Recently, the Ministry of Industry and Information Technology (MIIT) announced the proposed list of typical cases for the 2024 Industrial and Information Technology Quality Improvement and Brand Building initiative. Two Zoomlion projects were selected as typical cases in the quality management capability and reliability improvement categories respectively, highlighting the company's strong technological innovation strength and quality control capabilities.

The selection of these typical cases aims to further enhance industrial and information technology quality management capabilities, accelerate the application of quality technology innovation, improve product reliability, build more internationally influential "Made in China" brands, and strengthen the summary of typical experience and the promotion of outstanding cases. A total of 100 typical cases were selected nationwide, divided into four categories: quality management capability, quality technology innovation application, reliability improvement, and brand building.

Among them, the "Six Horizontal and Six Vertical" hierarchical matrix quality control model was independently explored and pioneered globally by Zoomlion, achieving hierarchical and tiered control of quality for super-large tower cranes and filling the gap in quality control for super-large tower cranes. This model summarizes the complex production process of super-large tower cranes into six key modules, and reasonably sets six quality processes according to the product characteristics of super-large tower crane components, achieving control over each key characteristic point in the production process. Through the self-developed quality management information system Z-QMS, digital quality control is realized. Through the application of this project, Zoomlion's tower crane quality management level has been further improved, achieving comprehensive quality control and the "zero defect" goal for super-large tower cranes.

The reliability solution for luffing balance valves, based on research into the ultra-fine control conditions of high-pressure, large-flow, variable-load operation of super-large tonnage cranes, involved targeted development through analysis and research of specific operating conditions. It thoroughly solved the challenge of ultra-fine control under high pressure, large flow, and variable load for super-large tonnage cranes, effectively improving the adaptability of various balance valves to the hydraulic system conditions of host equipment. This greatly enhanced the reliability of the host hydraulic system and significantly improved host controllability. Especially for super-large equipment, product consistency and reliability were substantially improved, reaching world-advanced levels.

With a holistic approach covering the entire lifecycle and value chain, Zoomlion has established a quality management system with a unified framework and deeply integrated artificial intelligence technology and big data platform technology, achieving digital and intelligent quality control and greatly improving product consistency and reliability. Zoomlion will continue to adhere to "pursuing ultimate quality," create higher-quality products that better meet demand, and make greater contributions to building a "Quality Power."
