Abstract

La présente invention a pour objet un appareil de levage comportant deux colonnes verticales écartées l'une de l'autre et par rapport à chacune desquelles est monté coulissant verticalement un bras ou une fourche de levage, chaque colonne contenant une via rotative, sensiblement fixe en translation, reliée à un moteur d'entraînement commun aux deux via et en prise avec un écrou ne pouvant tourner, solidaire du bras ou de la fourche de levage. Selon l'invention, chacune des via 18 est reliée au moteur d'entraînement par des accouplements élastiques ainsi qu'à une dynamo tachymétrique 40; les deux dynamos 40 sont reliées à un comparateur 41 propre à arrêter le moteur d'entraînement 32 lorsque la différence de vitesses des deux via 18 atteint une valeur ornée.
