The invention relates to a tower crane, and discloses a boom and tower body connecting system of a tower crane and the tower crane, the boom and tower body connecting system of the tower crane comprises a tower body and a boom, the top of the tower body is provided with a mounting seat, the mounting seat comprises a balance arm side main beam and a cargo boom side main beam, the balance arm side main beam is hinged to a balance arm side mounting hole of the arm frame, and the cargo boom side main beam is hinged to a cargo boom side mounting hole of the arm frame in a quick-release mode through a cargo boom side pin shaft. And in the working process, the hinging between the cargo boom side main beam and the cargo boom side mounting hole of the boom frame can be realized or released. The method can be suitable for the special working condition that the cantilever crane inclines towards the balance arm side to fall off the balance weight so as to balance the bending moment, the impact of sudden unloading on the tower crane structure is reduced, and the safety performance of the tower crane is improved.

    本发明涉及塔式起重机,公开了一种塔式起重机的臂架与塔身连接系统及塔式起重机,该塔式起重机的臂架与塔身连接系统包括塔身和臂架,所述塔身顶部设置有安装座,所述安装座包括平衡臂侧主梁和起重臂侧主梁,所述平衡臂侧主梁与所述臂架的平衡臂侧安装孔铰接,所述起重臂侧主梁与所述臂架的起重臂侧安装孔之间通过起重臂侧销轴形成快拆式铰接,以在工作过程中能够实现或解除所述起重臂侧主梁与所述臂架的起重臂侧安装孔之间的铰接。能够适用于臂架向平衡臂侧倾斜来脱落平衡重以平衡弯矩的特殊工况,减小突然卸载对塔机结构的冲击,增加塔机的安全性能。
