Boat Lift
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock. It may be vertically moving, like the Anderton boat lift in England, rotational, like the Falkirk Wheel in Scotland, or operate on an inclined plane, like the Ronquières inclined plane in Belgium. History A precursor to the canal boat lift, able to move full-sized canal boats, was the tub boat lift used in mining, able to raise and lower the 2.5 ton tub boats then in use. An experimental system was in use on the Churprinz mining canal in Halsbrücke near Dresden. It lifted boats using a moveable hoist rather than caissons. The lift operated between 1789 and 1868,Charles Hadfield ''World Canals: Inland Navigation Past and Present'', p. 71, and for a period of time after its opening engineer James Green reporting that five had been built between 1796 and 1830. He credited the invention to Dr James Anderson of Edinburgh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strépy-Thieu Boat Lift
The Strépy-Thieu boat lift (french: L'ascenseur funiculaire de Strépy-Thieu) lies on a branch of the Canal du Centre in the municipality of Le Rœulx, Hainaut, Belgium. With a height difference of between the upstream and downstream reaches, it was the tallest boat lift in the world upon its completion, and remained so until the Three Gorges Dam ship lift in China was completed in January 2016. History The boat lift was designed during the Canal du Centre's modernisation program in order to replace a system of two locks and four lifts dating from 1888 to 1919. The canal itself began operations in 1879 and its locks and lifts were able to accommodate vessels of up to 300 tonnes. By the 1960s, this was no longer adequate for the new European standard of 1350 tonnes for barge traffic, and a replacement was sought. Construction of the lift commenced in 1982 and was not completed until 2002 at an estimated cost of €160 million (then 6.4 billion BEF), ...

James Green (engineer)
James Green (1781–1849) was a noted civil engineer and canal engineer, who was particularly active in the South West of England, where he pioneered the building of tub boat canals, and inventive solutions for coping with hilly terrain, which included tub boat lifts and inclined planes. Although dismissed from two schemes within days of each other, as a result of construction problems, his contribution as a civil engineer was great. Early career James Green was born in Birmingham, the son of an engineering family. He learned much from his father, by whom he was employed until the age of 20. He then worked with John Rennie on a number of projects around the country, until 1808, when he moved to Devon, and established a base at Exeter. He submitted plans for the rebuilding of Fenny Bridges, in East Devon, which had collapsed only 18 months after their previous reconstruction. The plans were accepted, and Green became the Bridge Surveyor for the County of Devon. By 1818 he had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longtan Dam
Longtan Dam () is a large roller-compacted concrete (RCC) gravity dam on the Hongshui River in Tian'e County of the Guangxi Zhuang Autonomous Region, China, a tributary of the Xi River and the Pearl River. The dam is high and long; it is the tallest of its type in the world. The dam is intended for hydroelectric power production, flood control and navigation. The dam contains seven surface spillways, two bottom outlets and an underground power station. The Longtan ship lift, part of the dam complex, will be the tallest ship lift system in the world. Construction The dam was planned in the 1950s, but preliminary construction (roads, bridges, river diversion) did not begin until 1940s. Formal construction began on the project July 1, 2001, and the river was diverted by November 2003. A total of of material were excavated from the dam site. Impounding of the reservoir began in 2006, and the dam's first of three operational hydroelectric generating units was testing May 2007. In ...

Three Gorges Dam
The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. The dam generates an average 95±20 TWh of electricity per year, depending on annual amount of precipitation in the river basin. After the extensive monsoon rainfalls of 2020, the dam's annual production nearly reached 112 TWh, breaking the previous world record of ~103 TWh set by Itaipu Dam in 2016. The dam body was completed in 2006. The power plant of the dam project was completed and fully functional as of July 4, 2012, when the last of the main water turbines in the underground plant began production. Each main water turbine has a capacity of 700 MW. Coupling the dam's 32 main turbines with two smaller generators (50 MW each) to power the p ...

Richard Birdsall Rogers
Richard Birdsall Rogers (15 January 1857 – 2 October 1927) was a Canadian civil engineer, civil and mechanical engineer whose most significant achievement was the design of the Peterborough Lift Lock, a boat lift at Peterborough, Ontario, Canada. From 1874 to 1878, he studied at McGill University, McGill College, Montreal, graduating with a degree in civil and mechanical engineering. In 1879, he was appointed a Provincial Land Surveyor and, in 1880, he became Dominion Land Surveyor, a position he retained until 1884 when he entered private practice, taking up the post of Superintending Engineer of the Trent Canal. In this role, Rogers suggested the use of hydraulic lift locks to the Minister of Railways and Canals, John Haggart, who commissioned him to travel to Europe to study existing boat lifts in France (the Fontinettes boat lift), Belgium (Lifts on the old Canal du Centre) and England (the Anderton Boat Lift near Northwich in Cheshire). Rogers was the grandson of a not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peterborough Lift Lock
The Peterborough Lift Lock is a boat lift located on the Trent Canal in the city of Peterborough, Ontario, Canada, and is Lock 21 on the Trent-Severn Waterway. For many years, the lock's dual lifts were the highest hydraulic boat lifts in the world, raising boats . This was a considerable accomplishment in the first years of the 20th century, when conventional locks usually only had a rise. In the 1980s, a visitor centre was built beside the lock. It offers interactive simulations of going over the lift lock in a boat, and historical exhibits detailing the construction of the lift lock. Residents and visitors skate on the canal below the lift lock in the winter. The Peterborough Lift Lock was designated a National Historic Site in 1979, and was named an Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1987. The Trent-Severn has a similar hydraulic lift lock, the Kirkfield Lift Lock, at its summit near Kirkfield, with basins of ...

Anderton Boat Lift
The Anderton Boat Lift is a two caisson lift lock near the village of Anderton, Cheshire, in North West England. It provides a vertical link between two navigable waterways: the River Weaver and the Trent and Mersey Canal. The structure is designated as a scheduled monument, and is included in the National Heritage List for England; it is also known as one of the Seven Wonders of the Waterways. Built in 1875, the boat lift was in use for over 100 years until it was closed in 1983 due to corrosion. Restoration started in 2001 and the boat lift was re-opened in 2002. The lift and associated visitor centre and exhibition are operated by the Canal & River Trust. It is one of only two working boat lifts in the United Kingdom; the other is the Falkirk Wheel in Scotland. Economic background Salt has been extracted from rock salt beds underneath the Cheshire Plain since Roman times. By the end of the 17th century a major salt mining industry had developed around the Cheshire "salt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Western Canal
The Grand Western Canal ran between Taunton in Somerset and Tiverton in Devon in the United Kingdom. The canal had its origins in various plans, going back to 1796, to link the Bristol Channel and the English Channel by a canal, bypassing Lands End. An additional purpose of the canal was the supply of limestone and coal to lime kilns along with the removal of the resulting quicklime, which was used as a fertiliser and for building houses. This intended canal-link was never completed as planned, as the coming of the railways removed the need for its existence. Construction was in two phases. A level section, from Tiverton to Lowdwells on the Devon/Somerset border, opened in 1814, and was capable of carrying broad-beam barges, carrying up to 40 tons. The Somerset section, suitable for tub boats (which were about long and capable of carrying eight tons) opened in 1839. It included an inclined plane and seven boat lifts, the earliest lifts to see commercial service in the UK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorset And Somerset Canal
The Dorset and Somerset Canal was a proposed canal in southwestern England. The main line was intended to link Poole, Dorset with the Kennet and Avon Canal near Bradford on Avon, Wiltshire. A branch was to go from the main line at Frome to the southern reaches of the Somerset coalfield at Nettlebridge. Construction of the branch started in 1786, using boat lifts rather than locks to cope with changes of level, but the company ran out of money and the canal was abandoned in 1803, never to be completed. Proposals Plans for a major canal to link Bristol and Poole, and therefore to make travel from the Bristol Channel to the English Channel easier and safer, were proposed in 1792. The suggested route passed through Wareham, Sturminster Newton, Wincanton and Frome, joining the River Avon at Bath. Collieries in the Mendips near Nettlebridge were to be served by a branch canal, while the main trade was seen as coal travelling southwards and clay travelling northwards. A public me ...

James Fussell IV
James Fussell IV (1748–1832) was an iron magnate operating the Old Iron Works, Mells in Vallis Vale between Mells and Great Elm in Somerset. He was a promoter of the Dorset and Somerset Canal and the inventor of both the roller chain and the balance lock. Invention of the balance lock The balance lock was a type of boat lift designed by James Fussell IV to transport boats up and down a hillside on a canal. An experimental balance lock was built as part of the Dorset and Somerset Canal Invention of roller chain Sketches by Leonardo da Vinci in the 16th century show a chain with a roller bearing. In 1800, James Fussell IV patented a roller chain on development of his balance lock and in 1880 Hans Renold patented a bush roller chain. Business history James Fussell III had leased the site in Mells in 1744, to erect "''a good, firme and substantiall Mill or Mills for Grinding Edge Tools and forging Iron plates''".Fussell, James (2001)''The Fussell ironworks at Wadbury, Mells: An ...
