what mechanism towbarless tractors have while towing the aircraft when there is a risk of steering failure?
like normally towbar tractors if there is a steering mechanism failure,towbar will break to prevent damage to nose landing gear.but in case of towbarless tracors,its holding the wheels from both sides tightly..so how do it work when ders a steering mechanism failure evenif the steering pin is installed??

Good Question
I was a Crew Chief On the KC-135R Airframe for years in the air force so i have towed a few aircraft. And while i do not know all the specs, i can formulate a fairly educated guess.
Think of it like this. In a conventional tow bar, the bar couples to the piece that attaches to the steering collar with a set of sheer bolts that are designed to sheer when the back pressure reaches x amount. ( the amount of pressure needed to sheer the bolts is airframe specific.)
I would say that the barless tractor would have a similar setup (at least in theory) I think it couples to the nose gear with a variable pressure setting that could be adjusted by the operator depending on the airframe he is towing, and should the back pressure reach (x) amount the connection to the nose gear would pop lose, no harm done.
