发明名称 APPARATUS FOR WINCH (CABLE) LOGGING OF TIMBER
摘要 FIELD: forestry, in particular, logging equipment. ^ SUBSTANCE: apparatus has winch with at least two drums for pulling and return cables, respectively, said cables defining closed contour extending through main guiding pulley system. Logging single-axle wheeled cart and choking equipment are positioned between pulling and return cables. Wheeled cart has load-bearing shield pivotally mounted on cart and system of auxiliary guiding pulleys for pulling cable. Boom-type frame is mounted on wheel axle of cart. Levers are mounted on frame first boom oriented to main guiding pulleys of pulling cable for restricted pivoting in longitudinal-vertical plane. Load-bearing shield fixed on lever free ends is oriented toward frame second boom, in particular, to choking equipment zone. Stop is positioned on outer surface of shield in shield and lever junction zone. One of auxiliary guiding pulleys of pulling cable is mounted on stop through vertical poles, while other auxiliary guiding pulleys are mounted on frame boom oriented to main guiding pulleys for pulling cable. Main guiding pulley system is provided with auxiliary cable centering pulleys for centering of cable relative to axis of related drum. Centering pulleys are positioned on winch base, forward of system of main guiding pulleys defining closed cable contour for moving carts. ^ EFFECT: enhanced reliability in operation and increased efficiency. ^ 6 cl, 7 dwg
