CME-55 Trailer Mounted Auger Drilling Rig


The trailer mounted CME-55 is just another variation of the drill that has been the standard of its class for more than 60 years. The popularity and high resale value of this classic machine bear testimony to its performance record in the field. With 28,275 pounds (12,825 kg) of retract force and up to 9,425 foot pounds (12,778 Nm) of rotary torque, the CME-55 is capable of drilling holes up to 14 inches (36 cm) in diameter using hollow stem augers.

CME-55LC Trailer Mounted Auger Drill Rig


The CME-55LC with its unique feed and retract system can also be mounted on the CME-55T trailer. The quick disconnect mast and low clearance sheaves allow you to work under service station canopies, bridges or other overhead restrictions with the power and productivity of a full-sized CME-55. The optional SPT hammer even has a separate valve for lifting the hammer when working in the low clearance mode that restricts the height that the hammer can be raised.

The CME-55LCX offers easy low clearance conversion, just like the CME-55LC but also goes to the next level in power. A Cummins tier-4f power unit with 130 horsepower delivers nearly 12,000 foot pounds (16,200 Nm) of torque to the drill spindle.
