50m Multifunction 3 Legged Bts Wireless Steel Tubular Mast And
Communication 3g 4g Telecommunication Antenna Tower Guyed wire tower is composed of a tower head, a column, and a
pull-line. The tower head and column are generally composed of
space derivative structure composed of angle iron, which has good
overall stability and can withstand greater axial pressure, and its
pulling wire generally adopts high-strength steel stranding, which
can withstand a large tensile force, so that the wire drawing tower
can make full use of the strength characteristics of the material
and reduce the consumption of the material. However, the pull line
covers a large area, which is not conducive to farmland machine
cultivation, so it is also less used. 3. Technical Data | Design | | 1. Design Code | ANSI/TIA-222-G/F | | 2. Design Wind Speed | Up to 250 km/h | | 3.
