And you think pittys are expensive to move!

Sp33d.

 

[Kingers]

yeah my bro used to do that sorta stuff, and those things are huge

 

[headsmess]

ummmmm wtf is it? cant quite see

the largest lathe in the southern hemisphere is near me somewhere.... it has a site office on the TOOLPOST

guy got it for a few million at an auction, a few more million to transport it.... and HAD PAID FOR IT with pending jobs already...

 

[Dreadful]

is it a crane ???


Man imagine what they are turning in that lathe

 

[foolsp33d]

i got no idea what it is.. something to do with a power station.. it was half way between moe and sale..

nah not a crane.. it kinda reminded me of a REALLY BIG altenator...

 

[ando]

now thats bloody cool ... i still remember when there was a massive write up in an engineering mag 10-15 years ago when one of the refinaries brought in a massive tank for something or other and took it thru western suburbs somewhere on the same setup taking down powerlines and other obstructions on the way. there were some awesome pics in that mag, i'm sure my dad or grandfather still has it somewhere... just thought i'd share lol at the time it just blew me away the size of the thing let alone the sh!t that transported it... damn what a flashback thanks for sharing speed

YouTube - biggest lathe on you tube? heavy engineering

this isnt really that big...but still... what i love is that the most important part is still just this tiny lil piece of(usually) tungsten carbide

World's Largest Vertical Lathe Column Handed Over

big....

i suck, i cant find any good pics...do i have to track this thing down and take a pic myself? probably... i havent seen it, only told about it by an engineer i know...

but this forum has a decent post about ship propellors...

Hammers? - Page 2 - The Home Shop Machinist & Machinist's Workshop BBS

and thats the main work of these big lathes. ship propellor shafts, and hydraulic rams...

and here i was thinking the rock drills i was making were fairly large...running 50 ton of pressure at something like 16,000nM torque, and twisting a 10 inch shaft like a rubber band when the bit got stuck..

um, heres the rigD100X120 Series II Specialising in Trenchless Equipment & Directional Drilling

had amate email this to me aweek ago while we on BIG machines and sh!t
more came with it but we'll keep it brief

Some facts on the 14 cylinder version:
Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons.)
Length: 89 feet
Height: 44 feet
Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm
Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.
Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder

 

[headsmess]

bloody ship engines you know you have a big engine when you have a hatch in the cylinder for climbing into so as to scrape the carbon off the piston.... 25 thousand litre bloody hell....

now, for the other end of the scale...

the mighty cox 010! a whole 1/4cc of ball tearing power

i got no idea what it is.. something to do with a power station.. it was half way between moe and sale..

Halfway between Sale and moe is a fair distance Fools!! lol.

Must be for a power station or something in the area. I head down that way riding quite a bit.

 

[Kingers]

if thats what ya think it is then its probably getting shipped to the Loy Yang Power station Loy Yang Power Web Site - www.loyyangpower.com.au

its up that way. and the road goes right through the middle of it, its a huge place.

 

[bulldog93]

i see alot of this kind of stuff since we live in a town reliable on mining, we also got a big power station just 40 min away(west, so they have to come through town)

 

[foolsp33d]

Halfway between Sale and moe is a fair distance Fools!! lol.

Must be for a power station or something in the area. I head down that way riding quite a bit.

Lol, but thats where it was! ok actually half way between Moe and Traralgon if you want to narrow it down seeing as you know where im talkin! Next time your heading that way you will notice the single truck pull over lane, has a little concrete section.
But we're gettin specific then! lol..

Wish I knew what it was! Get some pics Bulldog and stick em up! More of that boat engine to if you got em ando!! i have seen similar pics a while ago from the top looking down with workers around the bores...

but yeh.. more pics!!

 

[bulldog93]

won't be seeing some till later this month or next as there was a load a couple of weeks ago...but i should be able to get pics when they come through next.

A cross section of the RTA96C:

The internals of this engine are a bit different than most automotive engines.
The top of the connecting rod is not attached directly to the piston. The top of the connecting rod attaches to a "crosshead" which rides in guide channels. A long piston rod then connects the crosshead to the piston.
I assume this is done so the the sideways forces produced by the connecting rod are absorbed by the crosshead and not by the piston. Those sideways forces are what makes the cylinders in an auto engine get oval-shaped over time.
Installing the "thin-shell" bearings. Crank & rod journals are 38" in diameter and 16" wide:

The crank sitting in the block (also known as a "gondola-style" bedplate). This is a 10 cylinder version. Note the steps by each crank throw that lead down into the crankcase:

A piston & piston rod assembly. The piston is at the top. The large square plate at the bottom is where the whole assembly attaches to the crosshead:

Some pistons:

And some piston rods:

The "spikes" on the piston rods are hollow tubes that go into the holes you can see on the bottom of the pistons (top picture) and inject oil into the inside of the piston which keeps the top of the piston from overheating. Some high-performance auto engines have a similar feature where an oil squirter nozzle squirts oil onto the bottom of the piston.

The cylinder deck (10 cylinder version). Cylinder liners are die-cast ductile cast iron. Look at the size of those head studs!:

The first completed 12 cylinder engine:

 

[headsmess]

and all the tolerancing still held to just as fine a clearance as any other engine...its %(&^ amazing...

wheres some pics of the precision grinders they use? wheres a pic of a valve from one of these?

youd need a crane for installing just them stud bolts alone

which makes me think...wheres a pic of a spanner for one of these?
