ABSTRACT:
In general, an electrically operated car jack is described. A typical embodiment includes a base frame or housing that is adapted to be placed on the ground underneath the automobile to be lifted. The housing includes motors connected to drive arms connected to a load bridge and plate. The bridge is typically mounted within the drive arms by rods located within slots on the arms enabling the bridge to move upward and downward while being retained within the drive arms. Typically, the motors are operated by the car's battery. The drive arms typically include drive wheels that rotate oppositely and are coupled together by a coupler in an X-configuration that assures the coupler moves uniformly. The motors drive the arms, lifting and lowering the load bridge which lifts and lowers the automobile. The jack can be operated by remote control.
