A giant gully-crossing vehicle for polar scientific expeditions, including a gully-crossing bridge and a vehicle body. The vehicle body includes a stage and a travelling portion. The stage includes a top platform, a front bottom plate, a rear bottom plate and a multifunctional lock platform assembly. The front bottom plate and the rear bottom plate are capable of sliding independently relative to the top platform. The travelling portion includes a first travelling component, a second travelling component, a third travelling component, a fourth travelling component, a fifth travelling component and a sixth travelling component which are symmetrically provided at left and right sides of the stage and below the stage. Bridge bodies of the bridge components can be assembled to two gully-crossing bridges, and are connected to the multifunctional lock platform assembly when crossing gullies.

UGV bridging system includes a first end of a first elongated span of a hinged bridge structure disposed on a deployment support bracket which is secured to a UGV. A second elongated span is hingedly supported at a second end of the first elongated span opposed from the first end. A tension element applies a tension force to the first elongated span at a location intermediate the first and second ends. The tension force secures the first elongated span in a stowed position adjacent the deployment support bracket. A retention element associated with the deployment support bracket prevents the second elongated span from rotating about the hinge axis in response to a spring bias force. Deployment involves pivoting the first elongated span and concurrently releasing the second elongated span from the retention element in response to the extending.
