API Certificated High Quality Lifting Sub
Description:
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.
Details:
Lifting Subs are of one-piece construction and manufactured from alloy steel. The Lifting Sub comes as tapered or square shoulder types and is available in all diameters and lengths.
A lift sub enables the safe, effective and efficient handling of straight OD tubulars such as drill collars, shock tools, directional equipment jars, and other tools using the drill pipe elevators. All of our lift subs are manufactured in accordance with API specifications.
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.
