Zhengzhou Coal Mining Machinery (Group) Co., Ltd. (ZMJ) sets a new world's record 5 years later with the rolling off of its 155 10-meter-high intelligent hydraulic supports on June 13, whose manufacturing was highly digitalized. ZMJ sets a new world's record in this field through digital manufacturing since 2018, a year witnessing the birth of its 8.8-meter-high hydraulic supports.
The 10-meter-high intelligent hydraulic supports, 2.25 meters in width and 127 tons in weight for each, are designed based on the geological conditions of the 10-meter-deep mine of Shaanxi Caojiatan Mining Co., Ltd. Their height, working resistance and center distance rank first in the world. (Chinese source: Henan Daily Reporter: Luan Shan Hu Shutong Translator: He Menghe Proofreader: Li Wenjing)
