Abstract

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.
