Zusammenfassung:	A tow vehicle for aircraft comprises a nose gear support assembly that can be raised and lowered relative to the vehicle about a first pivot axis. The support assembly can comprise a base portion and nose gear support portion pivotal about an upright axis relative to the base portion. Bearings can be positioned inwardly of the periphery of the support portion to support the support portion on the base portion. The bearings can be positioned partially in pockets provided in the base portion and in recesses in the support portion. A torque sensor can be coupled to the base portion and support portion and be operable to provide an output signal indicative of the torque between these components. An indicator, such as an alarm, can indicate when the torque exceeds first and second thresholds and can be operational to remain on if a second higher threshold is exceeded until, for example, a supervisor or other authorized individual turns off the indicator.
