Talk about your impressive feats of engineering! The lift lock raises/lowers you 65 feet in 90 seconds, and does not require any mechanical power other than water pressure. Effectively, the lift lock runs on two great big pistons with a water chamber below. When one lift is at the top they fill it with 1 foot of extra water for weight. Now they open a valve between the two pistons and the water in the top lift pushes over to the other piston lifting the water chamber on the other side. When they get to the top they close the valve, open the lower gates releasing the extra foot of water. They then open the upper gate and add a foot of water and they are ready to go again.
The engineering principal is so very simple – but the scale of the machine to make it work is truly impressive. My guide Rob spent an hour with me in the AM to show me the inner workings and even let me stand under one of the water chambers as it descended – very cool – not a sound!

There may not be a lot in Peterborough, but if you find yourself there, the Lift Lock is well worth the visit!
Cheers!!
Very cool technology... and excellent pics... especially Sue's fright night pose :)
ReplyDeleteKeep 'em comin!
Wonderful explanation Scott.
ReplyDeletethe trip sounds great so far!
