The invention discloses a multi-dimensional comprehensive lifting device for a transformer assembly. A left double shear fork lifting device and a right double shear fork lifting device which are driven by a left hydraulic cylinder and a right hydraulic cylinder are mounted on a left base and a right base respectively, a cross beam is mounted at the tops of the left double shear fork lifting device and the right double shear fork lifting device, and a lifting hook for lifting a transformer lifting bell jar is mounted on the cross beam; a displacement sensor which detects whether the lifting heights of the left double shear fork lifting device and the right double shear fork lifting device are constant is mounted on the cross beam; the displacement sensor is connected with a control system; the cross beam comprises left and right groups of longitudinal rods as well as a front horizontal rod and a back horizontal rod, the left and right groups of longitudinal rods are composed of two longitudinal rods respectively, and each longitudinal rod is fixedly connected with the top of a shear fork lifting part of the double shear fork lifting device; the four mutually parallel horizontal rods are fixedly connected with the left and right groups of longitudinal rods; the cross beam is formed by I-shaped steel. The transformer lifting device adopts a double shear fork type portal structure, the maximum lifting height can reach 8 meters, and the maximum lifting weight can reach 10 tons.
