TWO CME 550X

We have two CME 550X drilling rigs. Each is mounted on a low pressure rubber tire carrier (good for off road drilling. Can angle drill. Set up for wireline bedrock coring, air rotary drilling, mud rotary drilling, and hollow-stem auger drilling. Has a split-tower to allow working in areas with height restrictions. Hydraulic automatic hammer for consistent blow counts.)

Diedrich D25

This rig is a skid-mounted unit. Steel casters can be attached to the skids to move the rig inside of buildings. Minimum working height is 12 feet. Used for geotechnical and environmental drilling with hollow-stem augers and mud rotary methods. Soil sampling methods are performed with an automatic safety hammer or a direct-push hammer. Also used for sediment sampling from barges.

CME 55

On single-axle Chevrolet Kodiak truck (best suited for bridge borings and on-road soil borings. Set up for bedrock coring, mud rotary drilling, and hollow-stem auger drilling).

CME 75

On tandem axle Freightliner truck (best suited for bridge borings, on-road borings, and monitoring well installations. Set up for bedrock coring, mud rotary drilling, and hollow-stem auger drilling). Will drill with up to 10-1/4-inch inside diameter hollow-stem augers.

CME 85

On a tandem axle Peterbilt truck (best suited for deeper soil borings and monitoring well installations). The rig is equipped for drilling with hollow-stem augers, coring of bedrock, and mud and air rotary drilling. Will drill up to 12-1/4-inch inside diameter hollow-stem augers.

CME 95

On tri-axle Mack truck (best suited for air rotary drilling with a tricone bit or down-the-hole hammer, mud rotary drilling with a tricone bit, or hollow-stem augers). Will drill with up to 12-1/4-inch inside diameter hollow-stem augers. We’ve used the rig to install 10-inch diameter double-cased wells, piezometers and monitoring wells into bedrock, and 4-inch diameter steel leachate wells at landfills.

CME 750

On low pressure rubber tire carrier, for off-road drilling. Used for wireline bedrock coring, air rotary drilling, mud rotary drilling, and hollow-stem auger drilling. Will drill with up to 8-1/4-inch inside diameter hollow-stem augers. A cyclone can be mounted on the side of the deck for capturing drilling cuttings when using compressed air drilling into bedrock. Includes 140-pound automatic hammer and 3L8 Moyno water pump.

CME 750X

On low pressure rubber tire carrier with no-spin differentials, for off-road drilling. Used for wireline bedrock coring, air rotary drilling, and hollow-stem auger drilling. Will drill with up to 10-1/4-inch inside diameter hollow-stem augers. With 13,105 foot-pounds of torque, quick-disconnect mast for working in low-clearance areas, and angle drilling capabilities. Includes 140-pound automatic hammer and 3L8 Moyno water pump.

CME 850XR

On 33-inch wide rubber tracks for off-road access, with low center of gravity and low ground bearing pressure. Used for wireline bedrock coring, air rotary drilling, mud rotary drilling, and hollow-stem auger drilling. Will drill with up to 10-1/4-inch inside diameter hollow-stem augers. With 15,100 foot-pounds of torque, quick-disconnect mast for working in low-clearance areas, and angle drilling capabilities. Includes 140-pound automatic hammer and 3L8 Moyno water pump.
