6000 ft lb pneumatic torque wrench?

Anyone seen these things?

They've got hydraulic ones that supposedly go up to 58,000 ft lbs. Hand held!!!

I find this extremely hard to believe since my job deals with using power tongs to take things up to 150,000 ft lbs at times.

Doesn't look that amazing to me, especially for a 1-1/2" drive unit with a reaction arm.

Look up torque multipliers.

I want to see the casing your torqueing up to 150,000 ft/lbs

Its usually not casing we take up to 150,000 we have three Rodgers units that we use for R&D on tooling and things like that. casing usually only goes up to 70 or 80k depending on connection and size. Most of its around 30 to 50k though.

I have one at our shop that does something like 12,000 ft lbs. It's a hydraulic handheld wrench that weights over 100 pounds. We were tightening 2.5 inch bolts, with nuts the size of my hand. There were 40 of them, that held the door to a pressure vessel shut while we super heated coal. It's insane.
