An inclined plane is a type of cable railway used on some canals for raising boats between different water levels. Boats may be conveyed afloat, in caissons, or may be carried in cradles or slings.

History

Inclined planes have evolved over the centuries. Some of the first were used by the Egyptians to bypass waterfalls on the Nile. These consisted of wooden slides covered with silt which reduced friction.{{cite book |title=Foxton Locks and Inclined Plane A Detailed History|year=1988 |publisher=Department of Planning and Transportation, Leicestershire County Council | isbn=0-85022-191-9|pages=3}}
