We offer comprehensive solutions to match the special requirements of each organization, aiming for absolute customer satisfaction. All our communication mobile towers are marked by quality construction and superior strength, and are suitable for a wide range of demanding applications in communication infrastructure.MEGATRO provide every type of lattice steel tower & mast for communication mobile application. These towers are, typically, tall structures designed to support telecom accessories with antennas (also known as aerials) for telecommunications and broadcasting, including television, antenna and other supports, which also can accommodate a variety of disc with network parts. MEGATRO also offers a wide variety of accessories and mounts.Our communication mobile tower is fabricated by solid steel pipe with angle or bracing members, which provides great strength, low weight and wind resistance, and economy in the use of materials. Lattices of triangular cross-section are most common, and square lattices are also widely used. After fabrication all towers are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.Radio masts and towersare, typically, tall structures designed to supportantennas(also known as aerials) fortelecommunicationsandbroadcasting, includingtelevision. There are two main types: guyed and self-supporting structures. They are among the tallest man-made structures.Masts are often named after the broadcasting organizations that originally built them or currently use them.In the case of amast radiatoror radiating tower, the whole mast or tower is itself the transmitting antenna.Mast or tower? A radio mast base showing how virtually all lateral support is provided by the guy-wiresThe terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting orcantileveredstructure, while amastis held up by stays orguys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in the transmission of mobile telecommunications. Masts (to use the civil engineering terminology) tend to be cheaper to build but require an extended area surrounding them to accommodate the guy wires. Towers are more commonly used in cities where land is in short supply.There are a few borderline designs that are partly free-standing and partly guyed, calledadditionally guyed towers. For example:TheGerbrandy towerconsists of a self-supporting tower with a guyed mast on top.The few remainingBlaw-Knox towersdo the opposite: they have a guyed lower section surmounted by a freestanding part.Zendstation Smilde, a tall tower with a guyed mast on top (guys go to ground)Torre de Collserola, a guyed tower with a guyed mast on top (tower portion is not free-standing)Materials Typical 200 foot (61 m) triangular guyed lattice mast of an AM radio station inMount Vernon, Washington, USASteel latticeThe steel lattice is the most widespread form of construction. It provides great strength, low weight and wind resistance, and economy in the use of materials. Lattices of triangular cross-section are most common, and square lattices are also widely used.Guyed mastsare often used; the supportingguy linescarry lateral forces such as wind loads, allowing the mast to be very narrow and simply constructed.When built as a tower, the structure may be parallel-sided or taper over part or all of its height. When constructed of several sections which taper exponentially with height, in the manner of theEiffel Tower, the tower is said to be an Eiffelized one. TheCrystal Palacetower inLondonis an example.Russian TV tower,PenzaTubular steelGuyed mastsare sometimes also constructed out of steel tubes. This construction type has the advantage that cables and other components can be protected from weather inside the tube and consequently the structure may look cleaner. These masts are mainly used for FM-/TV-broadcasting, but sometimes also as mast radiator. The big mast ofMühlacker transmitting stationis a good example of this. A disadvantage of this mast type is that it is much more affected by winds than masts with open bodies. Several tubular guyed masts have collapsed. In the UK, theEmley MoorandWalthamTV stations masts collapsed in the 1960s. In Germany theBielstein transmittercollapsed in 1985. Tubular masts were not built in all countries. In Germany, France, UK, Czech, Slovakia, Japan and the former Soviet Union, many tubular guyed masts were built, while there are nearly none in Poland or North America.Other types of antenna supports and structures[edit]PolesShorter masts may consist of a self-supporting or guyed wooden pole, similar to a telegraph pole. Sometimes self-supporting tubulargalvanized steelpoles are used: these may be termedmonopoles.BuildingsIn some cases, it is possible to install transmitting antennas on the roofs of tall buildings. InNorth America, for instance, there are transmitting antennas on theEmpire State Building, theWillis Tower,4 Times Square, andOne World Trade Center. The North Tower(1WTC)of the originalWorld Trade Centeralso had a 360-foot (110m) telecommunications antenna atop its roof, constructed in 1978-1979, and began transmission in 1980. When the buildings collapsed, several local TV and radio stations were knocked off the air until backup transmitters could be put into service.[2]Such facilities also exist inEurope, particularly for portable radio services and low-powerFMradio stations. InLondon, theBBCerected in 1936 a mast for broadcasting early television on one of the towers of a Victorian building, theAlexandra Palace. It is still in use.Disguised cell-sites Completed in December 2009 at Epiphany Lutheran Church in Lake Worth, Florida, this 100' tall cross conceals equipment forT-MobileMany people view barecellphone towersas ugly and an intrusion into their neighbourhoods. Even though people increasingly depend upon cellular communications, they are opposed to the bare towers spoiling otherwise scenic views. Many companies offer to 'hide' cellphone towers in, or as, trees, church towers, flag poles, water tanks and other features.[3]There are many providers that offer these services as part of the normal tower installation and maintenance service. These are generally called "stealth towers" or "stealth installations", or simplyconcealed cell sites.The level of detail and realism achieved by disguised cellphone towers is remarkably high; for example, such towers disguised as trees are nearly indistinguishable from the real thing, even for local wildlife (who additionally benefit from the artificial flora).[4]Such towers can be placed unobtrusively innational parksand other such protected places, such as towers disguised ascactiinCoronado National Forest.[5]Even when disguised, however, such towers can create controversy; a tower doubling as a flagpole attracted controversy in 2004 in relation to theU.S. Presidential campaign of that year, and highlighted the sentiment that such disguises serve more to allow the installation of such towers in subterfuge away from public scrutiny rather than to serve towards the beautification of the landscape.[original research?][6]Disguised cell sites sometimes can be introduced into environments that require a low-impact visual outcome, by being made to look like trees, chimneys or other common structures.Mast radiatorsMain article:Mast radiatorA mast radiator is a radio tower or mast in which the whole structure works as an antenna. It is used frequently as a transmitting antenna forlongormedium wavebroadcasting.Structurally, the only difference is that a mast radiator may be supported on an insulator at its base. In the case of a tower, there will be one insulator supporting each leg.Telescopic, pump-up and tiltover towersMain article:Cell on wheelsA special form of the radio tower is thetelescopic mast. These can be erected very quickly. Telescopic masts are used predominantly in setting up temporary radio links for reporting on major news events, and for temporary communications in emergencies. They are also used in tactical military networks. They can save money by needing to withstand high winds only when raised, and as such are widely used inamateur radio.Telescopic masts consist of two or more concentric sections and come in two principal types:Pump-up masts are often used on vehicles, and are raised to their full height pneumatically or hydraulically. They are usually only strong enough to support fairly small antennas.Telescopic lattice masts are raised by means of a winch, which may be powered by hand or an electric motor. These tend to cater for greater heights and loads than the pump-up type. When retracted, the whole assembly can sometimes be lowered to a horizontal position by means of a second tiltover winch. This enables antennas to be fitted and adjusted at ground level before winching the mast up..General Design CriteriaMast will be designed based on GB, BS 8100, TIA/EIA-222-G-2006, IS 802 & IS875 or equivalent international standards.The wind loading on the tower and antennas mounted on it will withstand a ground level wind velocity of 140 Km/h and survival speed of 180 Km/h including with height in accordance with latest BSI CP3: Chapter V: Part 2: British Standard (BS)Antenna that will be considered when it calculates wind areas will be Six GSM antennas, Two each 600 mm diameter microwave dishes & one 1.2m Ø Microwave plus all the feeders for GSM and MW antennas.Allowance will be given to the effective windage area of the following:Feeder runwayFeedersPlatforms and guard railsLadder and ladder guardsMEGATRO submit the complete data showing the drag factor from various angles of wind on the antenna offered.Other information:Port of Loading: Qingdao PortLead Time: One month or based on the customer needsPerformance StandardBesides conform to the drawing and design, the materials and fabrication of tower components shall conform to Chinese Standard or other international standard.Payment: TT, LCOrigin: Shandong, ChinaMinimum Order: 1 setPackaging: Export standard packageInspection: In house or their party inspectionSamples: Charge
