SLB Smart Racker.....

Gripper Head 14 inch down to 3 1/2 inch !!

And we thought 6 1/2 inch was "small" !!

Then what' is 2 7/8 in "Optional" used for ? Drilling for a Hydrogen "sniffer" ?

One gripper head that handles all drillpipe, casing, and drill collars from 3 1/2 in to 14 in (2 7/8 in optional); no need to stop and wait to change heads

Accurate soft stabbing function that saves threads on drillpipes

Works in concert with the SmartCat catwalk machine for horizontal-to-vertical operations; no need for overhead V-door machines
