But how much does your average Manual Swing Bridgw weigh when you push them?

Hi.

In my experience it varies so much that it would be impossible to give a meaningful answer. I have bad memories of the swing bridges along the K&A.

Same as it does when you dont push them.

Mine were on the L&L where on the odd occasion passers-by had to co-opted into the operation

Surely the weight of the swing bridge is immaterial. What matters is the force required to open it, and this only really matters to users if the bridge is manually operated.

This swing structure weighs 2250 tons in normal operation!

Beat me by seconds! It simply depends how well "stuck" the bridge is in its bridge'ole.

as much as a very, very big ball of string

I remember one on the K&A, in the 90s, one morning around Aldermarston. It was frozen in place, what fun I had with that one! The really enjoyable ones are those that enable one to block a car or two, or three, especially if the driver is in a hurry and one really really is trying, honest guv.

 Typically a single digit number of tons, is my guess

The weight isnt that important, if it's well maintained and well balanced it needs hardly any effort to move.

On the other hand if it's not well maintained, as some of the ones we have recently encountered on the L&L, three strong people can only just move it ?

Well a railway turntable is basically a swing bridge and one man and a boy can turn a large Loco
