The non-continuously moving state lies on the vehicle's structural characteristic. This air-cushion vehicle has two platforms, which are connected by two hydraulic cylinders. When it moves, one platform is fixed on ground as the base platform, and takes the other one as moving platform, then the vehicle can go forward by alternate movement of these two platforms. So the push-pull air-cushion vehicle is a self-propelled vehicle.

它的非连续运动形态取决于其结构特点，该气垫车由两个对称的子平台组成，中间通过液压油缸相铰接，运动时总是固定其中一个平台作为基础平台，而将另一个平台作为运动平台，基础平台通过液压缸推出或拉进运动平台交替动作，实现运动，因此推拉式气垫车是一种自走式气垫车。
