1877 Le Creusot world's largest steam hammer

[Jon]

The Creusot steam hammer was a 100-ton hammer built in 1877 in Le Creusot, France. Until it was bested by a 125-ton hammer in 1891, the Creusot steam hammer was the most powerful hammer in the world. The hammer was in operation until 1930. In 1969, it was disassembled and rebuilt in the town square. Though no longer attached to a steam source, it still stands today, and is recognized as an International Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers.



The hammer anvil weighs 750 tons, and it was installed on a 1-meter thick oak bed, on solid masonry, built on bedrock below the soil. It was fed by four separate steam furnaces. At the time, it was legendary not only for its record-breaking 100-ton striking capacity, but also for its finesse. The hammer often performed public demonstrations of its accuracy, including corking bottles, breaking eggs in wine glasses, or cracking a nut shell without damaging the nut inside.





A full-scale wooden replica of the Creusot Hammer was displayed at the Paris Universal Exposition in 1878.

Some people believe that the famous hammer was an inspiration for another French landmark that was constructed 10 years later - the Eiffel Tower. Sounds crazy, right? Take a look at the Le Creusot Hammer and the Eiffel Tower side-by-side:

The simple beauty of it is stunning imho. The hollow curvature of the base is beauty, function and strength! And to be built in 1877 impressive to say the least! The foundry must have been inspiring also.

Thanks, ~PJ

That is amazing. The first thing I noticed was the resemblance to the tower and wondered which was made first. The next thing I wondered is what they were hammering with 100tons? Then to be able to control it to break and egg into a wine glass blows my mind. Only the French would have made a steam hammer estheticaly pleasing, not to mention the two curved cranes to either side.
Simply magnificent.

Thanks Frank for the PDF. Having been a member for many years and the SME (Society of Manufacturing Engineers) one forgets after a time how good the resources are in them. I much appreciated the recall and article to support the post!!

Some of the details of the article fascinated me. Particularly the 36' deep footings to bedrock and the 1 meter timbers for the base, but the Anvil at 750T in 6 pieces, at what I would assume would be ~125T each was really inspiring as to how they forged them (in the day in small Bessemer converters) and put them in place with those arch cranes rated at 120T. The picture of the cross section of the shop gives a real magnitude of what it took to support and use this incredible press, let a lone build it at the time, in a short time frame.

I also find it most inspiring to see the history of engineering and architecture that comes from the strengths and beauty of platonic solids and sacred geometry, making it a feast for the eyes and soul as well as practical.

Your"er welcome PJs;
If there is 1 thing that I miss more than anything else is it my rather extensive engineering library.secondly I guess it would have to be the computer I assembled for my office actually 2 computers since I had 1 at home and 1 at work both were twins and would make this little 4 processor 64 bit 16g DDRM 1 tb hard drive laptop look like a 1st generation smart phone.
I find myself all too often thinking I have that or where did I read that, then I spend sometimes hours diving down 1 rabbit hole after the next until I find where someone has published what I was looking for.
Folks like "Imhotep" who may very well be the first structural engineer, Archimedes who everyone knows for his invention of the screw pump and as being one of the great mathematicians of all time

A rabbit-holing I dove. Found the declining moment when creativity was superseded by gleaned material. Now the former achieves little interest, but the latter can't operate in a vacuum.
Entry # 213 in year 2000 George W. Woodruff School of Mechanical Engineering of 1888 in Atlanta, Georgia USA.
The leader transforming mechanical engineering education from a shop-based, vocational program to a professional one built on rigorous academic and analytical methods.
I wonder, has the success to failure ratio of then versus now ever been calculated?

In 2004 a group of soon to be graduating students approached the company I was with in Kuwait for the possibility of completing a project for credit in their degree in mechanical engineering. The project is unimportant the methodology of the completion of said project became very important. the boys , well young men, had the math skills down pat, implementing and understanding what their calculations were all about plus how to judge when pure math skill is not enough to visualize real world circumstances was another matter entirely. All of the math skills in the world can not fully work out every situation or failure instance without cradle to grave knowledge of the materials being incorporated and how different methods of manufacture, assembly or attachment may not always conform to the same exact principals laid out in a text book each and every time in what ever project you are tasked with. For these reasons lab or real world testing will always have to remain the final say in a design. If it weren't then a new space ship model could be built entirely on a computer then constructed in real life and flown to outer space with human passengers and never be required to be subjected to the arduous rigors of pre flight testing

Jon you of all people should know by now never to say (whatever you do don't click on this link) that is a sure fire way to loose members from these forums they will be lost in cyber search for the rest of their lives LOL
great link thanks,I'm off to the link again see ya in a million years
