瑞典研制成功了一种新式的重型货物运输系统。利用这个系统,运输装置在一层空气薄膜上滑过,可轻易而安全地移动数百吨重的货物。这个运输系统既不需要轨道、机座,也不需要其他固定的设备,因而也不会产生噪音和排出废物、烟气。整个运输装置能灵活地旋转360°,并且只要通过一个限制开关的开度很容易地加以控制。一个标准化了的直接控制的运输装置, Sweden developed a new type of heavy goods transport system. With this system, the transport unit slides over a layer of air film and can easily and safely move hundreds of tons of cargo. This transport system does not require tracks, stands, or other fixed equipment, and therefore does not generate noise and exhaust waste, flue gas. The entire transport unit can be flexibly rotated by 360 ° and can be easily controlled simply by limiting the opening of the switch. A standardized, direct-controlled transport unit,
