The invention relates to a lifting appliance. The lifting appliance comprises a first lifting hook, and the first lifting hook comprises a fixed positioning pin, a movable positioning pin, a fixed block and an elastic piece. When a carrying frame is hoisted, by moving the movable positioning pin, a fixed space is formed between the second pair of top parts of the movable positioning pin and the first pair of top parts of the fixed positioning pin, at the moment, the elastic piece is in a compressed state, the hoisting holes of the carrying frame can enter the fixed space, the first pair of top parts and the second pair of top parts can stretch into the hoisting holes correspondingly, and then the movable positioning pin is released, and the elastic force applied by the elastic piece enables the first pair of top parts and the second pair of top parts to tightly abut against the bottoms of the lifting holes. Due to the action of the elastic piece, the first pair of top parts and the second pair of top parts can tightly abut against the bottoms of the lifting holes, and the first lifting hook is prevented from moving relative to the carrying frame; and meanwhile, whether the first lifting hook clamps the carrying frame or not can be judged by directly observing whether the elastic piece is in a compressed state or not.

    本发明涉及一种上述吊具,包括第一吊钩,其包括固定定位销、活动定位销、固定块以及弹性件。在吊装运载架时,通过移动活动定位销,使得活动定位销的第二对顶部与固定定位销的第一对顶部之间形成固定空间,此时弹性件为压缩状态,运载架的吊孔能够进入到固定空间内,第一对顶部和第二对顶部能够分别伸入到吊孔内,然后释放活动定位销,弹性件施加的弹力使得第一对顶部和第二对顶部能够紧密地与吊孔的底部抵接。由于弹性件的作用,使得第一对顶部和第二对顶部能够紧密地与吊孔的底部抵接,防止了第一吊钩相对运载架的移动。同时,通过直接观察弹性件是否为压缩状态,即可判断第一吊钩是否夹紧运载架。
