That's a big thumper! | ||
| Boogiman1981 |
Wow. Link or back story? | ||
| Strokizator |
Yeah, I'm trying to figure out what kind of contraption has a connecting rod with two big ends. The square thing on the floor looks like it slides up & down on something but just what the heck does it do? | ||
| Froggy |
No backstory yet, I found it on another site, it appears to be off a large cargo ship. | ||
| Hughlysses |
It's a crosshead. Big engines have a cross head just like steam engines used to. The piston rod connects from the piston to the crosshead; the rod seen above connects from the crosshead to the crankshaft. The engine in this pic is upside down, but you'll get the idea:  | ||

That's going to cost a few bucks to fix. | ||

I haven't seen anything that made me do a double-take in quite a while. Looks like something stopped, and something kept moving  | ||
| Natexlh1000 |
I bet it "finally stopped making that clunking noise". Perhaps water locked up the one jug that failed while the others worked together to mess up the rod? | ||

Wow! In 70 years have seen a big engine or two but WOW! | ||
| Darth_villar |
The really crazy thing, is that it looks to be made from a single block of billet! | ||
| Treefrog |
I wonder how that thing sounded while it was knocking. | ||
| 6gears |
If this is the same engine....I used to have a picture that had 4 guys standing on top of the piston looking at the cylinder walls! LOL. Let me see if I can find it. | ||

Here is a link, but still can't find the picture I am thinking about though. It is a 2 stroke that makes 109,000 HP. http://www.autoblog.com/photos/w-rtsil-sulzer-rta9 6-c/#photo-4314483/ | ||

Kawasaki makes a big 2-stroke like that....  Edit: Do you see at least 3 people in the picture?? (Message edited by pwnzor on December 07, 2012) | ||

I'm assuming the rod is the least of all the damage. With a bend like that, the cylinder and block have to be destroyed too? | ||

http://en.wikipedia.org/wiki/W%C3%A4rtsil%C3%A4-Su lzer_RTA96-C 5,608,310 lbf·ft @ 102 rpm  | ||
| Hughlysses |
We all think of 102 RPM as being VERY slow, but even at that speed the crank is making 1.7 revolutions per second. So in one second, that monster rod/crosshead/piston assembly in the photo above would have gone full stroke top to bottom, full stroke bottom to top, full stroke top to bottom, and ~1/2 way back down on another stroke. Can you fathom the jolt/noise that thing made when whatever failed? | ||

Can you fathom the jolt/noise that thing made when whatever failed? It's the same noise a stack of money makes when you light it on fire. | ||
| Hybridmomentspass |
pwn - i see the three and im glad you point that out, good reference on how HUGE that thing is  | ||
| Strokizator |
At full load, a 14 cylinder engine will use over 4300 gallons an hour! Does anybody have the federal-mogul part number for the rod bearings? | ||
| Sifo |
Needs a turbo! | ||
| Mr_grumpy |
Maybe ran aground, prop stops suddenly, motor tries to keep going. | ||
| Kyrocket |
Yeah, ya reckon that's a part they stock? I've been clicking links and reading about the Emma Maersk, wow, what a piece of machinery. | ||
| Mr_grumpy |
My mind boggles at the sheer size. Imagine working on the thing, goodness knows what the accompanying toolbox looks like! | ||
| Bgbrd |
Those bearing cap bolts must be torqued in "YARD TONS". I wonder what rpm an engine like that turns at working speed? | ||
| Hybridmomentspass |
bgbrd link says something like 120 rpm max | ||
| Sifo |
The wikipedia link claims 22 to 102 RPM. http://en.wikipedia.org/wiki/W%C3%A4rtsil%C3%A4-Su lzer_RTA96-C#Technical_data_.28as_of_2008.29 I think the picture way at the top is what happens when you hit 120 RPM! | ||
| Mr_grumpy |
"Nah mate, that's not under warranty, operator abuse, you must have over-revved it. I can put a claim in to head office for you but I know what they'll say. Those rods are on back order too & you'll have to pay up front, of course we'll reimburse you if the claim does go through." | ||
| Natexlh1000 |
Found: http://www.marinediesels.info/Horror%20Stories/tes tbed_smash.htm No more info but more pics. Gotta love an engine that has a built-in ladder inside the crankcase! | ||
| Natexlh1000 |
Looks like that site has some obnoxious scrips running that forwards you to the main page. The article I was attempting to sent you children is under the "horror stories" heading and "test bed smash" | ||
| Sifo |
Nate's link seems to have a couple more pics under "test bed explosion" too. Lot's of smoke and fire! |
