China's first independently developed super-large hydraulic¹ pile hammer passed its testing stage in April, breaking the monopoly of foreign countries with such machines, cctv.com reported on May 8.

 

央视网5月8日报道，中国首个自主研发超大型液压打桩机在四月通过测试阶段，打破了外国在这一领域的垄断。
 

 

The pile hammer, with a height of 22 meters and weight of 430 tons, was developed and produced by the Taiyuan Heavy Machinery² Group Co., Ltd.

 

For a long time, super-large hydraulic pile hammers, which are indispensable in offshore³ operations, were monopolized⁴ by German and Dutch enterprises. However, after seven years of effort in research and overcoming technological⁵ difficulties, the monopoly has been broken by the Chinese enterprise.

 

The China-made pile hammer not only boasts outstanding performance, but also has an advantage in price and after service, according to the Chinese enterprise.

 

For example, in the past, China had to import such machines from foreign enterprises. If something went wrong, the maintenance usually took about half a year meaning the project progress was delayed.

 

However, the independently developed machine is not only conveniently maintained, but is also 30 percent cheaper than imported ones on the premise⁶ of meeting the international standard, said a client of the enterprise.
