THIS is a towing rig

[dordtrecht5]

This is Elvis. This truck is owned by Barnhardt Heavy Haul and has a v-12 Detroit two-stroke. The tires are 5' tall and the leaf springs are 2 inches thick. The leaf pack is seven on each axle. The trailer in the picture has 18 steerable axles, and are dual on each side totaling 144 tires on the trailer. This particular haul is a "Herzig" filter on the jobsite I am currently working on in South Dakota and weighs approximately 145 tons. It takes three cranes to maneuver the filter from it's prone to vertical position.

Here is another picture of it being hoisted into place. The main crane is a 2250 Manitowac Maxer. The tailing crane is another 2250 without the maxer attachment. The third crane, which takes the hoisting apparatus off of the filter once it is vertical is a Manitowac 777.

cool pic's, Big stuff.

cool pic's, Big stuff.

yes, it is. just to give a small perspective on the crane, the main boom you see in the second post and picture you can drive one of our duramaxes through.
The boom height is about 7', and the width is about 8'. It is rented from Dawes Crane Rental, a subsidiary of ALL Erection and Crane Rental out of Milwaukee. They are a top-notch outfit. Two operators/mechanics, myself, and three other Union Ironworkers erected the 2250 Maxer. It took 6 days and came in on about 25 trailers.

It is my understanding that the Detroit in the truck is 1,000hp. I have personally watched this truck pull the trailer with 145 tons on it at idle speed. Top speed on it is about 50 mph. It has an air activated starter on it. It is equally impressive, and yes, it is loud.

what's the filter for?

 

[dordtrecht5]

It is a particulate filter for the gas turbine of this powerhouse. There are a total of 14, I think, that go into the Herzig. I am not a boilermaker, I am an Ironworker by trade. So I am in no way an expert of this part of the process. I did, however, help build the stair tower next to it ... :woott:

 

[dordtrecht5]

I made a mistake BTW ... it is a V-16 Detroit.

 

[ocwelder]

Biggest engine I ever worked on was a Detroit series 20E7 V20 in a tug boat, 4 superchargers, 4 turbos each about 14" in Dia.

 

[dordtrecht5]

Wow...that is very impressive. I think this engine in Elvis is the same V-16 that is in the Big Bud tractor.

 

[ocwelder]

That would make sence. That is a big a$$ tractor.

Planetaries work wonders :thumb:

My aunt's heavy haul trucks can get a 450k+ load going with the c16 in the truck idling

Pretty cool, i love watching this stuff on job sites. Its pretty cool to watch them take tower cranes down, they can take themselves down until they get to a certain point, then they bring in 2 more cranes, one to take the tower crane down, and one to take the crane down that took the tower crane down. lol

You travel around to the power plant jobs a lot? Luckily with the economy being how it is powerplants are still building, keeps a lot of iron workers and boilermakers from setting at home right now.

 

[dordtrecht5]

Yes, I do travel a lot. Lost count, but I think I have worked in 13 states over the past 5 years. It's hell come tax time! Work isn't like it used to be at all ... At least the industrial side of things are still somewhat there, like you said. Largest hoist to date for me is 275 tons down in Holcim concrete, south if St. Louis.

Another pic of Elvis taken 4/16/11. Ya that is snow...we got 3 inches on Friday night.

I'm no expert either, but I believe Herzig is the phoenetic way to say HRSG, as in Heat Recovery Steam Generator. The filters clean up the air before it is burned with gas in the turbine, and waste heat is used to generate steam that can be used to drive other turbines.

Cool rig.

 

[dordtrecht5]

There you go ... that acronym is exactly correct. Thanks for clearing that up. I appreciate it.

Here is two more pictures that I took today. This is towing 250 ton generator and the rear axle leaf spring. You can see that my hands are spread apart a little bit. Kinda big for a leaf spring. This particular tow was kinda a waste at one point because they had to get a Cat D6 to start the tow. There simply isn't enough counter-weight on Elvis to keep the tires from spinning.

 

[dordtrecht5]

I think in the original post I said that there were 7 leafs, but there are nine.

Here is the quote from Wikipedia about the Heat Recovery Steam Generator:

A common application for an HRSG is in a combined-cycle power station, where hot exhaust from a gas turbine is fed to an HRSG to generate steam which in turn drives a steam turbine. This combination produces electricity more efficiently than either the gas turbine or steam turbine alone. Another application for an HRSG is in diesel engine combined cycle power plants, where hot exhaust from a diesel engine, as primary source of energy, is fed to an HRSG to generate steam which in turn drives a steam turbine. The HRSG is also an important component in cogeneration plants. Cogeneration plants typically have a higher overall efficiency in comparison to a combined cycle plant. This is due to the loss of energy associated with the steam turbine.

Yeah, kind of a mute point when you can't put the 50 tons of ballast on the prime mover so that it can get enough traction to do its job.

We have an old Mack with a Cummins in it that has ate 2 sets of rear axles pulling an 800 tonne piece plus the trailers (total was probably about 1,100 tonnes). It has over 30 tonnes of ballast on the truck. At one point they had 4 trucks plus self propelled trailers and 2 rubber tired wheel dozers to pull the last hill.
