The utility model relates to the technical field of wire lifters, in particular to a wire lifter. The utility model provides a wire lifting device. The wire lifting device comprises a wire lifting device main body; a plurality of wire lifting hooks are uniformly arranged at the lower part of the wire lifter main body; wire lifting grooves are formed in the wire lifter main body and the wire lifting hooks; a floating block assembly is embedded in each wire lifting groove, the floating block assemblies are rotationally connected with the side walls of the wire lifting grooves, and rotating shafts of the floating blocks are perpendicular to the extending directions of the wire lifting grooves. The technical problem that the contact area between a wire and a wire lifter is small in the prior art is solved.
