Heli-logging
As a heli-logging ( dt .: helicopter harvesting ) refers to the removal of logs from the forest to the assembly station by means of helicopter . This method is particularly useful in regions that are difficult to access, e.g. B. in the mountains, used. In this case, the log is hanging on a long cable below the helicopter moved .
There are two different approaches. With traditional heli-logging, the wood is first felled and prepared for transport before the helicopter arrives. This is then only responsible for the removal. With the so-called standing stem method, the standing tree is first freed of branches by climbers and then sawed at the base so that it just remains standing. The helicopter then flies to the tree, grabs it with a grapple called a grapple, tears or kinks it and flies the trunk straight out of the forest.
The advantage of this method is that no access roads are necessary, as well as protection of the soil and the surrounding trees. The dependence on the weather and the high fuel consumption of the helicopter prove to be disadvantageous.
