API Standard Oil Drilling Tools Lift Sub 


Features

Lift subs are used to lift BHA components such as drilling motors, jars, shock tools, drill collars, etc. from the catwalk to the rig floor. Lift subs are simply screwed to the top of the tool and feature an elevator groove, engineered to API specifications, that the rig uses to pick up the tool.

Lifting Subs are of one-piece construction and manufactured from alloy steel fully heat-treated. The structure includes sloping shoulder and straight shoulder, which can be selected by customs. Lifting Subs are normally manufactured 1200mm long overall. But this type sub can be made to any length desired.
