Disclosed herein is an automatic folding fork device for forklift trucks. The folding fork device is operated so that forks are rotated upwards and folded by the rotation of a hydraulic motor when a driver driving in a forklift truck easily manipulates a lever or switch, thus allowing the forklift truck to move safely, with the forks in a folded state. Further, this invention is constructed so that external threaded parts, having threads formed in opposite directions, are provided on both sides of the outer circumferential surface of a shaft, and coupling pipes having internal threaded parts corresponding to the external threaded parts are provided, thus allowing an interval between the forks mounted to the coupling pipes to be adjusted, according to the rotating direction of the hydraulic motor.

Dispositif de fourche repliable automatique pour chariots élévateurs à fourche. Le dispositif de fourche repliable est actionné de manière à tourner les fourches vers le haut et à les replier par la rotation d'un moteur hydraulique lorsqu'un chauffeur conduisant un chariot élévateur à fourche manipule aisément un levier ou un interrupteur, permettant ainsi au chariot élévateur à fourche de se déplacer en toute sécurité avec ses fourches repliées. De plus, cette invention est fabriquée de sorte que des pièces filetées externes, pourvues d'un filetage dans des sens opposés, soient fournies de chaque côté de la surface circonférentielle extérieure d'un arbre et que des tuyaux de raccord pourvus de pièces filetées internes correspondant aux pièces filetées externes soient fournies, permettant ainsi d'ajuster un intervalle entre les fourches montées sur les raccords, selon le sens de rotation du moteur hydraulique.
