I have to admit, I’m not entirely sure how these work, but they look like something from the end of Inspector Gadget’s forearm. They’re for precisely torquing large bolts in tight spaces, apparently mounting on the end of a long handle and accepting hydraulic feed and return lines. Unless I miss my guess, an internal pressure regulator determines how much torque is exerted.
If anyone’s ever used one of these, what are they like? The baddest torque tool I’ve ever used was a 3/4″-drive impact wrench, which is probably a pushover compared to these suckers.
Since the application is scarce, so are these tools. As far as I can find, no online retailer even posts prices; in accordance with “if you have to ask, you can’t afford it,” that makes me doubt they’re cheap. The model above — Hytorc’s Stealth — looks like a rare and high-quality piece of work, so odds are they’re worth it for the right user.
