MEGATRO high voltage GUYED pylons defination
MEGATRO's high voltage GUYED pylons defination
towers are secured with a pivot base and can reach heights up to 1, 100 feet. MEGATRO's all welded design provides maximum tower stiffness, minimum twist/sway and bending. Towers come with integral wave guide clips and climbing ladder and come with heavy duty guy cable and hardware.
MEGATRO's guyed towers can accommodate a variety of broadcasting, cellular, and microwave antennas. Besides, MEGATRO guyed tower also used in power transmission line project. MEGATRO also offers a wide variety of accessories and mounts.
After fabrication all guyed 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 guyed tower and masts design with below requirements
Design Requirements and Basic of Design
MEGATRO 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 British Standard (hereinafter called BS), Japanese Industrial Standard (hereinafter called JIS) or equivalent standards. The permissible stress of the materials will comply with BS, standard by Architectural Institute of Japan (hereinafter call AIJ) 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.
