Stacking the 4-Leg Tower Section
The following is a general procedure for stacking sections of a 4-leg tower.
Before You Begin
Assemble all the required 4-leg tower sections on the ground. Square each section and tighten all hard-
ware before stacking.
DANGER
Follow all safety procedures when hoisting equipment. Wear hard hats and make
sure everyone is clear of the working area.
1. Hoist the first 4-leg section (A) and place them on the foundation anchors.
NOTE:
After the section has been anchored to the foundation, tighten all the splice hardware.
2. Hoist the next 4-leg section (B) onto the previous 4-leg section (A) and install using bolts (9), wash-
ers (10) and nuts (11).
NOTE:
After the section has been stacked to the previous section, tighten all the splice hardware.
3. Repeat the previous step to continue installing the remaining 4–leg tower sections until the correct
tower height is reached.
4. If required, attach sealing plates at the top corners of the last 4-leg section, tighten all the splice
hardware. See
for sealing plates.
NOTE:
Sealing the top is job dependent and not supplied in the shipping bundle.
