If someone should be interested it is, and have been, some yarding in Norway, mostly with pretty small Igland and Owren yarders, but also with austrian equipment like Steyr K15 and K20 (which was a downsized versions of the 046) and Syncrofalke. My friend runs two austrian Konrad yarders today, made for gravity-yarding.
I start with the one of my two Owren T3 yarders, here logging as close as you get to old-growth in Norway, but very small wood, like 3 to 4 trees pr cubic meter. The yarder is a running skyline all hydrostatic double main yarder with a 3-section drum carriage. The system consist of one pump and one motor for each drum, and it is said to be hydraulic interlocked, which I doubt both from a theoretical view and from experience.
