The invention provides an auxiliary lifting device for escalators. The auxiliary lifting device for escalators is used for lifting the escalators. The auxiliary lifting device for the escalators comprises a transverse rod (2), wherein upper lifting rings (1) are fixedly arranged at the two ends of the transverse rod (2) respectively, lower lifting rings (3) are further fixedly arranged at the two ends of the transverse rod (2) respectively, and lifting holes are formed in the upper lifting rings (2) and the lower lifting rings (3) respectively; each lower lifting ring (3) is detachably connected with a shackle (4), and each shackle (4) is detachably connected with a lifting plate (5); and the lifting plates (5) at the two ends of the transverse rod (3) are attached to and detachably connected with the two sides of a truss of an escalator respectively. Compared with the prior art, the auxiliary lifting device for escalators takes the advantage of the framing effect formed by the transverse rod and the truss of the escalator to effectively resist lateral component force of lifting tension, and lateral stress deformation of the escalator is reduced; and in addition, the auxiliary lifting device for the escalators can be recycled, and the efficiency of lifting of the escalators is greatly improved.
