Detailed Description
WIRELESS TOWER Wireless towers have sprung up across the land with increasing regularity in recent years, with cell phone and Internet providers striving to eliminate dead spots in their coverage areas. Most people see the towers and pay them little heed. Not all wireless towers are the same, however. They come in three basic types. Lattice WirelessTower • A lattice wireless tower is favored in many instances because of its flexibility; it also will withstand heavy loads better than other style towers. Typically, lattice wireless towers have three sides that are latticed, hence the name. Four-sided lattice towers have also come into usage in recent years. Monopole WirelessTower • Monopole towers resemble flagpoles. A monopole tower is but a single pole upon which wireless antennas are mounted. An advantage of a monopole tower is that it is inexpensive to put in place. Monopole wireless towers, however, are somewhat flimsy, and are generally limited in height to 200 feet maximum, making them unsuitable to the needs of some wireless carriers. Guyed WirelessTower • A guyed wireless tower maybe comes to mind for most people when they think of a wireless tower; the style has been in use for many years by radio and television stations. Guyed towers, which are supported by guy wires, are the largest in use, rising some 300 feet or more from the landscape. Until the arrival of monopoles, they were the least expensive wireless tower option. One drawback with guyed towers is that they require a large footprint. MEGATRO is the professional manufacturer of wireless tower over more than ten years. We have supplied too many types of wireless tower to Africa, Asian countries, and south American countries. Our professional team provides ongoing support in the field. From site walks to site maintenance, we specialize in getting sites on air and maintaining operational integrity. Our wireless 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. MEGATRO provide wireless tower design with below requirements Design Requirements and Basic of Design MEGATRO TOWERS will guarantee the overall safety of the tower. MEGATRO TOWERS will submit design calculation report for member design of tower and overall structural stability of the structure, which is signed by a charted structural Engineer. MEGATRO will supply the skeleton to scale, showing the assembly of the structures, the antenna mounting levels, other detail drawings etc. The calculation method to be adopted for tower design will be decided by MEGATRO TOWERS with the consent of the client. All materials will comply with G, BS, ASTM or equivalent standards. The permissible stress of the materials will comply with GB BS, or equivalent. The standards adopted for all materials will be stated separately. General Design Criteria Mast 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 runway Feeders Platforms and guard rails Ladder and ladder guards MEGATRO submit the complete data showing the drag factor from various angles of wind on the antenna offered. Other information: Port of Loading: Qingdao Port Lead Time: One month or based on the customer needs Performance Standard Besides conform to the drawing and design, the materials and fabrication of tower components shall conform to Chinese Standard or other international standard. Payment: TT, LC Origin: Shandong, China Minimum Order: 1 set Packaging: Export standard package Inspection: In house or their party inspection Samples: Charge
