The present invention relates to a crane system (2) comprising a trolley (7) to support a load and movable about a horizontal direction to provide movement of the load in a horizontal direction accordingly and a carrying member (10) supported by the trolley (7) and configured to carrying the load in use. A sensor (22,24) to measures the angle of the carrying member (10) relative to the trolley (7) and a controller (20) is configured to provide a dynamic model of the trolley (7) to determine an estimated angle of the carrying member (10) during movement of the trolley (7). The controller (20) is configured to compare to the estimated angle and the measured angle and control horizontal movement of trolley (7) in accordance with said comparison.

    La présente invention concerne un système de grue (2) comprenant un chariot (7) pour supporter une charge et mobile autour d'une direction horizontale afin de fournir un mouvement de la charge dans une direction horizontale en conséquence et un élément de transport (10) supporté par le chariot (7) et configuré pour transporter la charge lors de l'utilisation. Un capteur (22, 24) pour mesurer l'angle de l'élément de transport (10) par rapport au chariot (7) et un dispositif de commande (20) est configuré pour fournir un modèle dynamique du chariot (7) afin de déterminer un angle estimé de l'élément de transport (10) pendant le mouvement du chariot (7). Le dispositif de commande (20) est conçu pour comparer l'angle estimé et l'angle mesuré et commander le mouvement horizontal du chariot (7) en fonction de ladite comparaison.
