Conditions and ability to work forest transport systems under the canopy of the stand
The working conditions of the various transport systems including tow hitch (trailers, semi-trailers and dissolutions) for timber skidding when working under the canopy of the stand. Comparison of room for maneuver under the canopy the stand of transport systems with different hitch. Established that the smallest possible turning radius of the transport system consisting of a tractor with a front wheel steering is achieved by the dissolution of its acquisition and the maximum trailer when recruiting for an equal length of the loading platforms. When driving on radial curves broadening corridor necessary for the smooth passage of the transportation system is determined by its total length of the transport system and the minimum at acquisition the dissolution tractor, wheel which follows the path of the tractor rear wheels. Established that the transport system to the advantage of the dissolution, the criterion for the minimum corridor width required for passage, most obviously with a minimum turning radius and increases with the length of the loading platform. At small length of the loading platform to use as a trailer hitch, the least efficient in comparison with other hitch while logging timber under the canopy of the stand. The possibility of the transport system for the movement of timber, which is longer than the length of the loading platform when maneuvering under the canopy of the stand, limited only by the condition of load distribution between the axles of the loading platform.
