LATTICE TOWER DESIGN Project: Development of Tower Profiles and Structural Design of Lattice

Towers ƒ TKM Design, led by DR. Monda, has developed unique Tower Designs formulated from basic Modular Tower profiles that have been modelled in 3D, and simulated in STAAD Pro Analysis Software. ƒ The generated Designs have been optimised and modified regularly to create efficient Towers that lend themselves to simple manufacturing process. ƒ The Towers range from 21 meter Rooftops to 90 meter 3-leg Tubular Towers and 70 meter 4 leg Angle Towers. We continue to continuously refine and improve our Tower Designs. TKM Design has developed and grown a comprehensive Tower database that is a fertile resource base for TKM. ƒ The Designs have achieved significant cost savings and performance milestones for Telcom providers, due to their unique profiles researched over the past 3 years, and have been presented at the annual I.E.K International Engineering Conference.

The TKM Design Team, providing specialised Design and Engineering Support to our Clients, is a unique Strength rarely matched.
