CME-75 Truck Mounted Drill Features

Outstanding Performance and Dependability

Ever wonder why there are so many CME-75 drills out there in the field? It’s really quite simple. With almost 50 years of field experience, the CME-75 has earned a reputation second to none for outstanding performance and dependability.

Cummins diesel power

The CME-75 is powered by a Cummins QSB 4.5 turbo charged diesel engine meeting tier-4 final emissions.

Feed system

Hydraulic feed and retract system provides 30,000 pounds (13,608 kg) of retract force and 20,000 pounds (9,072 kg) of down pressure. The 72 inch (183 cm) stroke, vertical drive system has twin hydraulic cylinders mounted in line with the drill spindle so that pulldown and retract forces are applied directly to the drilling tools. For exceptional drilling efficiency the feed system has two separate controls. One gives you manual control of the feed and retract and the other features detent feed and fast retract positions. Retract rates of up to 95 feet (29 m) per minute let you add or remove drilling tools quickly. Detent feed 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 without changing the settings for the detent feed control.

Control logic — the key to operator productivity

All drilling and set-up controls are logically arranged on the control panel located at the drillers’ station. And the location of all primary controls is the same on all CME drill models so operators can move from one machine to another with confidence. The most commonly used functions, such as the feed, hydraulic hoist, and sliding base levers are staggered for easier identification and operation. Also a lock out position for the clutch lever to prevent accidental engagement.

Rugged mechanical rotary drive provides 10,445 foot pounds (14,160 Nm) of torque, plus high rotation speed when you need it

You get the torque you need for auger drilling, as well as rotation speeds over 745 rpm for rotary or core drilling applications. Other optional rotation speed and torque combinations are also available, including a high-torque rotary drive that gives you 13,225 foot pounds (17,930 Nm) of torque. With five forward gears and one reverse, there’s 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 travel vertically with the spindle, you won’t find yourself unable to change gears when you’re at the top of a feed stroke.

Patented Spindle Brake stops rotation in an 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 strategically located multi-directional wobble switches.
