The Worlds Largest Water Wheel, Laxey  |
Laxey Wheel (also known as Lady Isabella) is a large waterwheel built in
the village of Laxey in the Isle of Man. Designed by Robert Casement,
it has a 72-foot-6-inch (22.1 m) diameter, is 6 feet (1.83 m) wide and
revolves at approximately three revolutions per minute. It was built in
1854 to pump water from the mineshafts and named "Lady Isabella" after
the wife of Lieutenant Governor Charles Hope who was the island's
governor at that time. The Laxey Wheel is the largest working waterwheel
in the world. The wheel was used to pump water from the Glen Mooar part
of the ‘Great Laxey Mines’ industrial complex.The Laxey Wheel — World's Largest Working Waterwheel. Photo — Link
The 150th anniversary of the Lady Isabella was celebrated by the people
of Laxey with a grand Fayre on Saturday 24 September 2004. It is
currently maintained by Manx National Heritage as part of the Great
Laxey Wheel & Mines Trail. The Wheel features today on the reverse
side of the £20 notes issued by the Isle of Man Government.

The wheel is water-powered since the Isle of Man does not have a supply of coal but does have an abundance of water.
Water from the surrounding area, including the local river, is collected
in a cistern which is above the level of the top of the wheel. A closed
pipe connects the cistern to the top of the wheel; thus the water flows
up the tower without problem. The water falls from the pipe into the
buckets (formed from wooden slats on the circumference) and makes the
wheel rotate in what is described as the 'reverse' direction. The crank
has a throw of 4 feet (1.22 m) and connects to a counterweight and to a
very long rod. This rod runs along the rod viaduct to the pumping shaft
where the 8 feet (2.44 m) stroke is converted by T-rockers into a
pumping action.
Most of the wheel and rod is made of wood; however, key mechanical parts
are metal to provide tension and bearing surfaces. The rod has attached
wheels at intervals to permit the stroke's motion with minimal
friction.
