Core Lifter Case – Secure Housing for Core Lifters in Wireline Drilling
Reliable and Durable Core Lifter Case for Efficient Core Recovery
Built for Mineral Exploration, Geotechnical Drilling, and Core Sampling Operations
✅ Product Overview:
The Core Lifter Case is a precision-engineered component in the wireline core barrel system, designed to house and support the core lifter during the core recovery process. Located at the bottom of the inner tube assembly, the core lifter case ensures that the core lifter functions properly by holding it in the correct position to grip and retain the core sample as the inner tube is retrieved to the surface.
This essential part is widely used in mineral exploration, geotechnical investigations, and environmental core sampling, where maximum core recovery and minimal core loss are critical.
When it’s time to break the core sample, the core lifter case plays a crucial role.
Its tapered interior prevents the core lifter from shifting, ensuring it maintains its grip on the core sample.
