Abstract

The article proposes a constructive solution for improving the technological process of logging wood with rope skidders under conditions of an extended distance of the primary haulage of wood and a considerable length of a hauling-carrying rope for hilly-ridge and waterlogged production conditions, including for selective felling (especially relevant in the Northwestern Federal District of the Russian Federation , especially in the Leningrad region, where timber harvesting in the forests of the first category predominates). The proposed solution is a double-structure carriage, obtained by connecting the mounting of the travel wheels with two articulated joints, without changing the standard designs of the existing carriages. This design allows the carriage to provide the passage of turns with a bundle of skidded timber on the curved track of the carrying rope. When introducing rope skidders with articulated carriage (SHSK), the possibility of turning the track will expand the area of the available logging fund. The use of cable scudding systems with SHSK will allow organizing skidding routes, without significant wear of the ropes, with turning angles up to 45 degrees.
