Crane, in particular mobile crane with a narrow track and enlarged supporting base. Cranes with a moving gear with rubber tyres are generally equipped with stays. Loads can generally be lifted only when the crane stands on the stays. The forces are not generally uniformed distributed among the stays in operation, creating a torsional moment in the central part and also in the tracks. The invention addresses the problem of providing a crane, in particular a mobile crane on a narrow tracked moving gear, with stays arranged in such a way that an enlarged supporting base is achieved. The present crane comprises a truck, a superstructure and a jib arranged thereon, the superstructure being joined to the truck by a revolving connection and multiple stays being provided on the crane in order to increase the supporting base. The orientation of the stays is fixed in such a way that they form an angle of 90~ with each other, two stays being oriented in the longitudinal direction of the truck and two transversely thereto. This arrangement creates a direct power flow, and no avoidable moments arise.
La présente invention concerne une grue comprenant un châssis, une superstructure (12), ainsi qu'une flèche (13) montée sur la superstructure. La superstructure est reliée au châssis via une liaison rotative (15) et la grue comprend quatre appuis (8, 9, 10, 11) qui servent à rehausser la base d'appui. L'orientation des appuis est fixée de sorte qu'ils forment entre eux respectivement un angle de 90°, deux des appuis (8, 9) étant orientés en sens longitudinal du châssis et deux appuis (10, 11) étant orientés perpendiculairement au châssis. Dans un mode de réalisation alternatif, quatre bras de support sont placés de manière centrale par rapport au centre de rotation. Au moins un des appuis (16, 20) s'appuie en au moins deux points et la ligne qui relie ces points (19) forme un bord de basculement.
