WireLine N Head Assembly (WL N 01.00.00.000) is designed for clamping of inner barrel in outer tube and ensuring of inner tube immobility while drilling.
WireLine N Head Assembly (WL N 01.00.00.000) is designed for clamping of inner barrel in outer tube and ensuring of inner tube immobility while drilling.
Head Assembly consists of:
- upper part of head assembly;
- lower part of head assembly (bearing unit).
Upper part of head assembly enables fixing and lifting of head assembly from borehole, lower part of head assembly enables immobility of inner tube while drilling. Core lifter is designed for separating and lifting of core during extracting of inner tube.
