The invention discloses a lifting hook device for a crane and the crane, the lifting hook device for the crane comprises a lifting hook body and an overturning hook connected with the end part of the lifting hook body, a lifting gap is formed between the overturning hook and the lifting hook body, and the lifting hook device for the crane further comprises a locking mechanism, the locking mechanism is arranged on the lifting hook body and can be connected with the turnover hook to seal the lifting gap or disconnected from the lifting hook body to expose the lifting gap. According to the hoisting device for the crane, when locking is needed, the locking mechanism can be connected with the overturning hook, so that the hoisting gap is closed, a hoisted object cannot be unhooked, when unhooking is needed, the locking mechanism is disconnected with the overturning hook, the hoisting gap is exposed, and due to the fact that the hoisted object has great gravity, the hoisting device can be locked. Therefore, the unhooking can be realized under the action of self gravity, and the unhooking can be quickly realized when the unhooking is needed.

    本发明公开一种起重机用吊钩装置及起重机,起重机用吊钩装置包括吊钩本体以及与所述吊钩本体的端部连接的翻转钩,所述翻转钩与所述吊钩本体之间形成吊装间隙,所述起重机用吊钩装置还包括锁定机构,所述锁定机构设置在所述吊钩本体上并能够与所述翻转钩连接以封闭所述吊装间隙或与所述吊钩本体脱离连接以露出所述吊装间隙。本发明提供的起重机用吊装装置能够在需要锁定时,可通过锁定机构与翻转钩连接,从而将吊装间隙封闭,令吊装物无法脱钩,而在要脱钩时,锁定机构与翻转钩脱离连接,将吊装间隙露出,而由于吊装物本身具有极大的重力,从而能够在自身重力的作用下脱钩,使其在需要脱钩时能够迅速脱钩。
