Abstract

Dispositif de sécurité contre les surcharges, adaptable à une barre d'attelage d'un dispositif de levage de tracteur. La barre d'attelage est munie d'un dispositif de sécurité contre les surcharges, caractérisé en ce que ladite barre est constituée de deux parties, formant deux moitiés d'accouplement, rigidement reliées entre elles en fonctionnement normal par un dispositif de verrouillage et en ce que, lors d'une surcharge, les deux parties sont déverrouillées et peuvent se déplacer l'une vers l'autre en provoquant le basculement vers l'avant de l'organe de travail attelé. Application aux bielles supérieures de dispositifs d'attelage à un tracteur.Safety device against overloads, adaptable to a drawbar of a tractor lifting device. The drawbar is provided with a safety device against overloads, characterized in that said bar consists of two parts, forming two coupling halves, rigidly connected to each other in normal operation by a locking device and in that, during an overload, the two parts are unlocked and can move towards one another causing the hitched working member to tilt forward. Application to upper connecting rods for coupling devices to a tractor.
