The Great Wheel, Laxey, I.O.M.
Publisher: Frederick Hartmann (1902-1909)
The Great Laxey Wheel (Queeyl Vooar Laksey) or Lady Isabella (as she is also known) is the largest working waterwheel in the world. A brilliant example of Victorian engineering she was built in 1854 to pump water from the Laxey mines.
Manx National Heritage
The Laxey water wheel was designed by the Manx engineer Robert Casement. The wheel’s axle was forged by the Mersey Iron Works of Liverpool but the cast iron rims were made on the Island by Gelling’s Foundry at Douglas. The timbers of the wheel were shaped by Manx artisans and the whole structure was assembled here on the Island. The official opening of this huge wheel took place in September 1854 and it was set in motion by the Honourable Charles Hope, the Lieutenant Governor of the Island. The wheel was named “Lady Isabella” in honour of the Governor’s wife. The wheel has a diameter of 72 feet 6 inches, (over 22 metres), and a width of 6 feet. It is capable of pumping 250 gallons of water per minute from a depth of almost 1,500 feet. The mine shaft from which the water was pumped was sited about 450 yards from the great wheel. The power from the wheel was transmitted to the pumping mechanism by a series of rods supported by and running along an imposing masonry viaduct.
