FORESTRY WINCH WITH SOPHISTICATED PROTECTION WHILE GUIDING THE TOW ROPE IN THE AREA OF UPPER PULLEY

摘要

The invention relates to a forestry winch (1) with advanced protection while guiding the tow rope (10) in the area of the upper pulley (2). Said pulley (2) is provided with a guide (23) of a draw rope (10) comprising a guide sleeve (231) disposed at a radial distance from the outer circumference of said draw rope (22) through which a draw rope (10) is inserted for guiding purposes. 10). Said guide sleeve (231) fastened to a pair of arms (232, 233) disposed on each side of said rope (22) together with said guide sleeve (231) at least as defined as relative to the upper pulley housing (21) (21). 2) rotating about said horizontal geometric axis (20 "), around which the said rope (22) is also rotatable. The rotation angle of said guide (23) about said horizontal geometric axis (20") is at least 100 degrees or. is at least such that the tow rope (10) through said guide sleeve (231) in the direction of the respective load can either be inclined obliquely inward from the base or downward at least approximately perpendicularly to the base. In the area between the housing (21) of the upper pulley (2), namely in the area near the rope (22) and through the latter running rope (10), and the guide (23) of the rope (10), a rope guard (3) is mounted (10), which is fixed on one side to said housing (21) and, on the other, to said guide (23), so that at least substantially the gaps in the circumferential direction of the rope (22) close the gap between the upper housing (21) housing (21). 2) and the guide (23) of the tow rope (10) on the upper pulley (2).
