　　On Friday morning, inside a smart factory in Zhangyan town, Jinshan district in Shanghai, a heavy-duty industrial robot made history. At a Guinness World Records certification event in Shanghai, official adjudicator Hu Xiaowen announced that a CR5000-3700 heavy-duty industrial robot self-developed by Shanghai Chaifu Robot Co had achieved a load capacity of over 5,000 kilograms, officially setting a new Guinness World Record for the heaviest industrial robot by load capacity, thepaper.cn reported.

　　In the heavy-duty robot segment, Chaifu"s CR5000-3700 fills a critical gap in China"s high-end offerings, delivering comparable performance with superior cost efficiency and localized service to help secure key industrial supply chains, according to a statement released on the Guinness World Records official website.

　　The achievement makes the robot the world"s strongest industrial robot in terms of load-bearing capability, and represents a breakthrough for China"s high-end equipment manufacturing sector, according to Chinese analysts.

　　The previous record was held by Japan"s Fanuc Corporation which set the benchmark in 2016 with a load capacity of 2,300 kilograms. The new record set by the Chinese firm more than doubles that figure, pushing the global ceiling for industrial robot load capacity to a new level, according to thepaper.cn.

　　The Global Times learned from the company that the CR5000-3700 is designed for extreme heavy-load, high-precision and high-risk operations in industries including heavy manufacturing, port machinery, rail transit, tunnel construction, aerospace, new energy, nuclear power, metallurgy and chemicals.
