Summary
| DescriptionAbattage culée noire sapin Molières 17.jpg |
Français : La souche devait être retirée avant de pouvoir construire le nouveau kiosque ; par ailleurs, les matériaux utilisés pour tenter de renforcer la base du tronc empêchaient l’utilisation d’une tronçonneuse. Il a donc été décidé de procéder à un abattage à culée noire, c’est-à-dire un arrachage de l’arbre, afin de l’abattre sans tronçonneuse tout en créant un effet de levier pour arracher la souche. On voit ici la souche séparée de la grume ; une fois la séparation faite, la grume s’est brutalement redressée en retombant dans son trou. Cela explique que l’attention à l’environnement soit primordiale sur un chantier forestier : le photographe s’est laissé surprendre et a failli se faire écraser parce qu’il n’avait pas anticipé cette réaction.
English: The stump had to be removed before building the new kiosk; furthermore, the materials used to try a reinforcement of the trunk prevented using a chainsaw. It was consequently decided to uproot it, to fell it without chainsaw while leveraging the stump to uproot it. One can see here the stump separated from the trunk; once the separation done, the stump suddenly standed up by falling in its hole. This shows why attention to surrounding is so important on a logging site: the photographer was catched out and almost crushed because he didn't anticipated this reaction. |
