The invention relates to the technical field of bridge engineering construction, and discloses a pushing device, pushing equipment and a pushing system. The pushing device comprises a base, a jackingstructure movably arranged on the base, a first driving mechanism arranged on the base, and a second driving mechanism arranged on the base; the first driving mechanism is used for driving the jackingstructure to move on the base in the first direction; the second driving mechanism is used for driving the jacking structure to move on the base in the second direction; and the first direction and the second direction are perpendicular or diagonal, and the plane where the first direction and the second direction are jointly located is perpendicular to the pushing direction of the jacking structure. The pushing equipment comprises the pushing device and a control module. The pushing system comprises the pushing equipment and a linkage controller. In the bridge construction process, the pushing device can accurately adjust the position of a beam body again after the beam body is hoisted in place.
