Anti-tipping mechanism of crane

An anti-tipping mechanism of a crane comprises a hook-shaped device arranged on a crane cart end beam, the hook-shaped device comprises a vertical steel rod and a hook plate located at the bottom of the vertical steel rod, the top end of the vertical steel rod is fixed to the crane cart end beam through a pin, and the hook plate overhangs to the lower portion of a workshop rail bearing beam; and a safety space is formed between the hook plate and the lower edge of the workshop rail bearing beam. Compared with the prior art, the anti-falling device has the following beneficial effects that when the crane encounters an earthquake or violent impact, the crane cannot fall off from the cart track under the extreme condition, and the safety of the crane and a hoisted object is ensured. 一种起重机防倾翻机构，包括设置在起重机大车端梁上的钩型装置，钩型装置包括竖向钢杆以及位于竖向钢杆底部的钩板，其中，竖向钢杆的顶端通过销钉固定在起重机大车端梁上，钩板悬伸到车间承轨梁的下部；且钩板与车间承轨梁的下沿之间设有安全空间。与现有技术相比，本实用新型具有以下有益效果：保证起重机在遇到地震或猛烈冲击时，在这种极端情况下，起重机不会从大车轨道坠落，保证起重机自身及所吊物品的安全。
