The invention discloses a multi-size split type combined lifting appliance comprising a bearing disc and a reducing sliding block. A sliding rail, extending towards the center of the bearing disc, is vertically fixed on the upper end face of the bearing disc, and a strip-type hole in a direction same as the extending direction of the sliding rail is formed in the sliding rail; the reducing sliding block comprises a lifting block, and a lock bolt component assembled with the strip-type hole of the sliding block; one end on which a threaded stud is arranged, of the lock bolt component is fixed at the side wall of the lifting block by welding, while the other end of the lock bolt component stretches out the strip-type hole of the sliding rail and is located in a manner of being locked by a nut; and the upper end face of the lifting block is provided with a hanging ring. According to the lifting appliance adopting the technical scheme, the bearing disc mainly bears the gravity of goods, moreover, as the lifting block is arranged, the lifting block can be regulated to firstly clamp and preload the lifted goods, the lifting block is located through the bolt component, and the hanging ring is lifted directly through a steel wire rope so as to pull the lifting block, as a result, the lifting block is facilitated to inclining towards the center of the bearing disc and further clamping the lifted goods, and safety of lifting is guaranteed.
