CME-75 Truck Mounted Drill: Reliable Performance for Any Job

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.

75 Optional Equipment

Hydraulic rod holder and breakout wrench
The hydraulic rod holder makes your job quicker and safer. It not only pivots from on-hole to off-hole positions, but also hydraulically moves in and out. For efficient operation, the breakout wrench is mounted at the pivot point of the rod holder arm. Systems available for up to 6 5/8 inch diameter pipe. Adjustable height is also available.

Automatic hammer
Our 140 pound (63.5 kg) automatic hammer gives you extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586 requirements. That’s because there are no ropes or cables to impede the free fall of the weight. The hammer swings from stored position to on-hole position. Since raising and lowering is done hydraulically, set up is quick and almost effortless. For maximum saftey, all moving parts are enclosed, including the impact area between the weight and the anvil. Auto hammer systems also available with 170 pound (77.1 kg), 300 pound (136.1 kg), and 340 pound (154.2 kg) weights.

Quick mast disconnect
This feature allows you to quickly disconnect the mast when working inside buildings, underneath bridges or in other low overhead drilling locations. Since the mast is completely separated from the upright, it doesn’t interfere with other drill functions such as the in-out slide base. With the mast in the horizontal position, you simply clamp it to its storage rack and extend the drill’s in-out slide base. This pulls the sockets on the upright drill frame away from the large tapered pins on the mast.

Patented angle drilling system
This unique system is especially effective for drilling underneath ponds, storage tanks, or other structures. When used with our patented continuous sample tube system, you can even take soil samples while drilling angle holes. The angle drilling system will also allow you to drill vertically with the carrier positioned on an uphill slope. That can eliminate the time-consuming job of leveling the rig. And, since the kelly drive is always coupled to the right angle drive box, you can raise and lower the mast with the drivetrain already connected and ready to go.

Fluted kelly and chuck assembly
If your drilling operations include a substantial amount of rotary or core drilling, the CME fluted kelly and chuck assembly can save you a lot of time. The 5 foot (1.5 m) stroke of the kelly combined with the 6 foot (1.8 m) stroke of the feed system, gives you a total stroke of 11 feet (3.4 m). You can use 10 foot (3 m) drill rods, which means fewer rod connections and less rod handling. The kelly has two vertical slots (flutes) and two sets of horizontal slots which are engaged by the chuck to provide rotary torque and thrust. The CME fluted kelly can even be rotated without engaging the thrust keys. This gives you the option of using the weight of the drill string to provide down pressure on the bit. The 2 5/8 inch (6.7 cm) fluted kelly and chuck assembly is available in either manual or hydraulic actuated configurations. Or if you are drilling larger diameter holes, a 3 1/2 inch (8.9 cm) O.D. fluted kelly and hydraulic chuck assembly is available.

Cone Penetrometer Testing (CPT)
CPT controls allow you to easily switch from typical geotechnical drilling and sampling procedures to pushing a cone. A dedicated hydraulic circuit including detented CPT control lever, hydraulic down feed pressure and CPT feed rate controls provide precise pressure and penetration adjustments required to meet ASTM standards. A separate CPT system hydraulic pressure gauge is provided as well. Anchor points are installed below the drill feed frame so that maximum available pressure can be applied to the CPT tools. A 12-volt power source can be provided at the drill control panel to accommodate electronic devices associated with CPT procedures. Mounting for depth transducers or other related equipment can also be provided.
