Big Crane

[Jack B]

I grew up in Manitowoc Wis. and we made the big red Manitowoc cranes you see everywhere. A few years ago the company moves to Pennsylvania along with our proud name.
Other companies moved into the many buildings left empty.
One made the huge tubes for the wind generators and and somehow they got a contract to build a new crane I don’t know much about it we’ve all been watching it being built along the river and they finished it a few weeks ago and tomorrow it’ll be on its way to the Navy from what I heard to be used to lift submarines.

always good to see old big buildings and shipyards, etc. being used again vs. just sitting rotting or being torn down into condos or apts., etc.  all the while 100's of jobs are being sent to Mexico or India or Canada, anywhere but the US.   My wife and I have worked for way, way too many companies sending jobs overseas seeing 100's of employees jobs gone for good.   

We enjoyed when kids growing up years ago the SS Badger I believe coming into port up there AT NIGHT in Manitowoc being able to get pretty up close to it feeling like it was going to run you over it seemed that close, especially at night, with all the lights on.  The Captain that night must have gotten a tad bit too close to the wooden beams protecting the shoreline and made a HUGE BANG crashing into the boards shook the ground a tad where we were standing on land nearby.

Uh - what is that crane rated for ? A modern US Nuc Attack submarine displaces 7000-10,000 tons ( 1 ton = 2000 pounds, so you're talking 14,000,000 pounds - 20,000,000 pounds) - and that's assuming you can get it balanced so it doesn't slide in the cradle. The Ohio SSBN are bigger than that.

The biggest cranes I've heard of are the ones that Newport News Naval shipyard uses to piece CVN's together. Those modules are HUGE.

I don’t know much about this crane but I heard it takes 2 cranes to left a sub.
Does that sound right?

The "displacement" numbers on ships aren't what the vessel weighs, it is the amount of water it displaces. So if it displaces 10,000 tons, the volume of the vessel that is below the waterline is large enough to move 10,000 tons of water. I'm not sure if subs are figured for the total boat or just what it displaces while on the surface.

The ship in my signature below is the SS Badger.  The largest STEAMSHIP on the continent - maybe the last.  It'a a coal-fired compound steam engine - the height of piston steam tech.  There was once a fleet of them crossing lake Michigan - actually US Highway 10.  It has railroad tracks on the main deck - they hauled trains across.  Now it's cars, RV's and really big trucks.  I had to wait for them to unload a way oversize truck hauling a turbine tower.  It's really interesting and historical - take it across the lake sometime.  Over 400 ft long, reminds me of the passenger liners we took across the Atlantic in the 60's. Salons, cafe's, movie theater, computer game arcade, gift shop, saloon, Bingo, entertainment, museum, cabins.  Not just a ferry.  And you get to park your bike - the "parkers" don't handle bikes.  

Here's a larger copy of my sig pic.

Did a tour of the UP 3 years ago and came through Manitowoc on the way home to Indiana. Stayed overnight and went to the maritime museum there and also toured a submarine. Fantastic museum and the tour was great. Next day we took the Badger across the lake to Ludington. Fantastic trip. The Badger trip was a highlight.

We did the museum and submarine tour as well.  The sub I remember was a VERY tight fit between doorways for me having to turn my body sideways to fit thru and even that rubbed a little.  I cannot fathom being on a sub like that for even tad under 6 ft tall you can hit your head on items and was very very tight fitting quarters for me.  I guess there has to be a weight limit right if in the military?  Or in case of a sub, also a height limit? 

Mark, that is a good pic of the SS Badger.  We at night were standing next to the fencing by the wooden posts it docks up against and the boat hit the wooden piers pretty hard crashing into them shaking the ground next to us.  Is a sight to see a HUGE ship coming right at us with bright lights mere feet away in the complete darkness only seeing the lights of the ship lit up with a boarder of a boat in the dark.  My kids were younger at the time and were worried the ship would hit us and to be honest, I got a tad bit leery as well for a split second.

I'm not sure if subs are figured for the total boat or just what it displaces while on the surface.

According to what I learned in physics, the weight of water displaced exactly equals the floating vessel's weight.  Therefore, when a sub is either on the surface, or in equilibrium under water, its displacement (in tons) is its weight.

I'm pretty sure you're correct, I only had one class in physics but, I stayed at an Econo Lodge just the other night.

Here’s some information I found.

The crane was left Manitowoc.
If you look to the right you will see our WWII submarine.

Hmm...wonder who the poor slob is that has to rotate the tires on the carrier vehicle?
