Abstract

L'invention concerne un dispositif de suspension de charge (2) comprenant un système de suspension de charge du type moufle à chaîne équipé d'un élément rotatif (21) sur lequel un câble de soutien (31) est tendu dans une direction différente de la direction de traction d'une charge, destinée à être élevée et abaissée par un système de suspension de charge (2), et soutenue rotative sur le câble de soutien (31). Il existe en outre un système d'entraînement (22) pour l'élément rotatif. On peut ainsi installer et transporter facilement le dispositif de suspension de charge, et manipuler celui-ci plus aisément. Le dispositif de suspension de charge classique comprenant un système de suspension de charge du type moufle à chaîne, aux fins de levage, et un élément de soutien pour ce système de suspension de charge, nécessite un châssis de grande dimension, avec un dispositif de transfert pour transférer la charge qui est suspendue via le système de suspension vers un autre emplacement : il en résulte pour toute l'installation une taille et un poids accrus, c'est-à-dire une augmentation des contraintes de transfert sur le dispositif de suspension de charge lui-même, ce qui nuit à la commodité d'un tel dispositif.
