The present invention relates to a mobile crane that comprises an undercarriage having a chassis and comprises a superstructure that is rotatable about a vertical axis relative to the undercarriage and has a telescopic boom at whose tip a boom head is arranged. The boom has holding means at one side for the support of a folding boom that can be releasably installed at the boom head. The boom laterally has a support and a holding element arranged between the support and the boom head. The folding boom is pivotable about a vertical axis of the holding element for the installation at the boom head, while it is supported on the support. In accordance with the present invention, a first securing device is arranged in the region of the support by means of which a movement of the folding boom deviating from a pivot movement about a vertical axis can be limited. The present invention further relates to a folding boom for the crane.

    本发明涉及一种移动式起重机,该移动式起重机包括具有行驶机构的下车以及可相对于下车绕竖直轴线转动的、具有可伸缩的吊臂的上车,在吊臂的顶端处布置有吊臂头部。吊臂在一侧上具有用于支承能够以可松开的方式装配在吊臂头部处的折叠臂的保持件。吊臂在侧向上具有支架和布置在支架和吊臂头部之间的保持元件。在折叠臂支撑在支架上时,折叠臂可绕保持元件的竖直轴线枢转以装配在吊臂头部处。根据本发明,在支架的区域中布置有第一防护装置,借助于第一防护装置可限制折叠臂的与绕竖直轴线的枢转运动不同的运动。此外,本发明涉及一种用于根据本发明的起重机的折叠臂。
