The invention provides a lifting hook, a lifting appliance and a lifting device. The lifting hook can be connected with a lifting point of a to-be-lifted part and comprises a mounting bracket, a firstlifting claw, a second lifting claw and a sliding driving part; a guide sliding part is arranged on the mounting bracket; the first lifting claw and the second lifting claw are connected to the samelifting point, are matched with each other and are glidingly arranged on the guide sliding part; and the sliding driving part is arranged on the mounting bracket, is in driving connection with the first lifting claw and the second lifting claw, and is used for driving the first lifting claw and the second lifting claw to linearly slide on the guide sliding part in a reciprocating manner. Accordingto the lifting hook, the lifting appliance and the lifting device, when the two lifting claws of the lifting hook are in the open state, the allowable space with the relatively-large gap is formed between the two lifting claws, so that the lifting hook is applicable to lifting lugs of laminated slabs with the relatively-large size, and the applicability is relatively high; besides, the lifting claws of the lifting hook are not prone to unhooking when the laminated slabs are lifted, and the practicability is relatively high.

    本申请提供一种吊钩、吊具及起吊装置,吊钩可与待吊件的吊点连接,包括:安装支架,所述安装支架上设置有导滑件;连接于同一所述吊点且彼此相配合的第一吊爪及第二吊爪,所述第一吊爪及所述第二吊爪滑动设置于所述导滑件上;滑动驱动机件,所述滑动驱动机件设置于所述安装支架上,并与所述第一吊爪及所述第二吊爪驱动连接,用于驱动所述第一吊爪及所述第二吊爪在所述导滑件上直线往复滑动。本申请的吊钩、吊具及起吊装置,吊钩的两个吊爪处于打开状态时,两个吊爪之间形成间隙相对较大的容许空间,从而可以适用于尺寸较大的叠合板的吊耳,适用性较强,并且,该吊钩的吊爪也不容易在叠合板起吊时脱钩,实用性也较强。
