The invention relates to a mobile crane comprising a movable chassis, an upper bracket mounted on the chassis for rotation about a vertical upper bracket axis of rotation and having a ballast means, a counterweight means, the counterweight device can be coupled to the ballast device and includes a counterweight base plate and at least one connecting element extending from the counterweight base plate for lifting and coupling the counterweight device to the ballast device. In the ballasting state, the distance of the counterweight device from the upper bracket rotation axis can be adjusted via at least one first arm of the ballasting device, and the first arm can pivot around the vertical rotation axis. According to the invention, the first arm in the ballasted state is connected to the counterweight base plate via a pivotable coupling element, which is pivotably mounted relative to the first arm and the counterweight base plate such that the first arm and the coupling element are pivoted at the same time. The counterweight substrate may be adjusted with linear movement radially relative to the upper bracket rotation axis.
本发明涉及一种移动式起重机,包括可移动的底架、安装在所述底架上以围绕竖直的上托架旋转轴线旋转并且具有压载装置的上托架、配重装置,配重装置能够联接至压载装置并且包括配重基板和从配重基板延伸以用于将配重装置提升并联接至压载装置的至少一个连接元件。在压载状态下,配重装置距上托架旋转轴线的距离可以经由压载装置的至少一个第一臂来调节,第一臂可以围绕竖直旋转轴线枢转。根据本发明,处于压载状态的第一臂经由可枢转的联接元件连接至配重基板,可枢转的联接元件相对于第一臂和配重基板可枢转地安装,使得通过同时枢转第一臂和联接元件,配重基板可以以相对于上托架旋转轴线径向的线性移动来调节。
