FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to handling tube elements in drilling the wells. Tube handling tool comprises preloading element to apply axial force and actuating mechanism to produce axial force, tool coupler to engage actuating mechanism with tube handling tool, and tube coupler to transfer axial force produced by actuating mechanism, slotted element with multiple long slots extending in some direction, element with recesses articulated with slotted element and having multiple recesses each tapered in direction from shallow end to deep end, and multiple rolling elements each extending through one of said slots provided location in shallow end of one of said multiple slots, and pulled inside slotted element provided location in deep end. Note here that, at least, portion of axial force is transferred via tube element to, at least portion of multiple rolling elements.
EFFECT: reliable operation, proper joint with tubes.
