顶推运输起始于美国内河,海上顶推开始于第二次世界大战后。它是一种新型的先进技术。近十年来,解决了轮-驳之间的联接技术,研制了能适应海上恶劣工况及不同工作要求的液压联接装置,使它以独特的面貌出现于海洋。 The push transportation started in the river of the United States. The launch of the sea began after World War II. It is a new type of advanced technology. In the recent ten years, the connection technology between wheels and barges has been solved and a hydraulic coupling device that can adapt to the harsh conditions at sea and different work requirements has been developed so that it appears uniquely in the ocean.
