PEERCHEER offers BQ NQ HQ PQ BWL NWL HWL PWL core lifter for use with BQ NQ HQ PQ core barrels. The BQ NQ HQ PQ core lifter is a hardened steel, split collar with a tapered body that mates to a tapered socket in the BQ NQ HQ PQ 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. Q series core lifters are available for application in standard DCDMA B N H P size.
PEERCHEER’S core lifters are made out of high-quality alloy steel that has been heat treated to increase strength, toughness, and wear life.
