Chapter 5: 4-Leg Towers

Assembling the 4-Leg Tower Section (Chevron and Warren
Bracing)

The following assembly procedure can be used for any section with two-bays of chevron and four-bays of
warren bracing. A similar procedure can be used for assembling the different sizes of chevron and warren
bracing 4-leg tower sections.

What You Should Know

You will assemble two completed sides (front and rear) and connect them together to complete the 4-leg
section. Assemble the braces starting from the top working towards the bottom. Square the tower section
and tighten all hardware before stacking.

1. Insert the strut (2) between the shear plates located at the top of the columns (1) and connect them

using bolts (3) and nuts (4).

2. Assemble the two gusset plates (5) to the strut (2) using bolts (3) and nuts (4).

3. Assemble the two diagonal braces (6), aligning the top of each brace to the gusset plates (5) and

the bottom to each column (1) using bolts (3) and nuts (4).
