2.2.8 Staying on the tower platform and in the nacelle
Before leaving the safety climbing ladder at the upper end and releasing the body harness from the runner, secure yourself with an energy absorber. Anchorage point when leaving the steel tower is an eye welded onto the internal tower wall next to the end of the ladder. Upon stepping out onto the tower platform, secure yourself with the energy absorber to the holding ring mounted around the tower at shoulder level. When climbing up a concrete tower with external ladder, secure yourself directly to the holding ring as soon as you reach the tower platform, before releasing the harness from the runner. When changing the anchorage point always use the second safety hook of the energy absorber to ensure that you are always secured by at least one hook.
When entering or leaving the nacelle the platform hatch (in turbines with concrete towers) must be closed. Anchorage points for climbing into the nacelle are the foldaway ladder and the yellow handrail screwed to the main carrier on the left.
While access hatch or winch hatch are open, all persons inside the nacelle must stay fastened. Other anchorage points are, for example, eyebolts and handles firmly attached to the main carrier or its steel components.
WARNING:
Handles fixed to GRP material are not suitable as anchorage points!
When the nacelle hatches are closed, persons inside the nacelle may take off their body harness.
WARNING:
It is not allowed to remove any safety provisions.
If it is necessary to remove the protective screens in front of the rotating parts, a sufficient distance to the rotor must be kept. As a general rule, all hatch covers must be closed again after passing through.
Dangerous voltage may still be present in the battery cabinets on the generator rotor even when the power has been disconnected. Only specially trained service personnel is allowed to open theses battery cabinets or the rectifiers. Furthermore it is not allowed to step onto the GRP casing of the nacelle through the roof hatch.
The winch may only be used for transporting material, not for persons. The manufacturers of the body harnesses also provide abseiling equipments (equipment for rescuing persons from great heights). With this rescue equipment other persons can be evacuated, but it can also be used to let oneself down. A suitable anchorage point for the abseiling equipment in the nacelle is the winch hook.
The abseiling equipment is not included in the scope of delivery.
2.2.9 Rotor lock
The two locking bolts engage in the rotor of the generator every 30°. If the rotor is not stopped correctly in one of these 30° positions and someone tries to lock the rotor in spite of that, serious damage to the installation may result. Therefore only trained personnel is allowed to lock the rotor by means of the crank handle in the main carrier. Furthermore, the owner and other third parties are not allowed to enter the room around the rotor hub through the generator.
