To enable tree felling work to be carried out efficiently and safely to ensure separation distance from power transmission equipment.SOLUTION: A felling device comprises: a support; a cutting mechanism provided on the support to cut down the tree; a tree attachment mechanism that is provided on the support and is attached to a tree, thereby fixing the support to the tree; and a control device and a communication device that remotely control the cutting mechanism and the tree attachment mechanism. The felling device is suspended from an unmanned aerial vehicle and transported to a felling site, the support is fixed to a tree to be felled by remote operation of the tree attachment mechanism, and the cutting mechanism is operated to cut the trunk or branch to be felled. The felling device is suspended from the unmanned aerial vehicle by a sling, and the felling device comprises a hanging mechanism that extends or winds up the sling.SELECTED DRAWING: Figure 2
【課題】送電設備からの離隔距離の確保のため樹木の伐採作業を効率よく安全に行えるようにする。【解決手段】支持台と、上記支持台に設けられ、樹木を伐採する切断機構と、上記支持台に設けられ、樹木に取り付くことにより上記支持台を上記樹木に固定する樹木取付機構と、上記切断機構及び上記樹木取付機構を遠隔操作する制御装置及び通信装置と、を備えた伐採装置を、無人航空機から吊下げて伐採の現場に運搬し、上記樹木取付機構を遠隔操作することにより上記支持台を伐採の対象となる樹木に固定し、上記切断機構を作動させて伐採の対象となる幹又は枝を切断する。伐採装置は、吊り索により無人航空機から吊下げられ、伐採装置は、吊り索の伸長又は巻取を行う吊下げ機構を備える。【選択図】図2
