The invention relates to a crane main beam and a crane using the main beam, the crane main beam comprises an I-shaped frame, an end beam, a telescopic shaft, a connecting plate, a positioning screw, an inclined plane, a main beam plane and a main beam, the end beam is fixed above the I-shaped frame through welding, the telescopic shaft is sleeved above the end beam, and the connecting plate is connected with the inclined plane. And the main beam is fixed on the telescopic shaft through a positioning screw. According to the crane main beam, the relative height between the main beam and the end beam can be adjusted, so that the operation height of the crane is changed, the application range of the crane is expanded, a gradient is arranged at the joint of the end beam and the main beam of the crane, smooth transition is achieved, and the overall height of a common crane is low under the condition that the same running tonnage is ensured; the plant height is correspondingly reduced, and the cost is reduced; the gradient between the end beam and the main beam enables the trolley to be in smooth transition, the structural strength is guaranteed, the structure is simple, operation is stable, cost is saved, the application range is wide, and the bearing capacity is high.

    本发明涉及一种起重机主梁及使用该主梁的起重机,起重起重机主梁包括工字架、端梁、伸缩轴、连接板、定位螺钉、斜面、主梁平面和主梁,所述端梁通过焊接固定在工字架的上方,所述伸缩轴套在端梁的上方,所述主梁通过定位螺钉固定在伸缩轴上。该起重机主梁能调整主梁和端梁间的相对高度,从而改变起重机的作业高度,扩大了起重机的应用范围将起重机的端梁与主梁的连接处设置了一坡度,使之平稳过渡,保证在行车吨位相同的情况下使普通起重机的总体高度低,厂房高度相应降低,降低成本;端梁与主梁之间的坡度使小车平稳过渡,保证了结构强度结构简单,运行稳定、节约成本,适用范围广,承载能力强。
