A ramp employee describes his efforts to address an unsafe condition that occurs while towing crj-700 aircraft using super tugs that have an automated electric-hydraulic nose gear cradle system. Crj-700 nose gears have shifted sideways inside the cradle during turning motions causing nose tires to be cut after striking the cradle hydraulic unit. Other times the nose gear will slam forward into the hydraulic unit.

Narrative:
We were dispatched to move a crj-700 aircraft. As we were going the taxiway; [over] the first hump; I looked back and saw that the plane's front main shifted to the right while in the cradle. This is not the first time this happened. I reported a few months back [that the] same thing happened with other crj-700 aircraft; where the tires were cut. Our ground support equipment department tell us there's nothing they can do. My fear that one day as we are towing other crj-700s that it will disconnect from the super tugs; [causing] injury or killing someone.
