In side road emergences like tyre puncture or vehicle maintenance and repair, conventional carjacks used mechanical advantage to allow human power to raise the vehicle by manual force. This project showsmodification of current mechanical manual jack with the use of an electric DC motor in the screw in order to make loadlifting easier with the use of car battery.
