Designers Jin Yuanbiao, Qui Meng, Lu Xiao and Tang Gang have created a mini crane that can be controlled at the palm of your hands.  By pressing one of the 3 available buttons, Bumblebee can transform from a vacuum like canister to a non industrial sized crane.  Bumblebee’s creator claims it can handle heavy weights.  However, I have my reserves that this crane can function as an engine lift.  You know for those emergency engine swaps.  On a side note, I’d really like to see a clip of this crane in action.
