TREE-CLIMBING SCAFFOLD
PROBLEM TO BE SOLVED: To provide tree-climbing scaffolds capable of installing readily even to a natural forest tree which is not pruned, the tree-climbing scaffolds also being excellent in safety at the time of use.SOLUTION: A tree-climbing scaffold 1 of the present invention has a holding member 2 which is installed so as to be substantially parallel to the height direction of a tree J and provided with a step-connecting portion 6 in the vicinity of its upper end, a step 3 whose one end is held by the holding member 2 so as to lock a hooked portion 15 on a connecting tool 9, and a logging pulling rope 4 whose both ends are annularly formed and a connecting rope 5.SELECTED DRAWING: Figure 1
【課題】枝打ちされていない自然林に対しても容易に設置することが可能であり、しかも使用時の安全性に優れる木登り足場を提供する。【解決手段】本発明の木登り足場１は、樹木Ｊに対して、その高さ方向と略平行をなすように設置され上端近傍に踏み板連結部６が設けられた保持部材２と、連結具９に鉤状部１５を係止させるようにして保持部材２に一端が保持される踏み板３と、両端が環状に形成された伐採用引きロープ４及び連結用ロープ５を備えている。【選択図】図１
