The walking mechanism of push-pull air-cushion vehicle includes two parts: push-pull mechanism and anchoring mechanism, both take hydraulic cylinders as driving components. So this walking mechanism has advantages of lighter weight and higher driving efficiency, it can work on many areas.

推拉式气垫车的行走机构包括推拉机构和抓地锚定机构两部分，它们都是以液压油缸作为驱动元件，通过液压传动实现伸缩动作的，这样既省却了轮式、履带式车辆笨重、复杂的行走机构，又大大提高了气垫车的驱动效率，能够适应各种复杂地表条件。

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。
