When the CME-55 first rolled off the production line back in 1963, it was an immediate success. It had the power, versatility, and dependability to handle geotechnical and medium-sized environmental jobs with maximum efficiency. Although today’s CME-55 features many refinements, it’s basically the same drill that has been the standard of its class for more than 60 years. The popularity and the high resale value of this classic machine bear testimony to its performance record in the field. The CME-55 can be mounted on a variety of different carriers, including two wheel or all-wheel drive, single or tandem axle trucks. It can also be mounted on the CME-55T trailer or on the CME-300 tracked carrier.
The CME-55 drill is powered by a Cummins QSF 3.8 turbo charged diesel engine meeting tier-4 final emissions.
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. 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. The split slide bushings for the feed cylinders are easily replaced after normal wear intervals, and the standard upright gives you the clearance to drill with up to 10 1/4 inch ID hollow augers.
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.
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.
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.
CME drills are surrounded by the equipment necessary for a productive and efficient operation. Drill platforms include numerous tool boxes, auger and rod racks, work tables and tool storage hooks. Several water pumps are available to accommodate rotary and core drilling operations. Water tank options include steel, stainless steel, and poly construction and can be combined with tool boxes, rod racks and open storage to take full advantage of available deck space.
