"Thumbs up for the Zhongrui ZG70 hydraulic grab, and thumbs up for Zhongrui's equipment leasing service." This is the assessment of the Zhongrui ZG70 trenching machine by the lessee Sichuan Hongshi Dingsheng. "With just one phone call, the fast and efficient one-stop service was reflected in every aspect—from equipment requirement matching, equipment transfer, arrival, commissioning, inspection, and maintenance to operator staffing, trenching results, and work efficiency. It was truly excellent!" In the early-started section of the Shenzhen Airport–Pingshan section of the Shenzhen Airport–Daya Bay intercity railway project, the Zhongrui ZG70 hydraulic grab, machine No. 20005, selected by the lessee Sichuan Hongshi Dingsheng, demonstrated strong work efficiency, low energy consumption, high efficiency, high precision, and high verticality. This not only earned Zhongrui Heavy Technology the "Excellent Equipment Award" but also won high praise from the general contractor, China Railway No. 3 Engineering Group, for its construction efficiency and progress on the project, truly achieving win-win cooperation among Zhongrui, Sichuan Hongshi Dingsheng, and the general contractor.

Since 2020, Zhongrui Heavy Technology, a wholly owned subsidiary of Yitong Teji, has developed an equipment leasing business to meet the development needs of the underground space market. "Satisfying customers' precise needs, providing thorough service, and ensuring that Zhongrui equipment undergoes pre-delivery maintenance and upkeep to achieve zero failures upon delivery, so it can start working immediately upon arrival on site, with high efficiency and high quality—these are the self-imposed prerequisites for our equipment leasing business," said Zhu Shouqian of Zhongrui's Equipment Leasing Department.
