Abstract

The article presents the results of practical and theoretical studies in the field of application of balloon-cable systems capable of operating in the mode of vertical removal of a tree from a forest canopy and its subsequent transportation to a loading point. The relevance of this technological direction lies in the impossibility of traditional forestry equipment to carry out the process of harvesting and transporting wood without violating environmental requirements. It is noted that clear environmental effect can be achieved using air wood harvesting and transportation means, in particular when using balloon systems. A brief description of the operation of the load-gripping cutting mechanism used for the vertical skidding system using balloon-cable systems is given. It is indicated that the main parameters of these mechanisms that affect their effective operation are the mass of the mechanism and the speed of its lowering to the tree crown. The method of calculating the optimal mass of load-gripping cutting mechanism is given depending on the type of wood being processed and the speed of lowering. Brief recommendations for calculating mass and speed of movement with the possible use of an ascending load-gripping cutting mechanism are given
