The invention relates to a device with active lifting and automatic damping throwing. The device comprises a primary suspension, an upper connecting rod, a primary left rocking arm, a primary right rocking arm, a secondary left rocking arm, a secondary right rocking arm, a secondary suspension, a lower connecting rod, and an electrohydraulic actuator, wherein the electrohydraulic actuator is connected with the primary left rocking arm and the primary right rocking arm. A connecting rod mechanism is used for realizing the up-down movement of the secondary suspension by the stretching and retraction of a piston rod of the electrohydraulic actuator and under the restriction of the primary left rocking arm, the primary right rocking arm, the secondary left rocking arm, and the secondary rightrocking arm; by the restriction of the lower connecting rod to the secondary left rocking arm and the secondary right rocking arm, the secondary suspension is guaranteed to be always in a horizontal state; a damper on the electrohydraulic actuator can be used for limiting hydraulic pressure to drop too quickly, and can be used for performing damping deceleration when a load is thrown; and the connecting rod device is simple in structure, and is safe and reliable.
