A lifting machine base assembly for use in a machine tool includes a machine base and a lateral wheel set. The lateral wheel set includes two lateral wheel frames respectively pivotally connected to two opposite sidewalls of the machine base, and a wheel shaft rotatably inserted through the machine base and eccentrically connected between the lateral wheel frames. A driving member is fastened to one end of the wheel shaft and operable to raise and lower the lateral wheel frames relative to the machine base and to further force the lateral wheels into contact with the floor to lift the machine base partially or wholly from the floor, allowing the operator to conveniently move the machine tool to a desired position by rotation of the lateral wheels. |
