Model CME-45C - Truck Mounted Auger Drill



Truck, trailer, skid, ATV, tracked carrier, helicopter-portable. The CME-45C can be configured to fit your specific drilling applications.

Hydraulic feed and retract system provides 19,600 lbs. [8,891 kg] of retract force and 13,650 lbs. [6,192 kg] of down pressure.

The 68 inch [173 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.

 Rugged mechanical rotary drive with up to 4,815 foot pounds [6,528 Nm] of torque.

Several torque and rotation speed combinations are available, including a high-speed rotary drive that gives you up to 700 rpm. The four speed transmission is connected to the drill engine through a heavy-duty clutch. With four forward gears and one reverse, there’s a rotation speed and torque combination available for just about any situation. The mechanical rotary drive also gives you a good feel for changes in soil and drilling conditions down the hole. It allows you to sense the need to adjust feed pressure and rotational torque. A torque limiting clutch, which is adjustable, provides protection against shock overload.

Control logic – the key to operator productivity.

All drilling and set-up controls are logically arranged on a control panel located at the drillers station. A lock-out position for the clutch lever helps prevent accidental engagement.

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 by strategically located multi-directional wobble switches.

Automatic SPT 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 safety, all moving parts are enclosed, including the impact area between the weight and the anvil. A 340/140 pound [154/63.5 kg] hammer is also available.

Auger and rod storage

Above deck auger and rod racks are provided with the drill platform.

Several tool box, auger and rod storage configurations are available.

Slide bases make the job easier and quicker.

Slide base options are available in both in-out and sideways movement of the drill on the platform.

A 15 inch [38.1 cm] in-out movement allows you to quickly move the drill on and off the borehole and align the sheaves for lifting tools with the cathead or any of the hoists.

A 8 inch [20.3 cm] sideways movement gives you even more versatility. Aligning augers or rods when making connections is easy. If the bit drifts off at an angle when you start a hole, you can quickly straighten it to a vertical position.

Since the upright and optional mast are mounted directly to the drill frame, they move with the drill when the slide base is used. That means you can drill in any position within a 170 square inch [1097 cm²] area without moving the carrier.

If you have ever tried to line up your rig on an existing bore hole, you’ve probably already recognized another benefit of the slide base.

Angle drilling system for special applications

This unique system allows you to drill holes at various angles between horizontal and vertical. It is especially effective for drilling under 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 rig positioned on an uphill slope. That can eliminate the time consuming job of leveling an area on which to place the rig.

Since the kelly drive is directly connected to the right angle drive box, you can raise and lower the mast with the drivetrain already connected and ready to go.
