Ship cover
A ship coating or Schiffszug is to transport a device to vessels over a dam of a body of water to the other. This means that height differences can be overcome. The ship cover can also be seen as the forerunner of the lock or a ship lift .
Construction and function
Historically, the ship's cover consisted of inclined planes that were covered with greased wooden planks. Sometimes the ships were also rolled over tree trunks. At the highest point there was a simple winch with which the ships were hoisted. In ancient times there was a ship covering the Isthmus of Corinth between the Gulf of Corinth and the Aegean Sea . There the ships were pulled over land on carts. The American engineer James Buchanan Eads and the Mexican government planned from 1880 to have a ship train built over the isthmus of Tehuantepec by the jointly founded Tehuantepec Interoceanic Ship Railway , which would transport ships from the Atlantic to the Pacific and vice versa by means of very large railroad cars. After Eads' sudden death in 1887, the plan was abandoned.
Modern systems
In the Netherlands, two electrical systems for recreational boating were built in 1992 and 2002 on the Regge near Rijssen-Holten and Hellendoorn . These systems are powered by battery power from the boats. The vehicles drive on a wagon and thus overcome a height difference of 1.20 or 2.50 meters.
In Broekerhaven, near Enkhuizen , there is an electric ship lift built between 1923 and 1924, which connects the town's port on the Markermeer with the canal system. The boats go into an open tub, are pulled up, then moved laterally to the canal and let down again.
