 The Falkirk Wheel is a rotating boat lift in Scotland. It connects the Forth and Clyde Canal with the Union Canal. The difference in height of the two canals at the wheel is 24 metres (79 ft), roughly equivalent to the height of an eight-storey building.
The wheel has an overall diameter of 35 metres (115 ft) and consists of two opposing arms which extend 15 metres beyond the central axle and take the shape of a Celtic-inspired, double-headed axe. Two sets of these axe-shaped arms are attached about 35 metres (115 ft) apart to a 3.5 metres (11 ft) diameter axle. Two diametrically opposed water-filled caissons, each with a capacity of 300,000 liter (96,000 US gal), are fitted between the ends of the arms.
Despite its enormous mass, it rotates through 180° in five-and-a-half minutes using very little power. It takes just 22.5 kilowatts (30.2 hp) to power the electric motors, which consume just 1.5 kilowatt-hours (5.4 MJ) of energy in four minutes, roughly the same as boiling eight kettles of water.
