Devices for trimming trees in urban areas

Abstract In an urban area, the care of large trees is problematic. When they age, branches, peaks should be trimmed. The use logging machines hampered by their size and also significantly pollutes environment, due to significant emissions harmful substances into atmosphere. addition, felling delimbing process itself not safe, its in environment poses a threat human life, integrity buildings infrastructure. most cases, solve such problems, special workers (arborists) are used, who either climb onto tree trunk, or crane basket cut piece piece. Such technologies costly, unsafe and, at times, can cause inconvenience others. design detailed algorithm for operation device presented, which allows you branches trunks ensure controlled descent ground without people this case, operator controls installation remotely. consists movement mechanisms, chain saw pruning tops, system lowering parts ground. analysis showed that proposed more effective than counterparts arborists.
