10.2 Preparing Lifting of Blade
Crushing by falling loads!
Risk of crushing by falling load if lifting equipment fails during lifting.
Never stand under a suspended load.
Never expose lifting equipment to loads exceeding the specified safe working
load/working load limit (SWL/WLL) value. Only use lifting equipment designed for the task.
Check lifting equipment visually for damage prior to use.
If replacing parts, only use original parts authorized by Vestas.
Ensure that all cables, chains, slings or other moorings are properly attached
to the load prior to lifting.
Use guiding ropes when situations are endangered by the rotation or
uncontrolled motion of a load.
Always make a test lift before installation/dismantling of blade.
Manual handling!
Injury may result from handling the lift saddle if instructions are not followed.
Do not lift the lift saddle by hand.
Always use forklift when handling the sections.
1. Mount root sling in pos. 1. See Figure 10-11, p. 10

10-10, p. 10
3. Mount the other end of the sling in pos. 2. Figure 10-11, p. 10
Figure 10-10: Attaching the root end with
use of 90 mm webbing
sling on a V112

4. Place the lifting shell in the same radius as the T-section. See Figure 10-12,
p. 11
5. Hook the sling onto the T-section in both sides. Figure 10-15, p. 11
6. Place the attaching saddle on the lifting tool under blade right below the spar.
See Figure 10-13, p. 11
Place an extra piece of friction rubber on the middle of the saddle,

shows a V82 blade
The distance from crane hook to anchor point is approximately 10000 mm.
Lift the blade carefully
Check visually that the root and tip is lifted from the support at the same time.
Check the angel in the root (optimal angel is between 87 and 89 degree.
Install the blade in according to the relevant installation manual
11 Removal of T-Lifting Yoke
Work at height!
When staying or working on the roof or nose cone shell, always use personal
fall arrest equipment (approved full-body harness, lanyard with energyabsorber, positioning rope and fall arrester for wire or rail) and be fastened to
approved (yellow) anchor points on both sides of the nacelle.
When approximately 40 evenly distributed bolts have been tightened, the
lifting yoke can be removed.
Remove the T yoke from blade by detach the sling attach to the hook in the
root end. Pos 2 in Figure 10-11, p. 10
Remove the T yoke with the lift shell carefully out over the tip end and lower
the T-Yoke carefully down.
