Nq3 Hq3 Pq3 Wire Line Triple Tube Core Barrels for Geology Geotechnical Investigation/Mining Exploration

Wireline core drilling is a kind of don't need to lift the drill rod, direct gain rock cores drilling tool. It includes: core barrels assembly, overshot, drill rods, wireline winch, hoist plug, foot clamp, circular wrenches and other accessories. It has high drilling efficiency, high bit coring rate, long working life, low labor intensity. With the more deep drilling depth, its advantage is more obvious.

The head assembly provides: latching and pivoting spearpoint mechanisms to allow insertion and retrieval of the inner tube assembly, a bearing assembly to allow the inner tube to remain stationary and avoid sample damage while drilling, fluid pressure operating indications and fluid control valves.

All head assemblies incorporate a shut off valve assembly which provides a fluid pressure signal to the drill operator when the valve members are compressed, indicating a full or blocked inner tube.

Our head assembly features long life span, good compatibility with parts like inner tube and outer tube from other vendors, and availability in all spare parts.

All With ISO certificate & quality control.
