7. Erection of the turbine
Step 1: Lifting the tower
1. Check that you have performed all previous steps and that all the parts are firmly connected
together. Check that the gin-pole is connected to the 1
st
segment. Check that all the shackles
and cables are firmly secured to the segments, gin-pole and lifting equipment. Clear all the
uninvolved persons from the area.
! IMPORTANT:
Never stand near or under the tower or
gin-pole when raising or lowering the tower.
2. Make sure that the wires are ran through the hole for wires and that during lifting they cannot
move between the tower 1
st
segment and the base plate.
! HINT:
Fix the wires with the cable ties to one of the M27 threaded bars.
3. Raise the tower slowly
– carefully observing the tension in the cables. If your lifting equipment
does not have enough power or begins to slip, stop the lifting process immediately and gently
lower the tower back to the ground. DO NOT perform any pumping movement to gain more
power.
4. Raise the tower until nearly vertical but with tension still on the lift cable (see Figure 22).
Second person can now catch the gin-pole and lower it gently to the ground by applying
downward pressure. Do not allow the gin-pole to crash to the ground, this will but serious
strain on the system.
! IMPORTANT:
Continue applying pressure on the gin-pole, till at least
2 tower bolts are fixed. Remember that now more pressure is required, as the system is much
heavier with the turbine.
