11101110 Posted September 22, 2009 Share Posted September 22, 2009 very slowly. If I wasn't headed out on a business trip I'd go and watch a day. http://www.us.areva-np.com/enewsletters/TMI_Journey/content/index.html http://www.areva-np.com/scripts/us/publigen/content/templates/show.asp?P=1311&L=US&SYNC=Y Link to comment
OoPEZoO Posted September 22, 2009 Share Posted September 22, 2009 They are passing within 1 mile of my house.......those things have developed quite the celebrity status over the past few weeks around here. Been a slow summer for news I guess Link to comment
Bill_Walker Posted September 22, 2009 Share Posted September 22, 2009 Wow! This is my favorite photo: Look at the way those carriers have to maneuver to get around that corner! Link to comment
11101110 Posted September 22, 2009 Author Share Posted September 22, 2009 They are passing within 1 mile of my house.......those things have developed quite the celebrity status over the past few weeks around here. Been a slow summer for news I guess Keith, since you are so close, how about some nice close ups of the rigs? I wish I could take some time off and come up and watch the move for a day. But with everything going on at work some related to the massive uprgrades at TMI, I have no time. I will be up there near the end of the outage though. PICTURES Link to comment
OoPEZoO Posted September 23, 2009 Share Posted September 23, 2009 I suppose I could check out the travel schedule and see if I can snap some pics. EDIT: Looks like it will be coming through town Thursday-Friday. If the timing works, I might be able to get some shots while its rolling through the middle of Columbia Link to comment
motoguy128 Posted September 23, 2009 Share Posted September 23, 2009 That's a pretty nifty trailer for making thoee tight turns on the mountain roads. Seems like the title of the photo should be "Why NOT to build a large power plant where the only access roads are in windy hilly terrain." I used to live near that area and rode my bicycle on the roads they are probably using and past TMI. We had a large specially designed vessel installed a few years ago where I work. It was too large to ship over the road. It came via the atlantic ocean, then loaded on to barges and up the Mississippi River. But it only weighed about 150 Tons. They manufacturer the blades for the large Siemens wind turbines near where I live. Now those are pretty impressive. Not very heavy, but quite large. They ship most of them by rail on special rail cars. Link to comment
motoguy128 Posted September 23, 2009 Share Posted September 23, 2009 Then again, the expressways I remember in PA weren't much wider than 2 lanes roads and almost as twisty in some parts. So I suppose it's a wash. Link to comment
enfoman Posted September 24, 2009 Share Posted September 24, 2009 Notice the wheels on the trailer- they can actually turn in order to make a tighter radius. Bob Link to comment

Joe Frickin' Friday Posted September 25, 2009 Share Posted September 25, 2009 Amazing ... Apparently these transport rigs can "turn on a dime" ... I've seen descriptions of these things before. Many many wheels for load distribution, and each one is independently steerable via computer-controlled electric motor. To maneuver through a turn, the computer orients each wheel so that all of them are tracking through a turning radius with a common center. Presto: no skidding/dragging of tires. You can see this clearly in your pic1 link. Contrast that with the 42-wheel big-rigs we have here in Michigan. Yes, eight 4-wheel axles under the trailer, all the way up to just behind the tractor. Take a sharp turn, and most of the wheels on the trailer are being dragged sideways until the turn is completed. It ain't pretty. Link to comment
motoguy128 Posted September 25, 2009 Share Posted September 25, 2009 What's in those chemical totes on the ends of each "crawler"? Is that extra hydralic fluid for the crawlers? I hope it doesn't leak that badly. Althouhg it is a long trip. Maybe it's at least biodegradable of food grade hydraulic oil. I thought most of those crawlers were 100% hydralic operated including the rotation and forward motion. I've seen on "Mega Builders" or soemthing similar the same devices used ot move other large/heavy objects including buildings. Link to comment

Take a sharp turn, and most of the wheels on the trailer are being dragged sideways until the turn is completed. It ain't pretty. Certain dual-rear-axle trucks I see around here *almost* do that. Each axle's tires flex mightily in opposite directions in a sharp turn. Heck, they probably do drag like MI trucks when I'm not looking ------------------ Chris (aka Tender Vittles ) Little '77 KZ400 in the Big Apple Black '99 RT for Everywhere Else, such as ...

OoPEZoO Posted September 26, 2009 Share Posted September 26, 2009 For another useless tidbit of information. The original TMI heat exchangers were designed to be transported via railway. They were brought up on the Norfolk Southern railway that parallels the Susquehanna River right to the front door at TMI. The new heat exchangers would have followed the same path......EXCEPT, due to new standards implemented since TMI was built, they were not allowed. Apparently the mounting flanges on the original exchangers were not installed at the factory. Instead, they were installed and welded once they reached their final destination of TMI. The new standards required the flanges to be installed and welded before transportation, which made the exchanger too large to go through the railway tunnels. SO, we are stuck with this slow and VERY expensive alternative. Link to comment
ESokoloff Posted September 26, 2009 Share Posted September 26, 2009 But obviously the NRC(?) mandated this for safety so in the long run it's a small price to pay. Link to comment

That would make sense. It would allow you to locate the fuel tanks where it's convenient for maximum felxibility or different load configuartions and dimensions.... while keeing the platform as small as possible.
