 75 inch [1.9 m] stroke hydraulic drive system has no chains or cables which can stretch, which gives you precise control of force on the drilling tools. For exceptional drilling efficiency, the feed system has two separate feed controls. After you set the first lever for drilling feed rate and pressure, it will not be affected by changes in engine rpm or formation resistance (until pre-set down pressure is reached). The second feed lever is used for rapid retract when adding rods or augers. Retract rates of up to 96 ft [26 m] per minute are available without changing the setting of the first feed lever.
Control logic. A key to productivity.
Drilling and setup controls are logically arranged on a control panel at the drillers’ station. The most frequently used controls, such as the feed, hydraulic hoists, and sliding base, are staggered for easier identification and operation.
This system makes coupling and uncoupling the kelly bar to the right angle drive virtually effortless. After raising the mast into place, the kelly bar is hydraulically lowered until the flex coupling engages the right angle drive. An interlock system is furnished that will not allow lowering of the mast until the kelly is hydraulically raised and disconnected from the right angle drive.
Slide bases make the job easier and quicker.
A 20 inch [50.8 cm] in-out movement allows you to quickly move the drill off the borehole and align the sheaves for lifting tools with the cathead or any of the hoists. An 8 inch [20.3 cm] sideways movement gives you even more versatility. Aligning augers or rods when making connections is easy, or if a bit drifts off at an angle when you start a hole, you can quickly straighten it to a vertical position. If you have ever tried to line up your rig to an existing borehole, you’ve probably already recognized another benefit of the slide bases.
The standard hydraulic hoist is controlled by a single lever, conveniently located at the drillers’ station. Fast line speeds of 119 ft [36 m] per minute up and 517 ft [157 m] per minute down give you excellent hoisting efficiency.
