The invention relates to a crane, in particular a mobile truss mast crane, comprising a superstructure, a boom which is hinged to the superstructure in a liftable manner, and a traction frame which is hinged to the superstructure in a liftable manner. The traction frame can be connected to the boom by means of a traction structure and to the superstructure by means of an actively adjustable traction strand, wherein the traction strand comprises a traction rope which is mounted on the winch in a winding and unwinding manner. According to the invention, the crane comprises a length-variable traction element, by means of which the traction frame can be connected in an articulated manner to the boom, and the traction element is designed to exert a traction force on the traction frame in the direction of the boom. The invention also relates to a method for bringing the crane according to the invention into a traction working position.
本发明涉及一种起重机,特别是移动式桁架桅杆起重机,具有上部结构、可升降地铰接在上部结构上的起重臂和可升降地铰接在上部结构上的牵拉框架。牵拉框架能够通过牵拉结构与起重臂连接并且通过可主动调节的牵拉绞合部与上部结构连接,其中牵拉绞合部包括可缠绕和退卷地安装在绞盘上的牵拉绳。根据本发明,起重机包括长度可变的牵引元件,牵拉框架通过牵引元件与起重臂能够铰接地连接,并且牵引元件被设计成,沿起重臂的方向在牵拉框架上施加牵引力。本发明还涉及一种用于将根据本发明的起重机带入牵拉工作位置的方法。
