断装置に関するものである。[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention is applicable only to the work of cutting off the head of standing trees and pruning, which is a problem that occurs near power transmission lines, distribution lines, communication lines, etc. The present invention also relates to a tree cutting device that is used for head-cutting, pruning, felling, etc. of general forest trees, street trees, garden trees, etc.
(従来の技術)
従来の立木頭止切り、枝打ち等の切断作業は作業者が切
断対象樹木にたてかけた脚立や梯子に登り、なたや鋸を
用いて実施するというものであった。(Prior Art) Conventionally, cutting operations such as cutting off the head of a standing tree and pruning have been carried out by a worker climbing a stepladder or ladder placed against the tree to be cut, and using a machete or a saw.
切断対象樹木が高い場合には、作業者が脚立や梯子から
さらに樹木の梢までひっだ一トで、同じく切断作業を実
施していた。If the tree to be cut was tall, the worker would use a stepladder or ladder to reach the top of the tree to carry out the cutting work.
(発明が解決しようとする問題点)
しかし、地面が凹凸又は軟弱である場合には脚立や梯子
が不安定になったり、極端な場合には使用できなくなっ
たりするという問題がある。(Problems to be Solved by the Invention) However, if the ground is uneven or soft, there is a problem in that the stepladder or ladder becomes unstable or, in extreme cases, becomes unusable.
地面が平らでしつかりしている場合には脚立も梯子も使
用できるが、樹木が高い場合には脚立等が届かないので
対象樹木の高さに制限が出てくる。Stepladders and ladders can be used if the ground is flat and firm, but if the trees are tall, stepladders cannot reach them, so there is a limit to the height of the target tree.
そこで、高木では前記の通り作業者が不安定な梢に登っ
て切断作業をすることになるが、高所作業であり、足場
も極めて悪いので、作業がはかどらず、墜落する危険も
ある等の問題があった。Therefore, as mentioned above, in the case of tall trees, workers have to climb the unstable treetops to perform the cutting work, but because the work is done at a height and the footing is extremely poor, the work does not proceed smoothly and there is a risk of falling. There was a problem.
