The invention relates to the technical field of prefabricated part lifting appliances, in particular to a concrete prefabricated part lifting appliance which comprises a top plate, four transverse sleeves fixed to the positions, on the two sides, of the upper surface of the top plate, a lifting ring is fixed to the position, in the center, of the upper surface of the top plate, and the four transverse sleeves are fixed to the positions, on the two sides, of the upper surface of the top plate. Sliding rods are slidably inserted into the inner sides of the four transverse sleeves correspondingly, and side vertical rods are fixed to one ends of the four sliding rods correspondingly. Through the four suspension mechanisms and the two pressurization mechanisms, when the lifting appliance drives the prefabricated slab to move downwards to be placed on the sole timber, the prefabricated slab can be suspended firstly, and when the prefabricated slab makes contact with the sole timber, the gravity of the prefabricated slab can be slowly transferred to the sole timber, so that the impact strength between the prefabricated slab and the sole timber can be greatly reduced, and the construction efficiency is improved. The situation that the lifting appliance and the prefabricated slab descend too fast, so that the prefabricated slab and the sole timber collide strongly, and the prefabricated slab is damaged is avoided.

    本发明涉及预制件吊具技术领域,尤其是涉及一种混凝土预制件吊具,包括顶板,所述顶板的一端安装有控制器,且顶板的上表面位于中心位置处固定有吊环,还包括:固定在顶板上表面位于两侧位置处的四个横向套筒,四个所述横向套筒的内侧均滑动插设有滑杆,四个所述滑杆的一端均固定有侧竖杆。本发明通过四个悬浮机构和两个增压机构,在吊具带动预制板下移放置在垫木上时,可以首先使预制板悬浮,当预制板与垫木接触时,可以使预制板的重力缓慢地向垫木上转移,从而可以大幅减小预制板与垫木之间的冲击力度,防止吊具和预制板下降速度过快导致预制板与垫木之间产生强大的撞击,导致预制板损坏。
