The invention discloses a horizontal lifting appliance for a concrete segment. The horizontal lifting appliance comprises a cross beam, an upper lifting lug, lower lifting lugs, lifting rings, liftingchains and lifting fixtures, wherein a plurality of clamping grooves matched with the lifting rings are formed in the lower lifting lugs, and at least two lifting chains are connected to the lower ends of the lifting rings; the lifting fixtures are connected to the lower ends of the lifting chains; each lifting fixture comprises a fixture seat and an arc-shaped bolt detachably connected with thefixture seat; and the lower end of each fixture seat is an open end, and each fixture seat comprises a horizontal part and a vertical part and an inclined part arranged on two opposite sides of the horizontal part. The horizontal lifting appliance has the beneficial effects as follows: the horizontal lifting appliance adopts the cross beam and the lifting chains as load-bearing carriers, and is high in safety coefficient and long in service life; during field lifting, lifting operation can be performed as long as the fixture seats are placed in bolt hole positions of the to-be-lifted segment and the arc-shaped bolts are inserted in fixture seat through holes to be connected with the segment, the field operation is simple, rapid and convenient, and the segment lifting efficiency can be remarkably improved.
