Abstract

The support ladder for cutting trees has a modular frame with a sectional support and ladder, with the sections interengaging and fixed to the trunk by grips. Each pivoting support grips (2) is fixed to the base of the trunk by two straps with the aid of two ratchet reels. The standard sections (1) has three pairs of half straps (16) with a male housing at its base.

L'armature principale est composée d'éléments standards (1) Figure 1 qui s'embo^tent  The main frame is composed of standard elements (1) Figure 1 which fit together

Au fur et à mesure de la mise en place des éléments (1), l'opérateur place des griffes anti dévers (S) tous les trois éléments ce qui les lient au tronc de l'arbre et assure une bonne tenue de l'ensemble. Arrivé à la cime de l'arbre, après avoir placé une dernière griffe anti  As the elements (1) are put in place, the operator places anti-tilt claws (S) on all three elements, which bind them to the trunk of the tree and ensure that the assembly remains in place. . Arrived at the top of the tree, after placing a last anti claw

Un cordage (8) est alors placé dans les roulettes (9) de la potence; une de ses extrémités est accrochée à la griffe d'arrimage (10 Fig. 1); l'autre extrémité, après être passée dans la roulette de rappel (11) située au pied de l'arbre, va jusqu'à un appareil de traction (non  A rope (8) is then placed in the rollers (9) of the stem; one of its ends is hooked to the latching claw (10 Fig. 1); the other end, after passing through the return roller (11) located at the foot of the shaft, goes to a traction device (not

représenté) placé en dehors de la zone dangereuse.  shown) placed outside the danger zone.

A la première coupe, l'arrimage se fait au milieu du tronçon à couper (Fig. 2). Pour les autres, l'arrimage se fait en bout, dans l'axe du tronc (Fig. 1). Arrivé à l'un de ces stades, on bande le cordage à l'aide de l'appareil de traction et on place le pivot (12) qui équipe la tronçonneuse (13) dans l'alésage de la console (14) de l'élément support (6). La coupe peut alors se faire en toute sécurité. Le tronçon qui va être coupé étant maintenu par le cordage ne pourra pas pincer la châîne de la tronçonneuse pendant la coupe et ne tombera pas après celle-ci. La coupe terminée, à l'aide de la poignée de man_uvre (15), on fait pivoter l'ensemble élément support (6), potence (7) et tronçon afin que ce dernier se trouve en  At the first cut, stowage takes place in the middle of the section to be cut (Fig. 2). For the others, the stowage is done at the end, in the axis of the trunk (Fig. 1). At one of these stages, the cord is bandaged using the traction device and the pivot (12) which equips the chainsaw (13) is placed in the bore of the console (14) of the support element (6). The cutting can then be done safely. The section that will be cut being held by the rope will not be able to pinch the chain saw's chain during cutting and will not fall after it. When the cut is finished, using the operating handle (15), the support element (6), bracket (7) and section are pivoted so that the latter is in

La forme des demi-échelons (16) esttelle que les pieds de l'utilisateur qui reposent dessus se trouvent bloqués par la remontée des extrémités (22). De plus, cette forme "fermée" permet d'y accrocher de chaque côté un mousqueton, solidaire de la ceinture de sécurité, placée à la taille de l'opérateur. Elle lui laisse les mains libres tout en  The shape of the half-rungs (16) is such that the user's feet which rest on it are blocked by the raising of the ends (22). In addition, this "closed" shape allows to hang on each side a carabiner, secured to the seat belt, placed at the waist of the operator. She leaves her hands free while

lui assurant une parfaite tenue.ensuring a perfect hold.

Les demi-échelons (16) Figure 3 qui peuvent étres réalisés en fer rond sont fixés au tube de 1'élément (1) par soudures (28) de leurs brins (23) et (24) sur 1'extérieur du tube; le brin supérieur (23) vient en contact de celui-ci, le brin inférieur (24) plus long, pénètre et maintient ce tube et l'embo^ture (25) en les traversant ou bien sert de taquet d'orientation (26) s'encastrant dans l'encoche (27) faite à la base de l'embo^ture, I'ensemble garantissant ainsi un bon alignement des demiéchelons d'un élément à I'autre. L'épingle (17) placée à mi-hauteur de l'élément support, permet à la console (14) d'y étre bloquée, afin de pouvoir réaliser des demi-coupes lorsque le diamètre de l'arbre est supérieur à 3 5 cm; dans ce cas, on réalise deux coupes avec le méme positionnement de l'élément support. Cette méthode permet de couper des arbres d'un diamètre allant  The half rungs (16) Figure 3 which can be made of round iron are fixed to the tube of the element (1) by welding (28) of their strands (23) and (24) on the outside of the tube; the upper strand (23) comes into contact with the latter, the longer lower strand (24) penetrates and maintains this tube and the socket (25) by crossing them or else serves as an orientation cleat (26 ) fitting into the notch (27) made at the base of the socket, the assembly thus ensuring proper alignment of the half-steps from one element to the other. The pin (17) placed halfway up the support element allows the console (14) to be blocked there, so as to be able to make half cuts when the diameter of the shaft is greater than 3 5 cm; in this case, two cuts are made with the same positioning of the support element. This method allows trees with a diameter ranging from

jusqu'à 50 cm sans dépasser le poids fixé par les calculs.  up to 50 cm without exceeding the weight fixed by the calculations.

Les sous-ensembles griffes d'arrimage (10), griffes anti dévers (5) et griffe support roulette de rappel (18) sont fixés au tronc de l'arbre par une sangle bandée à 1'aide  The tie-down claws (10), anti-tilt claws (5) and claw support claw (18) sub-assemblies are fixed to the tree trunk by a strap bandaged using

Their purpose is to obtain a good attachment to the tree by penetrating into the trunk under the pressure of the straps. The chainsaw receives an equipment composed of a support (19) which allows it to be positioned horizontally on the console (14 ) and a chain protection casing (20). The casing (20) pivots on an axis fixed to the support (19), a return spring (21) 1ui covers the upper part of the chain as soon as it comes out of the notch
