丹麦克劳尔公司(Kroll Giant Cranes A/S)推出了其迄今最大的起重机——K-25000型塔式起重机,起重量可达400t。这种巨型塔机,最大吊钩扬程为108m,最初是为核电站的建设施工用而设计的。据计算,一座发电量为1MW 的核电站建造成本大约20亿美冗,如果施工工期缩短一个月,就可以节约1000万美元左右。克劳尔公司清楚地认知到,建造这种特大型塔机是不经济的,但是如果这种塔机能够大大有助于缩 Kroll Giant Cranes A / S has launched its largest crane, the K-25000 tower crane, with a capacity of 400 tons. This giant tower crane, the maximum lift hook 108m, originally designed for the construction of nuclear power plant and use. It is calculated that a nuclear power station with a capacity of 1MW will cost about 2 billion U.S. dollars to build. If the construction period is shortened by one month, it will save about 10 million U.S. dollars. Claauer clearly understands that it is uneconomical to build such extra-large tower cranes, but if such a tower crane can greatly help reduce
