T3a Heavy Duty Tower
Larger antennas
More ancillary equipment
Higher windspeeds
T3a
The new heavy duty lattice tower, designed for larger 5G antennas, more ancillary equipment and for areas with higher windspeeds. The T3A is ideally suited for site sharing.
Heights: 15m - 50m in 2.5m increments.
Tower includes internal ladder, Latchway Fall Arrest, anti-climb protection, feeder brackets and lightning finials along with various headframe options.
Headframes For The T3a
The illustrations show ring headframes with internal flooring for safer working at height. Leg and face mounting frames are also available.
Head frames can be designed for 5G loading, mounting at various heights, with multiple levels for site sharing.
Screwpile & Micropile Foundations
FLI’s steel grillages with either screw piles or micropiles are more compact than their equivelant in mass concrete. These foundations can enable tower upgrades to be accommodated within existing site boundaries and installed around existing concrete bases. Generally, screw piles are used in softer ground and micropiles for bedrock, legacy concrete and other hard ground conditions.
For towers with larger face widths it becomes more efficient to distribute the forces through individual leg frames rather than a unified grillage. These leg frames can be mounted onto either micropiles or screw piles depending on ground conditions.
