The invention relates to the field of hoisting machinery, and discloses a crane and an anti-overturning control method thereof.The crane comprises a hanging assembly (4) used for being connected with a hoisted load and balance weight modules (3) oppositely arranged at intervals relative to the hanging assembly, and each balance weight module (3) comprises a self-discharging balance weight (31) locked at an installation position through a self-discharging locking mechanism (5); the self-discharging locking mechanism (5) is arranged to release at least part of the self-discharging balance weight (31) under the condition that the hanging assembly (4) is unloaded suddenly, so that at least part of the self-discharging balance weight falls off from the installation position. According to the crane, at least part of the self-discharging balance weight can be released under the condition of sudden unloading such as rope breaking, so that the lifting motion caused by the violent change of the instantaneous load borne by the suspension arm is inhibited, the bending moment impact on the mounting foundation where the crane is located is reduced or avoided, and the risk of overturning accidents is effectively reduced; and the design requirements of ultra-large cranes can be met.
本发明涉及起重机械领域,公开了一种起重机及其防倾覆控制方法,所述起重机包括用于连接被吊运的负载的吊挂组件(4)和相对该吊挂组件间隔相对布置的平衡重模块(3),该平衡重模块(3)包括由自卸锁止机构(5)锁止于安装位置的自卸平衡重(31),所述自卸锁止机构(5)设置为在吊挂组件(4)突发卸载的情况下释放至少部分自卸平衡重(31),以使得至少部分所述自卸平衡重从安装位置脱落。该起重机可以在发生断绳等突发卸载的情况下通过释放至少部分自卸平衡重而抑制吊臂因承受的瞬时载荷剧烈变化导致的上扬运动,从而减小或避免对其所在的安装基础的弯矩冲击,有效降低了发生倾覆事故的风险,并有利于满足超大型起重机的设计要求。
