PEERCHEER offers NQ3 HQ3 PQ3 core lifter case for use with NQ3 HQ3 PQ3 core barrels. The NQ3 HQ3 PQ3 core lifter case mates to the inner-tube and houses the core lifter in a tapered socket which controls movement of the NQ3 HQ3 PQ3 core lifter. As the drill string is lifted during a core breaking operation, the core lifter case bottoms out on the inside of the drill bit transferring the pullback load from the drill string to the core lifter until the core sample breaks. Q3 series ore lifter cases are available for application in standard DCDMA N H P size.
PEERCHEER’S core lifters are made of a high-quality alloy steel that is specially heat treated to increase strength,toughness, and wear life.
