CME-55LC Low Clearance Trailer Mounted Drill: Compact Power for Tight Spaces

Hydraulic feed system for low overhead clearance
CME-55LC Trailer Mounted DrillThe unique feed system of the CME-55LC drill provides a full 72 inch stroke without hydraulic cylinders that normally extend above the feed frame of the drill. The hydraulic feed system provides 27,615 pounds (12,526 kg) of retract force and 19,750 pounds (8,959 kg) of down pressure. 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 inside diameter hollow stem augers.

Quick disconnect mast
The quick disconnect mast can be secured in its storage rack and removed from the drill by simply sliding the drill back with the hydraulic in/out slide base control. “Quick-cabling” sheaves allow you to easily move the hoist lines from the mast sheaves to the low clearance sheaves provided above the drill frame.

Cummins diesel power
The CME-55LC is powered by a Cummins QSF 3.8 turbocharged diesel engine meeting tier-4 final emissions standards. Cold weather starting aid and engine protection shutdown systems are standard equipment.

Mechanical rotary drive
Rugged mechanical standard 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 rotary speeds of 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
CME-55LC Trailer Mounted DrillAll drilling and set-up controls are logically arranged on the control panel located at the driller’s 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 an 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.

Tool storage
The CME-55T trailer is designed specifically for CME-55 drills which means best possible weight distribution and use of available space. Four tool boxes provide plenty of storage. Tool boxes are mounted forward to help distribute the weight evenly on the trailer. Drill rod and auger rack are mounted over the fenders on both sides of the CME-55T trailer.

Leveling system
The CME-55T trailer is equipped with three hydraulic leveling jacks. Two jacks are mounted at the rear and a third is at the front. The 36-stroke jack cylinders make it easy to level the rig regardless of the site conditions.

55LC Optional Equipment

Hydraulic rod holder and breakout wrench
The CME hydraulic rod holder/break-out wrench system 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 easy alignment with the tools. Jaws are specific to rod diameter applying even pressure and preventing damage to drill rods or casing. For efficient operation, the breakout wrench is mounted at the pivot point of the rod holder arm.

Slide bases make the job easier and quicker
Slide base options are available for both in-out and sideways movement of the drill on the platform. Aligning the augers or rods when making connections is easy, or if the bit drifts off at an angle when starting 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.

Automatic SPT hammer
The CME-140 pound (63.5 kg) automatic SPT hammer system gives you extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586 requirements. 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 are available including 170 pound (77 kg), 300 pound (136 kg), and 340 pound (154 kg).

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.
