The invention relates to the technical field of cranes, in particular to a crane main beam and a crane using the same, which can adjust the horizontal state of the main beam, assist a crane carriage in starting and moving and effectively reduce starting current and running current, and are good in practicability and high in safety. Comprising a hoisting trolley, and a winding machine and a walking track wheel set are installed on the hoisting trolley; the crane further comprises two bearing frames, a movable beam, two upper limiting connecting structures, two lower limiting connecting structures and an angle adjusting mechanism, the upper limiting connecting structures are arranged on the two bearing frames, the crane carriage walks on the movable beam, the movable beam is provided with the lower limiting connecting structures matched with the two upper limiting connecting structures, and the angle adjusting mechanism is arranged on the lower limiting connecting structures. The lower limiting connecting structure and the upper limiting connecting structure of the movable beam are movably connected, the angle adjusting mechanisms are connected with the two bearing frames and the left end and the right end of the movable beam respectively, and the angle adjusting mechanisms drive the movable beam to incline by a certain angle, so that the crane carriage can slide in the designated direction along the movable beam under the action of gravity.

    本发明涉及起重机的技术领域,特别是涉及一种起重机主梁与使用该主梁的起重机,其能够调节主梁的水平状态,辅助起重小车启动和移动,有效降低启动电流和运行电流,实用性好安全性高;包括起重小车,起重小车上安装有卷收机和行走轨道轮组;还包括两个承载架、可动梁、两个上限位连接结构、两个下限位连接结构和调角机构,两个承载架上均设置有上限位连接结构,起重小车在可动梁上行走,可动梁设置有与两个上限位连接结构匹配的下限位连接结构,可动梁的下限位连接结构与上限位连接结构活动连接,调角机构分别连接两个承载架与可动梁的左右两端,调角机构带动可动梁倾斜一定角度,使得起重小车能够在重力作用下沿着可动梁向指定方向滑行。
