The invention discloses a frame type lifting arm for a pantograph. The frame type lifting arm mainly solves the technical problems that the existing maintenance cost of external power supply of rail transit vehicles is high and an overhead line is easily broken when breakdowns occur. The frame type lifting arm is technically characterized in that the pantograph comprises a base assembly (5), a supporting arm, a lifting arm, a lifting power device (4), a spring assembly (8) and a pantograph bow assembly (10), insulators B (3) are arranged under the base assembly (5), and the supporting arm and the lifting arm are matched to form a linked movable crank arm frame structure. The frame type lifting arm can be widely applied to pantographs of various rail and non-rail transit vehicles and electric drive vehicles such as haulage trucks.
