BOU NOU HOU Wireline Core Barrel Underground Drilling Core Barrel Head Assembly Overshot

Underground Head Assembly features dual lip seals and a pump-in valve for faster tripping times and positive latch indication; the location of the lip seals prevents in ground fluid or gas pressure from releasing the latches and eliminates the need for drive keys or tangs to keep the head spinning with the rods.

The head assembly also features the head spearpoint for easier unloading of the inner tube in tight spaces, and the new retracting case allows loading of the head assembly into the rods without a loading sleeve.

1. spearhead assembly for added strength and safety features self-lubricating nylon to reduce wear, self-centering spearpoint with multiple detent positions, and an innovative design to eliminate pinch points.

2. Unique hold-back brake retains inner-tube assemblies in the drill string for safer operations in inclined and up-angle holes, as well as optional two-handed latch retraction for use without loading sleeves.

3. Roller Latches allow greater pump-in speed and productivity with diminished wear. The self-locking Roller Latch eliminates the need for adapter couplings and utilizes a newly-designed locking coupling.

4.Fluid flow and utilizes corrosion and wear-resistant components to ensure smooth and reliable functionality while offering less resistance in all hole angles

5. Roller Latch head assemblies are safer and more reliable in underground applications, which allows drillers to maximize productivity.
