De Hef
De Hef (), officially Koningshaven Bridge, is a vertical-lift bridge over the Koningshaven (Kings Harbor) channel (geography), channel at the port of Rotterdam, Netherlands. Built in 1927, the bridge was part of the Breda–Rotterdam railway line until it was decommissioned in 1993. Today, it is a Rijksmonument heritage site. History The predecessor bridge dated from 1878. Its configuration as a swing bridge proved an obstacle to shipping (the most notable incident occurring in 1918, when the bridge was struck by the German vessel ''Kandelfels''), and it was replaced by a lift bridge in 1927. It was the first bridge of this kind in western Europe. The bridge was the subject of a 1928 film by Joris Ivens, titled ''De brug''. Redevelopment Plans to demolish the railway line and bridge in 1993 were abandoned after widespread protests from local residents. The line was removed but the bridge was left in place as a Rijksmonument national heritage monument. In November 2014, th ...

Vertical-lift Bridge
A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck. The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridges. Generally speaking, they cost less to build for longer moveable spans. The counterweights in a vertical lift are only required to be equal to the weight of the deck, whereas bascule bridge counterweights must weigh several times as much as the span being lifted. As a result, heavier materials can be used in the deck, and so this type of bridge is especially suited for heavy railroad use. The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it, due to the deck remaining suspended above the passageway. Most vertical-lift bridges use towers, each equipped with counterweights. An example of this kind was built in Portland, Oregon, U ...

Channel (geography)
In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While ''channel'' typically refers to a natural formation, the cognate term ''canal'' denotes a similar artificial structure. Channels are important for the functionality of ports and other bodies of water used for Navigability, navigability for shipping. Naturally, channels will change their depth and capacity due to erosion and Deposition (geology), deposition processes. Humans maintain navigable channels by dredging and other engineering processes. By extension, the term also applies to fluids other than water, e.g., lava channels. The term is also traditionally used to describe the Venusian channels, waterless surface features on Venus. Formation Channel initiation refers to the site on a mountain slope where water begins to flow between identifiable banks.Bierman, R. B, David R. Montgomery (2014). Key Concepts in Geom ...

Breda–Rotterdam Railway
The Breda–Rotterdam railway is a heavily used railway line in the Netherlands running from Breda to Rotterdam, passing through Dordrecht. It is also called the ''Staatslijn I'' ("state line I") in Dutch. The line was opened between 1866 and 1877. The railway was opened in phases: * 1 July 1866: - - * 1 January 1872: Lage Zwaluwe - Dordrecht, including the Moerdijk Bridge * 1 November 1872: - Rotterdam Mallegat * 1 May 1877: Rotterdam Mallegat - * 2 December 1878: Rotterdam Mallegat - Rotterdam Feijenoord (goods transport only) Until 1872, transport between Moerdijk and Rotterdam was by ferry. The railway was electrified in 1950. With the opening of the in 1994, the through the centre of Rotterdam became redundant. The railway viaducts and the old over the Nieuwe Maas were subsequently demolished, leaving only the lifting bridge De Hef over the Koningshaven which has been preserved as an industrial heritage site.

Rijksmonument
A (, ) is a national heritage site of the Netherlands, listed by the agency Rijksdienst voor het Cultureel Erfgoed (RCE) acting for the Dutch Ministry of Education, Culture and Science. At the end of February 2015, the Netherlands had 61,822 listed national heritage sites, of which approximately 1,500 are listed as archaeological sites. History and criteria Until 2012, a place had to be over 50 years old to be eligible for designation. This criterion expired on 1 January 2012. The current legislation governing the monuments is the ''Monumentenwet van 1988'' ("Monument Law of 1988"). The organization responsible for caring for the monuments, which used to be called ''Monumentenzorg'', was recently renamed, and is now called Rijksdienst voor het Cultureel Erfgoed (national service for cultural heritage). In June 2009, the Court of The Hague decided that individual purchasers of buildings that were listed as rijksmonuments would be exempt from paying transfer tax, effective f ...

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that can be rotated horizontally around a vertical axis. It has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or one-eighth turn, in order to clear the channel. Small swing bridges as found over narrow canals may be pivo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Brug
''De brug'' (''The bridge'') is a 1928 Dutch documentary silent short film directed by Joris Ivens. This silent film explores the then-newly constructed Koningshaven Bridge in Rotterdam, an elevator railway bridge. The film looks at its structure, mechanisms, complex actions, and the steam-powered trains and ships crossing it. Synopsis Three views of the film camera appear "as if in a technical drawing. It then proceeds to examine the bridge from all angles." The bridge is shown in ultrawide format, then wide, then in close-up, from a train rider's viewpoint. The view shifts to outside the train looking down at the harbor water far below, then to clouds of steam obscuring and revealing the bridge's steel structure. A worker ascends, inspects, observes the surrounding environs, and descends the superstructure. From a vantage point between two train cars coupled together, the countryside flits by as the train makes its way to the bridge. The bridgemaster at the control console ...

Nederlandse Omroep Stichting
The (; NOS or rarely ; ) is one of the broadcasting organisations making up the Dutch public broadcasting system. It has a special statutory obligation to make news and sports programmes for the three Dutch public television channels and the Dutch public radio services. It is funded by the Dutch government.

''Koru'' is a luxury custom superyacht owned by Jeff Bezos, the founder of Amazon (company), Amazon. The vessel was built in the Netherlands by Oceanco starting in 2021, and delivered in April 2023. It is a three-masted sailing yacht long with a navy blue hull. The superyacht is reported to have cost at least US$500 million, and to require annual maintenance costs of at least $30 million. When commissioned, the yacht was the second-largest sailing yacht in the world, after Andrey Melnichenko (industrialist), Andrey Melnichenko's A (sailing yacht), Sailing Yacht ''A''. ''Koru'' and De Hef In 2022, Rotterdam announced that the city's historic De Hef bridge would be temporarily partially dismantled to allow the yacht to pass through. This move was controversial because the bridge is a Rijksmonument, Dutch national monument owing to its history. Eventually the dismantling plan of the 'De Hef' bridge proved to be unnecessary; the masts were stepped when the vessel was moored dow ...
