Features | Specifications | Optional Equipment

When the CME-55 first rolled of 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 35 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 feed system

CME-55 Feed SystemThe 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, hydraulic vertical drive system has no chains or cables which can stretch. It gives 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 7,700 foot pounds [10,440 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 9,400 foot pounds [12,744 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.

CME-55 Control Panel

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

CME-55 Spindle Brake E-Stop SystemOur 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 box combinations

Numerous tool box, water tank, auger and rod storage configurations are available
