LOGGING IN SLOPES
To drive as steep as 45 degrees. It is to be compared with really advanced black runs. Åre downhill slope, for example, a slope of 33 degrees. Outside Amelith, a small village located two hours drive south of Hanover, lives Michael Busch and here he runs his forest contracting firm with his brother Burkhard. Twenty years ago, they took over the company from their father.
In the forests outside Amelith await harvesting in extreme terrain. As usual, could be added. For Michael, it is the rule rather than the exception that he works in forests that look like made for really tough skiing.
- There is a great demand for this type of logging. We have two H20-harvesters in the company. The one I have, we bought two years ago and almost immediately we decided to equip it with a winch. – Forests of more flat land is largely harvested in Germany. Now remains the trees in all the slopes, said Michael. Michael´s H20 harvester is equipped with a winch at the rear. The red box mounted at the rear of the machine contains the winch game, but the solution also includes some intelligence, such as the winch is constantly in interaction with the machine moving forward or backward, and at what speed. The cab can also Michael regulate how much traction to be, which depends on the inclination to run and not least how the ground is.
The winch and associated equipment cost of roughly half a million SEK when it was mounted on the machine two years ago. So it is a big investment and the question is obvious: Has it been a good deal? – We get better prices for this type of logging. Exactly how much depends on several factors. Among other things, the number range to handle during harvesting. But generally, it is thus better paid and the answer is that it was a good deal. The main advantage of the winch is that logging in steeply sloped terrain is no longer dependent on the weather. Before Michael bought H20 machine he had a Rottne 5005 and when he felled a lot in this type of terrain.
- But then we could stand still for a fortnight during the worst rainy season. Had we run the terrain had become more or less destroyed, explains Michael. With the winch minimize soil damage. The winch allows the machine basically never slips and it allows vegetation quickly recovering from logging.
