5. Erection the of tower
Before starting the tower erection, following steps must be completed:
1. The foundation has been manufactured according to appendix 02 and has had at least 28
days to cure.
2. All the parts have been inspected and unpacked and deemed to be of right quantity and
quality.
3. All the tools have been acquired and their presence has been verified.
Step 1: Placing the tower base plate
1. Place four pairs of M27 nuts onto the M27 threaded bars and place A 28 washer on top of
each pair (see Figure 3). Adjust the upper nut surface to roughly 95 mm from the foundation
surface. Use WD-40 oil to lubricate the nuts before placing them on the bars.
2. Place the tower base plate onto the washers and use a spirit level to level the base plate in
the horizontal plane. Do so by turning the upper M27 nuts up and down as far as needed.
! HINT:
Do not push the bottom nuts against the upper nuts before levelling out the base
plate. This will make the adjustment process faster. Take not of the base plate placement in
terms of lifting equipment to have enough space available at the right sides.
3. Place A 28 washer onto each threaded bar and on top of the base plate.
4. Place M27 nuts onto each threaded bar and fix them cross wise with a torque of 1080 Nm,
going first 50% and then 100%.
5. Push the bottom counter nuts against the upper nuts and fix them with a torque of 540 Nm.
