The development of technologies and equipment that meet modern requirements of forest preservation and a gentle mode of forest exploitation becomes a relevant issue within the framework of the implementation of the sustainable forest management principles both at forestry enterprises and in the organization of forestry. Such technologies include developed and field-tested experimental methods of logging using balloon-rope systems for various types and methods of felling. Of particular interest is the concept of using this equipment based on the purpose logging and the environmental and forestry requirements for their implementation. The paper has informative and cognitive nature; its purpose is to provide professionals with information on new technologies and designs of specialized equipment to ensure a gentle mode of forest management and forest exploitation. The article presents the results of theoretical research on possible directions of use of balloon-rope systems when working on forest sites of specially protected natural areas. The authors propose the designs of specialized equipment for the vertical removal of trees (whips) in the process of intermediate felling on the areas with signs of hard access and ecological dependence. Such mechanisms will significantly reduce energy costs when removing branches and limbs from a standing tree and its vertical removal from the plantation. The developed designs of specialized mechanisms for skidding a vertically standing tree without its landing in the form of a grabbing, grabbingcutting and knot-cutting device with a grabber ensure the maximum possible preservation of the forest environment, since they do not cause damage to the nearby stand, the undergrowth or the soil.
