The core lifter and core lifter case are responsible for gripping and holding the core sample during extraction. The core lifter, typically made of hardened spring steel, fits inside the core lifter case and compresses around the core sample when upward pressure is applied.
This mechanism ensures the core doesn't fall out when the inner tube is pulled to the surface. YKDrill offers a range of core lifters optimized for different diameters and rock conditions.
Proper matching between core lifter, case, and core bit is essential. A mismatch can result in core loss or jamming. Routine checks for wear and deformation can help maintain high core recovery rates.
