High Mast Features
- Mast Structure: Our high mast is continuously tapered, polygonal cross section of at least 20 sides, presenting a good & pleasing appearance which is based on proven in-tension design confirming to the Technical report no. 7 - 1996 of the Institution of Lighting Engineers. UK. To give an assured performance and reliable service. The structure is suitable for loading as per IS 875(Part 3) 1987.
- Construction: High mast is fabricated from steel plates confirming to BS-EN 10025, cut and folded to from a polygonal section, Masts are in two sections for 16 & 20 Mtr. and in three sections for 25 & 30 Mtr. heights having only longitudinal weld confirming to BS 5135/AWS. The mast is provided with a fully penetrated flange which is free from any laminations or incursions. The welded connection of the base flange is fully developed to the strength of the entire section. The base flange is provided with supplementary gussets between bolt holes to ensure elimination of helical stress concentration. for environmental protection of the mast the entire fabricated mast is Hot Dip Galvanized (Single Dip) internally externally, having uniform coating thickness of 85 / 65 microns for bottom / top sections respectively.
- Door Opening: An adequate door opening is provided at the base of the mast. The opening is such that it permits clean access to equipments like winch, cable, wire rope, plug & socket etc. And also facilities easy removal of the winch for servicing.
