8/13/2006: The Falkirk Wheel
Thanks to Happy Monkey for pointing to this Flickr set and picking out three of the best shots of this. A while back we had Germany's amazing water bridge, but I think, with this item, the Scots have topped it. Presenting the Falkirk Wheel. It's in Falkirk! In this case, they had two canals coming at each other, one 24 meters higher than the other. Rather than bridge them, they wanted to connect them and allow boats to move from one to the other. But how to get the boats up 24 meters? The Wheel answers that question by simultaneously lifting 300 tonnes of boat and water while simultaneously lowering 300 tonnes of boat and water on the other side, as it turns. The top boat is spun around to the bottom position and vice versa. Wow. It's said that good engineering, working with nature instead of against it, comes up with naturally beautiful designs. We've seen that in the awesome Millau Viaduct and now here in this Wheel. The lemon wedge on the bottom is an observatory... I want to observe it. Good work by those Scottish engineers! (Doohan (RIP) applauds. Yes, yes he's not an actual Scottish engineer, but he did play one on TV.) |

Damn, I saw a couple news articles and several websites describing this gizmo, when it opened, and not one of them had pictures any way near this good. Everyone was getting too close, showing details instead of pictures like these that show clearly how it works.
Good work HM, UT. The way it is balanced, is so simple, it blew me away. Brilliant!

It is very cool. I like it a lot.
I have to wonder though, if a series of standard canal locks would be cheaper to build and easier to maintain. |

If it's not Scottish, it's crap!

Damn - watched a programme on this months ago and thought at the time that pictures of it would make a good IoTD. Never got round to looking it up though
It was one of the UK Millenium Projects (another one was the infamous "wobbly bridge" across the Thames). The Falkirk Wheel connects Glasgow and Edinburgh by canal, and although there was some discussion as to whether this was strictly necessary, the wheel has now become a tourist attraction in its own right. You can park your car and take a boat trip for the specific purpose of riding the wheel.

This is really great. I enjoy seeing proof that there are some very intelligent people on this planet. All hail the Scots... they did very well on their whisky venture also, IMO.
Best part about this to me is how they worked in harmony with nature instead of destroying it as usual.

This is a much more elegant solution instead of building a huge set of locks like these on the Erie Canal.

Looks like a ferris wheel for boats.

even more cool, the play park next to it is sponsored by irn rbu, scotland's other national drink

This new boat wheel is elegant looking and is fascinating. The rotation of it seemed simple enough with the two tubs acting as counterweights, but I couldn't imagine how the gates worked. Usually a lock has the gates open against the uphill side of the water so water pressure will hold them shut when they close. These gates have space constraints. There is basically zero clearance between each gate of the tub as they are closed against the mating gates of the canals. There is no place for them to open. The only solution I could imagine is that the gates somehow lie flat on the bottom of the tub, and then rotate up into position. Then I couldn't imagine how they could seal, since there would be little water pressure against them. So I looked it up. Turns out I was right that the gates are very complicated. Quote:
Another article I found says that the system is computer controlled and requires input from over 600 sensors to run properly. This is sounding less and less elegant all the time. Quote:
I predict that this boat lift will be extremely expensive to maintain, and that it will cease to operate within 20 years or become a huge money pit as engineers try to keep it working. However, it will probably still be measured as a success, because it's true purpose it to be a tourist attraction, and it succeeds at that. It's a unique engineering marvel. |
