Falkirk Wheel, Scotland, United Kingdom

The wheel was constructed by Butterley Engineering at Ripley in Derbyshire under Millennium Plans to reconnect the Forth and Clyde Canal with the Union Canal, mainly for recreational use.
Operation
The wheel rotates together with the axle, which is supported by four-metre-diameter slewing bearings that are fitted to the ends of the axle and have their outer rings mounted on the plinths, which in turn are constructed on top of piled foundations.
