Ever wonder why there are so many CME-75 drills out there in the field? It’s really quite simple. With over 20 years of field experience, the CME-75 has earned a reputation second to none for outstanding performance and dependability.
Hydraulic feed and retract system provides 30,000 pounds [13,607 kg] of retract force and 20,000 pounds [9,071 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.
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 78 feet [24 m] per minute let you add or remove drilling tools quickly. 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 without changing the pressure settings for the detent feed control.
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.
Rugged mechanical rotary drive provides 10,230 foot pounds [13,870 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 740 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 12,950 foot pounds [17,557 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. A torque limiting clutch provides protection against shock overload.
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.
