CME-85

Feel the power

Mechanical rotary drive gives you 21,366 foot pounds [28,968 Nm] of torque, plus high rotation when you need it.

You get the torque you need for turning large diameter augers, as well as rotation speeds over 465 rpm for rotary or core drilling applications. Other optional rotation speed and torque combinations are also available for your specific drilling applications. With five forward gears and one reverse, there is a rotation speed and torque combination available for just about any situation. The transmission is connected to the drill engine through a heavy-duty 13 inch [33 cm] clutch. And since the transmission does not move vertically with the spindle, you won't find yourself unable to change gears when you are at the top of the feed stroke. A torque limiting clutch also provides protection against shock overload and is adjustable by turning a single nut.

Patented spindle brake stops rotation in a instant.

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 48,000 pounds [21,772 kg] of retract force and 28,000 pounds [12,700 kg] of down pressure.
The CME-85 has plenty of retract power for pulling heavy strings of augers. And the 75 inch stroke, hydraulic vertical drive system has no chains or cables which can stretch. It gives you precise control of force on the drilling tools. For exceptional drilling efficiency the feed system has two separate controls. One gives you manual control of feed and retract and features both normal and fast retract positions. Retract rates of up to 95 feet [29 m] per minute let you add or remove drilling tools quickly. The other is exclusively for feed and has a detent engaged position. Pressure controls let you dial in a specific feed rate and pressure. This system is extremely advantageous in core drilling and other operations that require precise control of feed. And since the two controls are isolated, you can use the manual control for rapid retract without changing the pressure settings for the detent feed control.

Control logic - the key to operator productivity.

Drilling and setup controls are logically arranged on a control panel at the driller's station. The most frequently used controls, such as feed, hydraulic hoists, and sliding base levers, are staggered for easier identification and operation.

Patented hydraulic kelly bar lifting system for quick and easy set-up.

Coupling and uncoupling the kelly bar to the right angle drive is virtually effortless. After raising the mast, the kelly bar is lowered until the flex coupling engages the right angle drive output shaft. An interlock system is furnished that will not allow the lowering of the mast until the kelly bar is hydraulically raised and disconnected from 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. A 10 inch [25.4 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.

10,000 pound [4,535.9 kg] hydraulic hoist for big lifting jobs.

The standard hydraulic hoist is controlled by a single lever, conveniently located at the drillers' station. Fast line speeds of 72 ft [21 m] per minute up and 310 ft [94 m] per minute down give you excellent hoisting efficiency.
