The invention relates to the technical field of installation of reinforcing meshes, in particular to a multipoint flexible lifting device. The multipoint flexible lifting device comprises a plurality of lifting hooks, elastic devices and a lifting frame. The lifting hooks are arranged on the lifting frame. Each elastic device is arranged between the lifting frame and the corresponding lifting hook or on each lifting hook and used for buffering the action force between the lifting hook and a reinforcing mesh, and therefore the lifting hooks evenly bear the weight of the reinforcing mesh. According to the multipoint flexible lifting device, the elastic devices are arranged between the lifting hooks and the lifting frame or on the lifting hooks so that the lifting hooks can evenly bear the weight of the lifted mesh and buffer the action force between the lifting hooks and the reinforcing mesh at the same time. When the reinforcing mesh is lifted, the elastic devices elastically deform under the effect of gravity of the reinforcing mesh, so that the lifting hook are adaptive to the shape and position errors of the reinforcing mesh, all lifting points on the reinforcing mesh evenly bear force in the whole lifting and installing process, and the reinforcing mesh is prevented from deforming due to uneven stress.
