Abstract

La présente invention concerne un perfectionnement aux grues sur plate-forme mobile. La grue comporte une flèche 9 et une contre-flèche 10 montées sur un pivot 5 et solidaires à la rotation, un chariot 13 mobile le long de la flèche 9 et portant des poulies 17 sur lesquelles passe le câble 16 de suspension du crochet 14, câble 16 dont une extrémité est enroulée sur le tambour 18 d'un treuil 19 et un contre-poids 34 monté sur la contre-flèche 10, la position du contre-poids 34 sur la contre-flèche 10 étant variable et sa distance au pivot 5 étant asservie à un dispositif de calcul 42 calculant le produit instantané de la charge par la distance de la charge au pivot de manière à sensiblement annuler le couple de renversement sur le pivot. Cette grue est utilisée pour le transport de charges notamment sur voies ferrées.
