history

Debris from the steel mast that collapsed in 1969

Since the 1950s there have been transmitters at the location of the television tower on the plateau of the same name in Yorkshire , five kilometers southeast of Huddersfield . Since November 3, 1956, the first system transmitted VHF and television signals . A 135 meter high steel lattice tower was first used for this purpose, which was replaced in 1964 by a 385 meter high guyed tubular steel mast, the tallest structure in Europe at the time. On March 19, 1969, this mast collapsed as a result of heavy icing in a winter storm. The accident led to a total failure of radio and television programs for several million British people; People were not harmed. As a result, several relief measures had to be initiated in order to compensate for the failure of the transmitter. The broadcaster Holme Moss temporarily took over part of the broadcasting tasks. The BBC presented after two days on additional mobile antennas to the broadcast of the station BBC2 ensure. In addition, a 100,000- pound sterling cost was erected on a 204-meter-high transmission tower which went into operation on April 16. A few weeks later, a further temporary structure was built with a 91 meter high mast. Parts of the collapsed tubular steel mast have since served as a control tower in a yacht club near Huddersfield. To replace the collapsed mast and the subsequent makeshift arrangements, a reinforced concrete television tower was completed in 1971 and went into operation on April 21.

description

The 274.32 meter high concrete shaft tapers from 24.4 meters in diameter to about 6 meters and stands on a 6.1 meter deep ring foundation made of sandstone . The tower, which weighs more than 11,000 tonnes, looks like a slender chimney, as its relatively small tower cage is hardly noticeable at a height of 275 m. The tower cage has a diameter of only 6.5 meters with a wall thickness of 35 centimeters. The tower is closed off by a 56 meter high steel antenna. In 2002, the United Kingdom classified the Emley Moor television tower with level 2 of the so-called listed buildings , a list that lists architecturally or historically significant buildings and thus places them under monument protection .
