摘要
The invention concerns a forestry skyline comprising a mobile driving assembly (1) which is adapted to be towed by means of a tractor (T) and a carriage (2), which is movable along a suspension cable (VN). The driving assembly (1) includes a telescopically conceived pylon (11), which is on its first end portion (11') protruding apart from the ground (P) furnished with freely rotatable pulleys (111, 112, 113), and a chassis (13), which is furnished with a pair of wheels (130', 130") and is used for transporting the driving assembly (1). The invention is characterized in that said wheels (130', 130") are each per se pivotally connected with the pylon (11) with the possibility of adjusting the position of each wheel (130', 130") relative to said pylon (11), and in that the second end portion (11") of said pylon (11), which is faced towards the ground (P), is adapted for anchoring of the pylon (11) by means of penetrating thereof into the ground (P) due to the total weight of said driving assembly (1). This allows for appropriate levelling and anchoring of the pylon during opearation of the forestry skyline.
