History
The building of the boat lift was a major engineering achievement. To build the lift 225,000 cubic metres of earth were moved and 55,000 cubic metres of concrete were needed. In order to dig the pits for the two 60m deep float chambers the ground was frozen to a temperature of -40 degrees celsius in order to prevent a possible collapse of the excavation. It took 4 months for the temperature to be lowered by the correct amount. In the neighbourhood of the boat lift a company owned housing estate, the Schiffshebewerk Estate was built.
In the first 50 years of its existence 730,000 lifts were completed. In the years 1980 and 1981 an 18 month long general overhaul was completed. It was at this time that it received its green coat of paint.

Famous quotes containing the word history:
“America is the only nation in history which, miraculously, has gone directly from barbarism to degeneration without the usual interval of civilization.”
—Attributed to Georges Clemenceau (1841–1929)
“Philosophy of science without history of science is empty; history of science without philosophy of science is blind.”
—Imre Lakatos (1922–1974)
“In history an additional result is commonly produced by human actions beyond that which they aim at and obtain—that which they immediately recognize and desire. They gratify their own interest; but something further is thereby accomplished, latent in the actions in question, though not present to their consciousness, and not included in their design.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
