APAC's modular aluminium lattice towers are manufactured locally in Queensland in 3.1 metre sections allowing effortless transport, meaning total leadtime can be measured in days - not weeks or months. As an ultra-lightweight structure the towers can be built with a small crew and minimal plant, with smaller towers even able to be assembled by hand.
These modular lattice towers consist of a large rotatable base plate, modular 3.1 metre lattice sections, guy wires, anchor footings/skids, and your choice of headframe. The 3.1 m sections are easily stacked meaning radio towers can be built as small as 3.1 metres with full structural engineering certification up to 41 metres (30.7 metres in Wind Region C). APAC's AL220 aluminium lattice modules feature three upright columns made from 50x4 CHS with 32x3 CHS lattice welded in between by certified boom welders, providing incredible strength while retaining a lightweight design that can support your technician to climb the full height.
The ground mounted AL340 towers specify the use of Surefoot footings for simple, straightforward installation. Concrete cages and other options are available on request.
Headframes are available to support a range of wind turbines, radars, camera systems, and telecommunications configurations. Torque Arms (anti-twist) available for applications requiring large microwave antennas, or systems with large offsets.
