Step 3: Placing the tower 2
nd
segment
1. Place the tower 2
nd
segment bottom against the 1
st
segment top (see Figure 6). The 2
nd
segment weighs about 145 kg, therefore a lifting aid in form of a tractor, fork lifter or a crane is
necessary to perform the operation. Use synthetic lifting slings to make contact with the tower
2
st
segment in order not to damage the zinc layer.
! IMPORTANT:
Make sure you DO NOT
place any body part underneath the lifted object while it is being lifted. Make sure that the
segment lifting eye is facing upward direction.
2. Fit eight M20 x 45 bolts with a spring washer and then a regular washer and place the bolts to
join the two segments. Use WD-40 oil to lubricate the bolts before placing them into the
threaded holes. Fix the bolts cross wise with a torque of 434 Nm, going first 50% and then
100%.
! TIP:
When having trouble getting bolts into threads, rock the segment slightly up and
down.
