Wireline Drilling Core Barrel BQ HQ NQ PQ

Wire-line core drilling tools can lift core from drill rods without picking up coring system.A complete set of wire-line drill tools include:Core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, circle wrench etc.It has some advantages such as high penetration rate, high core recovery ratio, long bit life and lower labour intensity.The advantages can get more clear with the increasing of drill hole depth.

Applications:
 

Excore head assembly

Part of the Excore product solutions, our new line of high performance head assemblies are now available in DCMA size B,N and H, for both surface and pump-in applications. The simple to use, easy to repair and maintain head will provide drillers with what they need to retrieve core, shift after shift. The secure latching and the mechanical piston that locks the core barrel head in the locking coupling is extremely strong and will secure the inner tube within the locking coupling, even in high back pressure bore holes.

Along with a primary landing indication, a secondary latching indication system will let the driller know, not only if he has landed but also if the latches are not fully engaged; signalling that there is a problem in the core barrel and that further actions are needed.

The new Excore head assembly is designed to reduce inventory with its ability to convert from a surface system to a pump-in system for drillers who work in both surface and underground operations. Its improved latching system reduces the chance of mis-latching complications, which will increase productivity and reduce chances of downtime.                   

Excore "Auto Safe" Overshot

We are very proud to offer drilling contractors, with the drilling crews' safety in mind, this innovative and safer overshot; The new Excore series, "Auto Safe" EX Overshot. The safety mechanism of this overshot, unlike competing products, does not require direct intervention from the drilling crew to engage. This means, that the crew cannot forget to engage the safety mechanism as it is automatic and while pulling the inner tube, they do not need to stop the process to retrieve the core. As a result, operators are confident and have peace of mind with one less process to worry about. The simplified process increases the speed of the overall cycle and increases productivity levels.
