Bestsellers among Belt and Road Countries -- China-made Shield Machine
“When we ask about the national bestseller from Henan in countries along the Belt and Road, the shield tunneling machine produced by China Railway Engineering Equipment Group Co., Ltd (CREG) is the best one,” said Wang Dujuan, an NPC deputy and deputy general manager of CREG on May 17. This is her innermost thoughts to express to Xi Jinping at the coming NPC and CPPCC sessions.

Designed by Henan, the shield tunneling machine is sold to the world and manufactured nationwide. In the three consecutive years of 2017, 2018 and 2019, the production and sales volume of CREG topped the world based on its “Henan-Global-Henan” industrial chains. Wang said that CREG had produced nearly 20 shield tunneling machines since the resumption from the pandemic on February 10.
Pointing at the world map, Wang, in her office, introduced the key products to the reporter, such as “No. Wendeng” (the world’s first compact hard-rock TBM with ultra-small turning radius) and rectangular shield tunneling machine with world’s largest diameter, which have been exported to 21 Belt and Road countries, including Algeria, Italy, Denmark, etc.
In assembly workshop, Wang pointed at a shield tunneling machine, saying “CREG and LYC Bearing Corporation have carried out key technology research and industrial assessments on domestic main bearing and reducer. Confirmed by the experts, the main bearing and reducer of the shield tunneling machine for 6-meter-grade subway can match the standard and requirements, as equipped with a “Chinese heart” to the domestic shields.”
As a cutter head, water could cut everything into pieces. The shield machine with new rock breaking technology of high-pressure water coupling is comparable with the depict in Kungfu novels. “The revolutionary transformation to the cutter head of the shield tunneling machines is a new answerback to the entrustment from President Xi,” said Wang.
