At the top of this tower was placed a metallic antenna signal transmission for radio and television. The main structure is a hexagonal hollow pillar of steel and concrete containing all six elevators, escalators, connections and power distribution. The CN Tower is composed of several structures. The stations are: CBC Radio and Television, CFTOTV, Global TV, CITY TV, Look TV (Digital), Rogers Cable, Toronto1, TV Ontario AM and FM Radio: Master FM, CFMX, CFNY, CFRB, CFTR, CFYI, CHFI, CHIN, CHUM, CHWO, CILQ, CIRC, CJCL, CJEZ, CJMR, CJRT, CKFM, CKMW, KISS. The tower allows controlled feats: People have jumped dramatically since the summit, climbing through the windows and using motorcycles to climb the stairs. The third area to which the public has access is the Skypod, 447 meters, one of the highest public vantage points in the world.ġ6 radio and television antenna used to transmit their signals.A 351 meters is located a restaurant rotates 360 ° every 72 minutes At 346 meters is the Lookout Level, which is located in the Café Horizon and an observation deck inside.Twelve giant steel supports and wood were slowly raised into position and then be used to create the media on the basis that support the main level. Using 45 hydraulic jacks subject to cables that hung from a steel crown anchored temporarily to the top of the tower. In August 1974, construction began on the main floor. This was already by itself a pretty impressive feat of engineering, consisting of a metal platform that was big on cats, raising approximately 6 meters a day, the same workers advanced meters with concrete underneath. To build the base of the main pillars used a slipform moved hydraulically. Once the pit 15 meters deep, 7000 meters cubic poured concrete, 46 tons of rebar and steel wire 36, creating a wall thickness of 6.7 meters for foundation The CN Tower began construction in February 1973 and was completed in 1976, after 40 months of work. It was built by the state railways, the Canadian National Railway, known by the acronym CN, origin of the name of the tower. It is estimated that the CN Tower weighs 134,193 tonnes It has two water tanks of more than 56,000 liters each that recharge automatically. This rises to the observation deck located 342 meters by an elevator. It opened in 1976 and has the highest metal ladder in the world since 1776 has stairs that climb 147 floors, while a fire escape and is not open to the public. You reach the observation decks, bar and restaurant with fast elevators, which it takes only a minute drive from the base to the Observation Deck Interior. Before completion, the architects added to it a revolving restaurant and observation deck. In the beginning was planned with the aim of placing an antenna high enough to permit the transmission and reception of signals without any interference, especially due to the tall buildings of Toronto. The Tower is easily accessible from Union Station and the streets and major roads. The CN Tower is located at 301 Front Street West in the heart of the Entertainment District, on the north shore of Lake Ontario, Toronto, Canada. People living in the Toronto area now enjoy one of the clearest reception in North America. Helped solve problems that the construction of the CN Tower with its microwave receptors at 338 meters and 553.33 meters antennas. The construction boom that occurred in Toronto in the ’60s not only changed their relatively low buildings skyline dotted with skyscrapers on the other, but also caused serious communication problems. The official opening ceremony took place in October 1976.Īlthough the tower is a source of pride for Canadians and an undeniable tourist attraction, the origin of its construction is closely linked to practical reasons. In 1995 he was ranked as one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. Its construction lasted 40 months and at a cost of 300 million Canadian dollars. With a height of more than 550 metres, the CN Tower was the tallest free-standing structure in the world until the opening of the Burj Khalifa in 2010 with 828 meters became the man-made structure more largest in history.
