NMLC Core Lifter Case for Core Barrel NMLC Triple Tube Core barrel

NMLC Core Lifter Case for Core Barrel

ROSCHEN offers NMLC HMLC core lifter for use with NMLC HMLC core barrels. The NMLC HMLC core lifter is a hardened steel, split collar with a tapered body that mates to a tapered socket in the NMLC HMLC core lifter case. In a core breaking operation, the drill string is lifted off bottom and the core sample begins to slide out of the inner-tube. Grip features on the inner surface of the core lifter catch the moving core sample and pull the core lifter towards the smaller end of the tapered socket in the core lifter case. The core lifter is constricted against the core sample and retains it after it has broken, allowing retrieval to surface. MLC series core lifters are available for application in DCDMA N H size.

ROSCHEN'S core lifters are made out of high-quality alloy steel that has been heat treated to increase strength, toughness, and wear life.
