4 1/2 inch DRIVE impact sockets?

[atikovi]

Came across a company that sells them in sizes over 12 inches!: http://www.imperial-newton.com/impact+sockets.htm/inch/black-steel/450/6-point/standard/

What equipment or structure could possibly take 12" nuts or bolts? What does a 12" socket weigh or cost? As well as the nut and bolt? What equipment is used with this size socket? I've got a 4' long 1 inch drive flex handle for 2 inch sockets and by extrapolation, you would need a 24 foot long socket wrench for that 12 inch socket. What is the torque spec for a 12" fastener?

I have no idea.....bridges??

Who knows but I would never want to work with it!! I hope I never even have to deal with 3/4"!!!!!

Bridges, pipelines, ocean-going ships, etc, etc.

Heavy industry. Refineries, chemical plants, shipbuilding, bridges and skyscrapers etc. when you get above 1 1/2-2" diameter socket sizes, wrenches and ratchets aren't really used. Hydraulic torquing tools are used. This tooling costs $100,000+ depending on what you need. Check out a company called Bolt-Spec at www.bolt-spec.com They specialize in torquing critical fasteners.

Big structures require big bolts

That picture shows 5 or maybe 6 inch socket nuts. I want to see what takes a 12 incher.

You must have tiny hands if you think that is 5 or 6". That nut is about 12".

My guess would be ship building. There are huge bolts on oil rigs. Some structures prob have bolts that big too.

I measured my hand in that pose and it's about 5 inches across. Bolt can't be more than 6" wide unless that guy is Andre the Giant.

Cargo ships are huge.

The bolt may be only 6 inches, but the nut is probably closer to 9 or 10 inches.

That's some ig stuff. The largest we use is a 4-3/4" socket with 1-1/2" drive, but we use it several times a week. Oilfield stuff gets big, but not as big as ocean vessels!

I just noticed that the crankshaft in that picture is suspended from ropes! They must be pretty strong!!!!!

balanced pretty damn good as well. I'm kind of curious about a price list for some of these sockets.

 

[Super Mech]

Probably used on pressurized reactors in nuclear power plants.

phuckin chinese.
ropes suspended from bamboo sticks

Hold on, let me find a pic of my ex.

 

[metaldad]

biggest drive i found, proto, snap on is 2 1/2 drive, 8'' socket
armstrong, martin, only go up to 1 1/2'' drive
matco - 1''

 

[metaldad]

i see someone else found way bigger.

Maybe the bolts for the 2 bolt mains in this picture:

They don't want to damage the journals.

I noticed it says Baumann on the front of that truck. I am sure there are more than one of them on earth, but I still couldn't help but wonder if that truck has any relation to the Baumann from PB Swiss tools (which used to be called PB Baumann)?

I didn't even notice the name on the truck, I just assumed it was Wartsila since that's what I Googled.

That makes sense, but man oh man I'd have thought they'd have used a bigger rope!

I guess we've finally found the socket that is bigger than it appears on the screen.

My guess...Rope coated steel. IDK.


I wonder what sized fasteners they use on the drive train and props.

 

[rbjscott]

I worked for a large refinery. They had at least two 4 1/2 drive impact wrenches. We used a crane to suspend them, Pipe handles to keep them from turning. They weighed about 400 pounds. 2 and 2 1/2 inch impacts were more common. Later they went to hydraulic tightening for safety reasons.

 

[rbjscott]

They are not ropes. Thousands of Kevlar fibers in a sheathe made for that purpose. Stronger than steel.

[neophyte]

What happens if someone accidentally puts permanent threadlocker on a fastener that size?

 

[Petey156]

I'm curious what would drive these sockets. Think of the weight of the breaker bar

 

[ZRX61]

I want to see the cotter pin for that castellated nut

 

[JKady]

I want to see the cotter pin for that castellated nut

I wanna see the process for getting the cotter pin back out after it's been in a few years...

Sawzall, and breaker with some sort of large hammer tip would be my guess.

 

[redwrench60]

For adjusting these wheel bearings of course!

Aha! Thanks for the info! That makes a lot more sense.

Now I want to see the bearing splitter that pulled it off!

 

[blackedout12v]

those are some pretty cool pictures, is that a freaking turbocharger on that motor

 

[oldtools]

Big nut.

 

[JRC3]

Big nut.

That's nuts!

That cotter pin might have its own cotter pin.
