Abstract

L'invention concerne un outil antidérapant avec lequel une charge sur un corps de véhicule peut être réduite et qui peut résister à une utilisation sur une longue période. Un outil antidérapant (1) selon un mode de réalisation de la présente invention est monté de manière amovible sur une chenille en caoutchouc (2) ayant, sur un corps de bande en caoutchouc en forme de boucle (2a), de multiples pattes de ruban en saillie (2b) avec des parties de ruban en retrait (2c) interposées entre elles. L'outil antidérapant (1) est pourvu d'une plaque centrale (5) divisée en trois sections et d'une paire de crochets latéraux (6). Des goujons (3) sont disposés sur un côté surface avant de la plaque centrale (5) de manière saillante, et une paire d'éléments écrous allongés (4) sont fixés au côté surface arrière de la plaque centrale (5). La plaque centrale (5) est conçue de sorte que, dans un état dans lequel les éléments écrous (4) sont logés dans les deux parties de ruban en retrait (2c) qui sont adjacentes aux pattes (2b) de la chenille en caoutchouc (2), des boulons (7) sont insérés dans des trous traversants (9b) formés dans une plaque de connexion (9) des crochets latéraux (6) et vissés dans des trous de vis (4a) des éléments écrous (4).
