Emley Moor Transmitter
History
The current tower is the third structure to have occupied the site. The original 135 meters (443 ft) tower was erected in 1956 to provide independent news television broadcasts to the Yorkshire region. He was replaced in 1964 by a larger 385.5 meters (1,265 ft) guyed mast (identical to the structure still standing in Belmont in Lincolnshire).
the collapse of the mast
Emley Moor has been used as a transmission site since the early days of television transmission. The first transmitter permanent building there was a ITV transmitter, which covers much of the North. He used a tower 135 meters network, which provided only limited coverage. The site's performance was improved in 1966, in anticipation of the color PAL signals when 385 meters of the mast supported tubular Guy was erected, constructed from curved steel segments to form a 2.75 meters (9 feet ) diameter pipe, 275 meters (902 feet) long. This was overcome by a section of 107 meters high made of wire and a cylinder cap, bringing the total height to 386 meters (1266 feet). At the time of its construction, it was one of the highest structural position in the world. It has been designed and manufactured by BICC by EMI.
The cylindrical steel mast became coated in ice regularly during the winter months, ice, and also formed large icicles on the shrouds, placing them under much more pressure. The son of Guy passed over several small roads, and melting ice has led to reduced risk of ice. For this reason, the red warning lights were placed on the tower for use in times of falling ice, with signs on nearby roads crossing guy.
On March 19, 1969, a combination of strong winds and the weight of ice that had formed around the top of the mast and guys brought the structure down. The duty engineer wrote the following in the log of the station, which demonstrates that failure of the structure was completely unexpected:
Day: Lee Vander Byl Caffel,
Ice Ice hazard - Packed begin to fall from the mast and stays. The roads near the station temporarily closed by the boards. Please notify counsel when the roads are safe (!)
Pye follow - no framing - V10 replaced (INS low). Monitor overheating due to fan cluttered dust cleaned, lubricated motor and fan blades reset.
Evening: - Glendenning, Netherlands, Redgrove
1265 ft (386 m) mast: - Fell through Jagger Lane (corner of Common Lane) at 5:01:45 p.m.. Police ITA HQ, RO, etc., all notified.
Mast Power Isolator: - fuse removed and locked in the isolator "off" position. All power pole insulators strain basement was also extinguished. Dehydrators and Tx off.
The wreck of the Emley Moor mast, which crashed in March 1969, scattered in fields.
The collapse left sections of the mast bent littering the area around the transmitter site and through several small local roads. Although one of the guys falling off through a local church and debris were strewn all over the transmitter site, no one was injured in the collapse. The noise was heard for several miles. The collapse completely disabled the transmitter UHF VHF BBC2 and ITV, leaving several million people without service. BBC1 VHF television transmissions continuous transmitter near Holme Moss. The owner of a collapsible mast ITA emergency, 61 meters high, and he quickly moved to Emley transmitter ITA Lichfield so that some services could be restored. ITV signals have been restored to 2.5 million viewers in just four days. The BBC has provided a mobile mast on a broadcast van outside, which has been used to restore a limited service BBC2 colors in just two days. The ITA has purchased a temporary mast to a Swedish company. A Polish team of editors, with Jozef Miciak (1925 - 2008) in charge, were hired and a mast of 204 feet was erected in just under 2.
