   <abstract xml:lang="ru">
    <p>Известно, что вертикальная нагрузка на трелевочный трактор зависит от размерных характеристик трелюемых хлыстов, и равняется весу прогнувшейся части хлыста от комлевого среза до точки отрыва от поверхности земли и изгибающего момента. Для определения веса погруженной части, учитывается распределение массы по длине хлыста, плотность древесины, модуль упругости и силы трения хлыстов в пачке. Для упрощения расчет производился при следующих допущениях: образующую стволов принимаем, как образующую тела вращения (усеченный конус); плотность древесины равномерна по объему той части хлыста, которая рассматривается в данный момент.</p>

    <p>It is known that the vertical load on the skidder including depends on the size characteristics hauling felled trees. In this case vertical load on the tractor is equal to the weight having caved in portion trees portion by the lower part of the tree cuta-way to the point of lifted from the ground surface and bending moment. For a determination of the weight the immersed por-tion is accounted distribution of mass along the length of felled trees wood density, modulus of elasticity and the friction force in felled trees the bundle. To simplify the calculation was performed at the following assumptions: a generator trunks accept how to defining body of revolution (truncated cone); wood density is uniform over the volume of that part of felled trees which is seen currently.</p>
