The invention relates to the technical field of crane equipment, and discloses a lateral safety structure of a crane. The lateral safety structure comprises a lateral telescopic supporting leg, a frame and a lock catch, wherein the lateral telescopic supporting leg comprises a box body and a telescopic leg nested and connected in the box body; the frame is fixedly connected with the box body; thelock catch is arranged between the telescopic leg and the frame/box body and used for locking the telescopic leg and the frame; the lock catch has a locking position for connecting the telescopic legand the frame into a whole and an unlocking position for separating the telescopic leg and the frame from each other; the lock catch comprises a fixing piece and a hook; and the hook is rotatably connected to the fixing piece and rotates around the fixing piece to move from the locking position to the unlocking position. According to the lateral safety structure of the crane, the lateral telescopic supporting leg of the crane can be safely locked, and are prevented from stretching out in the running process so that accidents can be avoided.

    本发明涉及起重机设备技术领域,公开了一种起重机侧向安全结构,包括侧向伸缩支腿,包括箱体和嵌套连接在所述箱体内的伸缩腿;车架,与所述箱体固定连接;锁扣,设置在所述伸缩腿与所述车架/箱体之间,用于锁定所述伸缩腿与所述车架,所述锁扣具有将所述伸缩腿与所述车架连接为一体的锁定位置以及将所述伸缩腿与所述车架彼此分离的解锁位置;所述锁扣包括固定件、挂钩,所述挂钩转动连接在所述固定件上,所述挂钩围绕所述固定件转动从所述锁定位置运动到解锁位置。本发明用能够对起重机的侧向伸缩支腿进行安全锁定,避免起重机侧向伸缩支腿在行驶过程中伸出发生事故。
