Title: Man hole Cover Collection
Post by: Rangnath on May 03, 2011, 11:20:05 PM
Each cover weighs between 15 and 55 Kg. My Album is quite heavy as you can imagine, containing as it does with over 55 specimens.  My focus is on Indian Man hole covers and while many of mine come from Portland, Oregon, my pride and joy is this one from Brooklyn, New York City, which is over 105 cm in diameter. 

Look for these on Ebay when I intend to part with doubles.

You should visit Rome. I noticed that there were quite a few with fascist era symbols left.

How do you cover the holes when you have put the covers in your vest pocket? If you wish, I could send you some duplicates of my collection of hub caps. They would prevent people from falling in and double as speed bump.

And then you have the problem that some of the pieces which appear to be genuine are mere imitations. ;D (Click the manhole cover image on this page http://www.haase-und-knels.de/arbeiten/kommunikation-im-raum.html to see it "in action".)

Man hole cover? Cover manhole?  Hmm. 
Thank you all. As usual, I learn much more than I wanted.
 I intend to visit Rome next April, in fact. As for trading hub caps for manholes, I'm not sure figleaf.
Aren't we dealing with apples and oranges, or should I say, bananas and donuts?

Dear Richie,

The Manhole cover you show from India, is it made of Cast Iron or Concrete? In India, the earlier Manhole covers were made of Cast Iron, but due to thefts of these covers, now they are mostly made of Concrete.

Abhay
Title: Re: Man hole Cover Collection
Post by: Rangnath on May 04, 2011, 05:54:30 AM
All of our manhole covers are made of cast iron.  Someday, probably sooner than I would like, thefts will lead to replacements with concrete.  But as of now, we have some wonderful examples of Indian iron work in the streets of Portland and, as I've recently discovered, in New York City as well.

Very unusual interest of collecting 'manhole covers"


Square manhole cover in Hong Kong covering the sewers

As you walk along the Park Promenade from the ferry terminal and Hong Kong Disneyland Hotel you encounter dozens of manhole covers, most of which have a small Mickey in the middle.

Historic Shanghai right under your feet
A Shanghai attraction under your feet rather than a 100-plus stories in the air



(http://i.cdn.cnngo.com/sites/default/files/imagecache/article_large/article-images/large/Historic_Shanghai_.JPG)

The Shanghai Municipal Council (SMC, 工部局, literally "Works Department”) was wholly foreign-controlled run by the Brtis, Americans, New Zealanders, Australians, Danes and Japanese. Neither the Chinese nor the French had a seat on the council.

Buildings mysteriously come and go in this city -- it’s just how it is -- but the little bits of historic Shanghai that manage to stick around which are extraordinary to stumble upon. We’ll admit that a manhole cover is rarely something to get excited about, but when it’s square and reads S.M.C. it’s a rare find.

S.M.C, the Shanghai Municipal Council, is the group that ran the International Concession from 1854 to 1943. The SMC (along with its foreign residents) maintained its own police force and trained its own military reserves. What the SMC really is known for though is the architecture and development of The Bund, which is where we stumbled over this manhole cover.

Located on Fuzhou Lu between Henan Zhong Lu and Jingxi Zhong Lu (near Hamilton House), this square manhole cover has withstood much of the area’s renovations even if it’s easy to miss in the pavement outside a public security bureau building. Although we don’t suggest stopping to snap a photo (the station's guards aren’t huge fans cameras on that block), definitely wander past to see a little piece of historic Shanghai that doesn’t look like it’s going to be swept away by the bulldozers of change any time soon. It's not 1930s Shanghai glamour but it's still an interesting window into local history.

This is far from the only historic manhole cover to survive urban development so keep your eyes pealed across the Bund area as well as in the French Concession where many of the old covers are actually still in use today.

James Joyce? Right. This is a plaque on platform 1 which commemorates the one night Joyce and his wife spent in the city ... because they "mistakenly disembarked there, believing they had reached their destination - the city of Trieste." ;D http://slonews.sta.si/index.php?id=1049&s=44

Repeating an imagined story on how the couple spent the night in Ljubljana here, from the page you linked to. It makes this story even better.

Peter


"Slovenian author and screenwriter Miha Mazzini gave probably one of the most amusing accounts of Joyce's "incomprehensible" novels: when he and Nora got off the train in Ljubljana, Joyce is severely beaten up by a group of tense citizens due to a breakdown in communication. Swollen from the beating, Joyce mumbles something unintelligible into his beard and nobody can understand him. He then concludes: "When I began talking unintelligibly, no doubt obscurely to a listener, everyone was nice to us." Unintelligibility is immortality!

Some passers-by find the meaning of the plaque by sculptor Jakov Brdar at Ljubljana's central railway station equally obscure. Well, couldn't we say this is a good start?"

Start looking and you find the most amazing things. Here are Dutch manhole covers from the Southern town of Maastricht and the Northern town of Leeuwarden. The lovers in the park go well in a Burgundian place that loves fun, while the mystical conch with its semi-religious connection fits austere Leeuwarden.

I too never imagined such things.  Man hole covers...non utilitarian...artistic....who would have thought it.  I have never seen one in person that wasn't utilitarian.  I was interested in them because they are mostly cast and metal casting is a subject that interest me.
Collecting them?  I never imagined.

By comparison, collecting anvils doesn't seem so strange   ;D

Here in the UK there has been a lot of man hole & drain covers stolen for their scrap value, driving around in Worcestershire a few months ago there were traffic cones to mark where the covers were taken & I can't imagine how dangerous it would be driving at night  & not spotting the hole. The police have issued warnings to scrap merchants who take in these stolen covers that will face severe penalties. According to Wiki it's a worldwide problem & even concrete replacements are stolen to get the reinforcing metal inside  :o

Side note: There is another connection between that seal and "water" in Freiburg. In the 1890s the city built a container for drinking water called Wasserschlössle (https://upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Wasserschlösschen_%28Freiburg%29_8971.jpg/578px-Wasserschlösschen_%28Freiburg%29_8971.jpg) - actually a little château d'eau. :) The design was inspired by the city seal ...

This week we visited the tiny city (city rights since 1482) of Bronkhorst (https://en.wikipedia.org/wiki/Bronkhorst) on the river IJssel (https://en.wikipedia.org/wiki/IJssel), Netherlands. 150 inhabitants, a razed-down castle full of robber knight legends, an excellent indigenous beer, one good hotel and restaurant, and quiet in November (you shouldn't come in summer, though the cobbles ward off scooters and there are mainly pensionados pottering about).

This is the city man hole, there are probably only five or six of them. Useful: it is also the ground plan, making it even more difficult to lose your way in the streets of Bronkhorst.

Found this manhole cover in the old main street of Groningen in the north of the Netherlands, an old city soon to celebrate its first millennium of minting coins. Its beloved symbol is the Martini Tower, the 290 feet bell tower of the St. Martin's Church, founded about 800 AD and now a proud Gothic building of the 15th century. (Feeling a bit chauvinistic about the place where once my cradle wobbled).

It is quite interesting to note that many of the Man-hole covers shown in this thread have been manufactured in India.

One of the reasons for this is being that these Covers are made of S.G.C.I. (Spheroidal Graphite Cast Iron), also popularly called Ductile Iron. In India, we have many foundries producing this S.G.C.I. castings.

One of the main properties of SGCI is that it is very malleable and does not break easily with impact load. This is very necessary as Man-hole covers are subjected to lot of Impact loads due to moving traffic over them.

This one is a little different - one of those "squirrel gets stuck in manhole cover" stories. ;) Happened in Dortmund (NW, DE) today ... and the fire dept. could not get our furry friend out. (Story (https://www.waz.de/staedte/dortmund/eichhoernchen-steckte-in-gullydeckel-feuerwehr-befreit-es-id226237515.html) in German.) So they actually informed the police, took the manhole cover with the squirrel to a vet while police officers blocked the open manhole for about an hour.

Here is one (a manhole cover, not a squirrel) from Wuppertal, NW, DE. The coat of arms is a combination of the two biggest "portions" of the city: Barmen had the Lion of Berg (https://en.wikipedia.org/wiki/Duchy_of_Berg) (which can be found in the CoA of several cities around here) standing on yarn, referring to the textile industry history of Barmen. Elberfeld's CoA also featured the Berg lion, holding a gridiron, a reference to St. Lawrence, patron of Elberfeld. And when Wuppertal was founded and then got its name in 1929/1930, the two coats of arms were combined ...

A short stay at Verona learned that this venerable ancient Italian city is a real treasure trove of manhole cover varieties. Here are a few.
I didn't have time to look at the ground all the time, though. It was the start of the opera season and giant Aida requisites were scattered throughout.

The manhole in the first image is marked "Made in Italy" if it really was, then why not use Italian? ???

The "made in ..." label is a British invention that was supposed to hinder imports. It is in principle not meant for the home country, but for exports, so it makes sense for an Italian product to be labelled in a trading language.

The "made in ..." label turned out be be a nice quality indicator if the image of the exporter is relatively good. Making manhole covers (basically a cast iron product) is a cheap labour industry, unsuitable for a developed country like Italy, so they are evidently trying to compete on quality, not price.
