History
This fully transistorized Centrifuge Machine was created by Stark in order to build up the greatest gravity force ever harnessed. He even managed to trap all that cataclysmic energy in a transistorized porta-pack device, which used against the Crusher, causing his gravity to exponentially increase.[1]
Having freed himself from the center of the Earth, the Crusher attacked the plant once again to use the device against Iron Man, but he couldn't operate the device, which exploded in his hands.[2]
