The invention relates to the technical field of bridge construction, and provides a hoisting method and a hoisting system of a cable crane, and the hoisting method of the cable crane comprises the following steps: two tackle parts respectively swing and move two walking mechanisms to a position above a main cable by adopting a hoisting point conversion mode, and the two walking mechanisms are connected to a set position of the main cable; the two main beam sections are swung to the position above the walking mechanism through the two tackle parts in a lifting point conversion mode, and the two main beam sections are connected to the walking mechanism; the middle truss girder is lifted to the position between the two main beam sections through cooperation of the two tackle parts, and the two ends of the middle truss girder are connected to the main beam sections correspondingly; the two cable loading winches are hoisted to the corresponding walking mechanisms respectively, and the two cable loading winches are connected to the corresponding walking mechanisms respectively; the method can be suitable for designing the portal frame which is small in initial structure and is not provided with a sliding system, and the application range and universality of the hoisting system are improved.
本发明涉及桥梁施工技术领域,并提供一种缆载起重机的吊装方法及吊装系统,该缆载起重机的吊装方法包括:通过两个所述滑车部分别将两个走行机构采用吊点转换方式荡移至主缆的上方,将两个走行机构连接至所述主缆的设定位置;通过两个滑车部分别将两个主梁分段采用吊点转换方式荡移至走行机构的上方,将两个主梁分段分别连接于走行机构;通过两个滑车部配合,将中间桁架梁起吊至两个主梁分段之间处,将中间桁架梁的两端分别连接于主梁分段;将两个缆载卷扬机分别起吊至对应的走行机构上,将两个缆载卷扬机分别连接于对应的所述走行机构;本发明能够适用于设计初期结构较小且没有滑移系统的门架,增大了吊装系统的适用范围和通用性。
