随着我国远洋航运事业的发展。除了需要建造大批万吨级远洋轮外,还需要大力加强船舶维修这一重要环节,以保证海上铁路的畅通无阻。修船过去一直是一个比较薄弱的环节,其中缺乏大幅度门座起重机是重要原因之一。以我国南方较大的文冲船舶修造厂为例,由于原有起重设备幅度小,只能对停舶在码头的第一挡船进行维修吊装,而第二挡船要等第一挡船吊装完毕后再互易位置。这样修船效率低、周期长,远远不能满足国家修船计划的要求。为了迅速改变这种状况,1974年上半年我们与交通部文冲船厂组成三结合设计组,设计了我国
With the development of China’s ocean shipping business. In addition to the need to build a large number of 10,000-ton ocean-going vessels, there is also a need to vigorously strengthen the ship’s maintenance of this important part of the sea to ensure smooth sea. Ship repair in the past has been a relatively weak link, of which the lack of a substantial portal crane is one of the important reasons. Take the larger Wenchong Shipyard in southern China as an example. Due to the small amplitude of the existing lifting equipment, the first block ship that stops at the pier can only be serviced and hoisted while the second block ship has to wait for the first block ship After the lifting of the re-mutual position. This low efficiency ship repair, long cycle, far from meeting the requirements of the national ship repair plan. In order to rapidly change this situation, in the first half of 1974, we formed a three-tiered design team with Wenchong Shipyard of the Ministry of Communications to design a
