Abstract
An apparatus, program product, and related methods for gravity stabilizing a suspended load are provided. The apparatus includes an center of gravity stabilized automated adjusting load bar in communication with a mobile cart which allows an operator to enable automated stabilization of a load. The adjusting load bar includes redundant first and second control and drive systems. A third control system can both monitor sensed data and the movement commands of first and second control systems, and can monitor the resulting physical movements. If a movement command and the resulting movement does not match or if there is an out of tolerance mismatch between movement commands of the first and the second control systems, the third control system can automatically detect this condition and shift into an emergency stop condition.
