The advantages are described, as well as the possibilities inherent in timber tractors with trailers-dissolutions to achieve high technical and economic indicators, significantly exceeding those of single timber vehicles, as well as other comparable layouts of timber haulers. The analysis of the scientific works of foreign authors was carried out, which made it possible to identify the most significant factors on which the efficiency of the process of hauling long-length timber products by timber tractors with dissolution trailers depends. The existing conditions for the hauling of long-length timber in the Russian Federation by timber tractors with a trailer, as well as the negative consequences of their operation in difficult road and climatic conditions, are considered. It has been established that the insufficient equipping of logging roads is accompanied for logging road trains by a forced unsteady mode of movement, which leads to failure due to the impact of alternating loads from the side of the trailer-dissolution with timber of the pivot assembly of the rotary conic devices of a timber tractor. In order to increase the efficiency of timber tractors with trailers-dissolutions, as well as to minimize the negative impact on the pivot assembly of alternating loads from the inertia forces of the trailer-dissolution with timber materials, a promising scheme of a recuperative spring-hydraulic rotary conical device is proposed. The necessary and sufficient tasks for the creation and practical use of the proposed device are formulated.
