Kelude Heavy Industry Earns AAA Digital-Industrial Rating for LXD/DXT Cranes
Kelude Heavy Industry has passed the AAA-level classification rating of the Integration of Informatization and Industrialization (III) Management System, earning national recognition for its digital–industrial integration maturity.
The III Management System rating — a national standard that measures how mature a manufacturer's digital transformation is — evaluates the deep integration of information technology and industrialization. Kelude Heavy Industry recently passed the AAA-level classification, the highest grade available, with coverage spanning the full product lifecycle of overhead cranes: R&D and design, manufacturing, supply chain management, and after-sales service. This places the company at the forefront of digital–industrial integration in its sector. This article breaks down the assessment from four angles: the standard system behind the rating, the technical requirements for AAA, the implementation process, and the measurable business benefits.
What the III Management System AAA Rating Covers
The III Management System was developed by China's Ministry of Industry and Information Technology. The governing standards are GB/T 23001-2017 (Requirements for the Integration of Informatization and Industrialization Management System) and GB/T 23006-2022 (Grading Requirements for New Capabilities under the Integration of Informatization and Industrialization Management System). Ratings are issued in three ascending grades — A (foundational), AA (unit-level), and AAA (process-level) — with AAA being the highest currently attainable.
The core requirement for AAA is that a company's new capabilities in a digital environment reach "process-level" maturity — meaning key business processes run collaboratively across departments and systems, with data flowing automatically between process steps.
Four Capability Domains Assessed at AAA Level
The AAA assessment covered four core capability domains for this overhead crane manufacturer:
Digital Product R&D and Design: Using a PLM system for 3D parametric design and modular configuration of overhead cranes. The automatic mapping rate across the three-tier BOM transition — from design BOM to process BOM to manufacturing BOM — reaches 97.3%, and variant design cycles have been cut from 3 days to 1 day.
Digital Manufacturing and Production Control: The MES system covers six workshop processes — cutting, welding, machining, assembly, coating, and final assembly. Data acquisition coverage for key processes stands at 92%, and electronic work orders are pushed directly to workstation terminals, enabling a paperless workflow.
Digital Supply Chain Collaboration: The ERP system enables online collaboration with 30 core suppliers on purchase orders and delivery schedules. Suppliers confirm delivery times and upload shipping documents within the system, improving purchase arrival plan accuracy from 75% to 93%.
Digital After-Sales Service: The remote operation and maintenance platform provides real-time operation monitoring, AI-based early warning, and intelligent maintenance scheduling for delivered cranes — with more than 200 units now connected.
Implementation Timeline and Assessment Outcome
The III Management System implementation spanned 14 months, divided into three phases: system establishment, operation, and assessment.
System Establishment (4 months): Developed the III management system documentation in line with GB/T 23001-2017 and GB/T 23006-2022, including 1 management manual, 12 procedure documents, and 23 work instructions.
Operation Phase (8 months): Rolled out the system across the entire company. Assessment Phase (2 months): The certification body conducted both document review and on-site audit.
The final assessment confirmed that Kelude Heavy Industry meets AAA (process-level) requirements across all three dimensions: operation of the III management system, development of new capabilities, and measurable outcomes of digital transformation. Two highlights drew specific praise from the audit team: first, the data integration rate between PLM and ERP — design BOMs are automatically pushed to the ERP system to generate purchase plans without manual intervention — which is at an industry-leading level; and second, the remote operation and maintenance platform for after-sales service, which sets a benchmark in the lifting appliances segment.
Measurable Business Benefits of the AAA Rating
The AAA rating has delivered tangible results: order delivery time has been reduced from 42 days to 28 days, product defect rates have dropped from 3.2% to 1.8%, comprehensive energy consumption per RMB 10,000 of output value has fallen 12% year-over-year, and new product development cycles have shortened from 45 days to 28 days. Beyond operational gains, the AAA certificate also qualifies the company for smart manufacturing support funds and tax incentives in certain regions, and serves as third-party proof of digital capability when bidding on large enterprise projects.
FAQ
Q: What's the difference between the III Management System AAA rating and a provincial-level Smart Manufacturing demonstration enterprise designation?
A: The III AAA rating is a management system certification under a national standard framework, focused on how systematically a company builds and sustains new capabilities in a digital environment. A provincial Smart Manufacturing demonstration enterprise, by contrast, is a recognition awarded by local government based on the practical impact of smart manufacturing technologies and the company's role as an industry benchmark. They evaluate different dimensions and are issued by different bodies, but the two designations reinforce each other when it comes to validating a company's digital transformation progress.
Q: Is the AAA rating applicable to other companies in the overhead crane industry? What value does it offer to SMEs?
A: The III Management System is a generic standard applicable to all manufacturing sectors, including the overhead crane industry. SMEs can start at a grade that fits their scale and resources — for companies with annual output below RMB 50 million, AA is a realistic and pragmatic target. It's worth emphasizing that the rating is not about how many IT systems you have; it's about how genuinely your business and digital tools are integrated. A well-run ERP + MES combination that achieves full data connectivity across design, procurement, production, and delivery can reach AA or even AAA level.
Q: How long is the certificate validity and re-audit cycle for the Two-Systems Integration Management System?
A: The certificate validity for the Two-Systems Integration Management System is 3 years. A surveillance audit is conducted annually, focusing on the maintenance of new capabilities and the effectiveness of continuous improvement. A license renewal assessment is required before the validity period expires.
