The worldwide craze for 'love locks' - New York puts its foot down

Weird, I have never noticed this ... I really like the Moscow Trees but on bridges it seems a bit daft.

It's a bit like lovers carving their names on a tree or writing on a wall. The close up photos show names and hearts on some of the locks so it seems to be a lovers' token and as such each lock will in some way mean something to the owner/s.
It's not new. Lovers have made their marks probably from as far back as cave dwellers.[snip]
When I lived in a cave I carved me and my girls name on a bat.
 
I was completely unaware of this trend until I went to Frankfurt last year and saw a bridge festooned with the things. I like the Moscow trees idea, although that might not work on every bridge.
 
I'd not heard of this at all. Never seen and sign of it in Manchester. Fair enough on crappy metal fences but not on bridges where structural integrity is rather important. Most of those photos just look tawdry in my opinion. I don't care if some couple are smitten - don't be so bloody tacky in public and get a bloody room.

I wonder how much additional loading would be added to a bridge if it was smothered in padlocks on both sets of railings. I'd guess a typical padlock weighs an ounce or two, and one of those pictures looks like there are hundreds of the damn things on a small section of railings.

On bridges where they pose a structural danger, they should have guards on duty and anyone who tries to attach a padlock is thrown off the bridge. :)

Can anyone be arsed to do a backofafagpacket guesstimate of total weights of the locks, just a ballpark figure. My dinner's ready :)

No! That's why I posed the same question too as I'm too lazy to calculate it myself. :D

I am genuinely curious about how much additional loading these shitty locks would put on a bridge though. :)

Ok :D Let's work it out. How much does an average one weigh?

Eta: let's use this one as an example:

I reckon there's 2 or 3000 in that pic.

How much do they weigh? Say 200g (total guess) then 2000 x 200g = 0.4 tons in that pic
Ok, based on a quick search...

Assuming each lock is a 20mm brass one (the second type down on the site below), each lock would weigh 0.53kg. That's not counting the weight of the loved up smugness of course. :D

So if we stick to an average weight of around 0.5kg for simplicity, if there is 2,000 in a roughly five metre stretch of railing that adds up to a fair amount of additional loading for the whole bridge.

Assuming a bridge is 100m long:

0.5kg x 2,000 = 1,000kg
1,000kg x 20 to run the length of the bridge = 20 tons

So assuming the railings on both sides of the bridge are equally festooned with this soppy shit, that would be an additional 40 tons. I'm sure modern bridges have a fair amount of over engineered strength but that might not be the case for historic bridges.

Not bad with the calculations. Pont de l'Archeveche is just under half the length of Pont des Arts - 68 and 155 metres respectively. If des Arts has 93 tons, then l'Archeveche would b e about 40
 
Given the fairly even spread of the load, if doesn't sound like much tbh. I am no bridge engineer though :) other than Lego, that is.
