The invention belongs to the technical field of hollow slab installation, particularly relates to a vertical hoisting tool for hollow slabs, and aims to solve the problem of blank of vertical hoisting tools for hollow slabs in the prior art. The vertical hoisting tool for hollow slabs comprises a first hoisting assembly, a second hoisting assembly, a third hoisting assembly and a hoisting rod; the first hoisting assembly comprises a hoisting ring, the second hoisting assembly comprises a separating ring, the third hoisting assembly comprises a second tubular structure and an expansion assembly which are coaxially and sequentially hinged, and in the working state, the elastic element is arranged outside the first structure part in a sleeving mode and limited through the limiting part; the lifting rod sequentially penetrates through the third lifting assembly, the second lifting assembly and the first lifting assembly and is fixed to the first lifting assembly through a detachable connecting piece, and the first lifting assembly is lifted to drive the lifting rod to move so that the end, close to the expansion end of the lifting rod, of the expansion assembly can be passively expanded in the radial direction. The invention provides a reliable hoisting tool for vertical use and vertical hoisting of the hollow slab.
