7. Instructions & Precautions before starting and during Operation
Operators must wear a safety harness
and connect the safety hooks to the yellow fixing
points provided on the platform.
Means of communication, (Mobile Phone) must be available on the platform.
It is recommended to have an Emergency rappelling kit on the platform.
Make sure that the blades are in the parked (stand still) position with one of the blades
pointing down vertically, and that the brakes are on.
Platform may only be used not guided when the wind speed is less than
10 m/sec
.
Double check the wind speed before starting.
If using a tag line, the platform may be used only when the speed is up to
12,5 m/sec
.
A stand-by person or team members must be available on the ground for emergency
cases or to handle the tag line when the wind speed is more than
10 m/sec
.
It is possible to have increased wind speed during operation on the blade. As long as the
platform is over the blade there is no problem. In case the platform needs to be operated
down, at least one tag line is required, fixed on the safety hook attachment point at the
rear of the platform on the wind side, and lowered to the ground for the ground team to
give the relevant amount of pulling force to keep the 2 rollers in contact with the turbine
tower. Therefore a tag line of sufficient length should be on board of the platform during
each operation.
Because the stirrups are located towards the inside of the tower, the BAP will tend to tilt
away from the tower on initial lift off. This is normal and to be expected. As the platform is
pushed away from the tower the platform will tend to level out. It is recommended to raise
the platform off the ground and immediately position the sub frame to the middle position.
In case the wind speed is close to the maximum value of 10m/sec, the sub frame must be
repositioned to the minimum position bringing the platform closer to the tower. This way
the moment arm for the wind force on the platform will be reduced. The platform might be
tilted slightly backwards in this case.
