Hay Inclined Plane
Encyclopedia
The Hay Inclined Plane is a canal inclined plane
in the Ironbridge Gorge
in Shropshire
, with a height of 207 feet (63 m). It was located on a short stretch of the Shropshire Canal
that linked the industrial area of Blists Hill with the River Severn
. The inclined plane was in operation from 1792 to 1894. It can be visited as part of the Blists Hill Victorian Town
and is also a waypoint on the South Telford Heritage Trail
.
used box-shaped tub boat
s 20 feet long with a load capacity of 5 tons. Twin railway tracks were laid down the incline. The tub boats ascended and descended the inclined plane
on wheeled cradles which ran on the rails. At the bottom of the incline the rails went underwater allowing the cradle to become submerged and the tub boat to either float free or be floated into position. At the top of the incline the rails also started under water then climbed a short slope out of the water to the top of the incline. In operation an empty boat would be loaded into the bottom cradle and a full boat would be loaded into the top cradle. A rope would be attached to the loaded top cradle and it would be drawn out of the water to the top of the incline using a small winding drum driven by a steam engine. The main incline rope would then be attached to the cradle and the loaded boat would descend the incline, counterbalanced by an empty boat ascending on the other rail line. The speed would be controlled by a brake on the main winding drum. On reaching the summit a rope from the small winding drum would be attached to the cradle to control its descent into the upper basin.

The inclined plane is one of the original six simple machines; as the name suggests, it is a flat surface whose endpoints are at different heights. By moving an object up an inclined plane rather than completely vertical, the amount of force required is reduced, at the expense of increasing the...
