The invention relates to a method and a device for cutting off the trunk of a tree by detonation of an explosive charge in contact with the trunk. The invention solves the problem of providing a safe and convenient way of cutting off the trunk of a tree which has fallen to an inclined position where it rests against another tree or against an electric overhead line. To the trunk there is, at the desired level above ground, attached a holder which carries an explosive charge and can from the ground be mounted on the trunk, whereupon the charge is detonated and the trunk section above the cut-off level severed from the section below. In this way the top section is either directly released from its support or can conveniently be so released.

La présente invention a trait à une méthode et à un dispositif pour couper les troncs d'arbres par explosion d'une charge explosive placée en contact avec le tronc. Grâce à cette invention, on peut facilement et sans danger couper le tronc d'un arbre tombé en position inclinée contre un autre arbre ou contre une ligne électrique aérienne. On attache au tronc, au niveau voulu au dessus du sol, un collier contenant une charge explosive, que l'on peut, depuis le sol, fixer sur le tronc au niveau voulu. On fait alors exploser la charge et on détache du segment inférieur le segment de tronc au dessus du niveau de coupe. Cette méthode permet, soit d'arracher directement le segment supérieur à son support, soit de l'en détacher facilement.
