The invention relates to the technical field of cranes, and provides a cart travel mechanism and a circular track crane. The number of the three-stage balance beam is one or two; when the number of the third-level balance beams is two, the two third-level balance beams are installed below the fourth-level balance beams through third-level saddles respectively. Walking units are respectively arranged at two ends of each group of three-stage balance beams; and the walking unit adopts a first walking structure, a second walking structure or a third walking structure. According to the invention, the mounting and dismounting convenience can be improved, the transformation of the circular track crane cart structure from an annular shape to a linear shape is realized, and the operation range of the circular track crane is widened.
本发明涉及起重机技术领域,提供一种大车运行机构及环轨起重机,所述大车运行机构包括:三级平衡梁;所述三级平衡梁的数量为一根或两根;当三级平衡梁的数量为两根时,两根三级平衡梁分别通过三级马鞍座安装在四级平衡梁下方;每组三级平衡梁的两端分别设置行走单元;所述行走单元采用第一行走结构、第二行走结构或第三行走结构。本发明能够提升安装和拆卸的便捷性,实现环轨起重机大车结构从环形到直线形的变换,提高环轨起重机的作业范围。
