The invention discloses a lifting mechanism with a high compression ratio and an unbalance loading function. The lifting mechanism comprises a bottom plate, a top plate and a lifting mechanism arranged between the bottom plate and the top plate, the lifting mechanism comprises a shear fork assembly, a rigid chain assembly and a first driving mechanism, the bottom of the shear fork assembly is installed on the bottom plate, the top of the shear fork assembly is installed on the top plate, the rigid chain assembly is installed on the bottom plate, the top of the rigid chain assembly is connected with the bottom face of the top plate, the first driving mechanism is used for driving the rigid chain assembly to ascend and descend, a lifting adjusting platform capable of moving front and back is arranged on the top of the top plate, and an offset telescopic arm capable of moving left and right is arranged on the lifting adjusting platform. According to the lifting mechanism, the requirement for rapidly disassembling and assembling under-vehicle parts of a motor train unit in the rail bridge operation mode can be met, and meanwhile the operation requirement that the highest workpiece can be safely disassembled from the side face of a rail bridge and does not collide with a train body in the retracting state is met.
