CME-55/300 Rubber Track Drill: Remote Control, Versatile and Rugged

Remote control, for remote locations
Remote control track drive allows this machine to climb hills, traverse mud, sand, rocks and snow all while the operator’s feet are planted firmly on the ground. Independent track drive controls, engine speed and carrier front winch are all operated by remote control with emergency back-up manual controls provided. And when you arrive at the site, tool boxes, auger and rod racks, and optional water tank will carry everything you need to get the job done.

Rubber tracks for all site conditions
Steel core reinforced rubber with embedded steel grousers offer durability and climbability, but will not damage pavement. Ground bearing pressure is as low as 4.5 psi (.316 kg/cm²) with optional 18 inch (45.7 cm) wide tracks.

Cummins diesel tier-4 final power unit
A Cummins QSF 3.8 (232 cubic inch) turbocharged 4-cylinder diesel engine provides plenty of power for the CME-55/300 drill and track carrier. Cold weather starting aid and engine protection shutdown systems are standard features.

Drill sliding base, in-out and sideways
Both in-out and sideways slide bases are standard equipment on the CME-55/300 track drill. An 18 inch (45.7 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 6 inch (15.2 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.

The feed system
The hydraulic feed and retract system provides 28,275 pounds (12,826 kg) of retract force and 18,650 pounds (8,460 kg) of down pressure. Twin 72 inch (183 cm) stroke hydraulic feed cylinders are mounted in line with the drill spindle to give you precise control of force on the drilling tools. The split feed slide bushings are easily replaced after normal wear intervals, and the standard upright gives you the clearance to drill with up to 10-1/4 inch hollow augers.

The rotary box

Rugged mechanical rotary drive provides 7,780 foot pounds (10,548 Nm) of torque and rotary speeds of up to 800 rpm. Other rotation and torque combinations are available, including a high-torque rotary drive that gives you up to 9,425 foot pounds (12,778 Nm) of torque and a high-speed rotary drive that gives you up to 665 rpm. The five speed transmission is connected to the drill engine through a heavy-duty 13 inch clutch. With five forward gears and one reverse, there is a rotation speed and torque combination for just about any situation. The mechanical drive system also gives you a better feel for drilling conditions down the hole. It allows you to sense the need for changes in feed pressure and rotational torque.

Control logic ― the key to driller productivity
All drilling and set-up controls are logically arranged on the control panel located at the drillers’ station. 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.

Patented Spindle Brake stops rotation in a instant†
Our emergency Spindle Brake can stop rotation in less than a revolution. The system is activated by two conveniently located push button switches as well as strategically located multi directional wobble switches.

Plenty of tool storage available
The CME-55/300 Carrier comes standard with plenty of auger storage at the front of the carrier without compromising approach angle of the carrier. Two tool boxes are standard, additional boxes are available

55/300 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 up to 6-5/8 inch (16.8 cm) capacity.

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. Other hammer systems available including 170 pound (77 kg), 300 pound (136 kg), and 340 pound (154 kg).

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 drills in-out slide base. This pulls the sockets on the upright drill frame away from the large tapered pins on the mast.

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 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.

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.
