Abstract
There is provided an ascension aid for a wind turbine comprising a cabin, a catch unit which co-operates with a securing cable as a securing means and a testing unit for testing the functionality of the catch unit. The testing unit has a base plate, a closure counterpart holder, a closing member and an actuating element coupled to the closing member. By actuation of the actuating element the closing member and the closure counterpart holder clamp the securing cable and the closing member and the closure counterpart holder move upwardly along the base plate. Upon release or de-activation of the actuating element the closing member releases the securing cable and the catch unit trips.
Claims12
An ascension aid for a wind turbine, comprising:
- a cabin;
- a catch unit that co-operates with a securing cable to secure the cabin and to prevent the cabin from moving unexpectedly downwardly;
- and
- a testing unit for testing the functionality of the catch unit,
- wherein the testing unit has a guide unit for the securing cable and an entrainment unit for the securing cable, wherein the entrainment unit is suitable for pulling the securing cable upwardly,
- wherein the guide unit has a base plate,
- wherein the entrainment unit has a closure counterpart holder, a closing member, an actuating element coupled to the closing member, wherein the actuating element is a cable pull, wherein the closing member is coupled to a first end of the cable pull, wherein a second end of the cable pull extends into the cabin,
- wherein by actuation of the cable pull:
- the closing member and the closure counterpart holder clamp the securing cable, and
- the closing member and the closure counterpart holder are moved upwardly along the base plate,
- wherein the catch unit trips upon actuation of the actuating element, and
- wherein upon release of the cable pull, the closing member releases the securing cable.
