On the afternoon of February 28, 2008, the completion of another towering structure within the Zoomlion Science and Technology Park marked a significant milestone in the development of Zoomlion’s National Technology Center. This new high-rise, serving as a test platform for the National Key Laboratory's Integrated Transmission Laboratory, is set to play a crucial role in advancing the research on common technologies for large inertia hoisting systems.
To address the industry-wide challenge of short-lived main hoisting wire ropes, Zoomlion’s National Technology Center formed a dedicated research team in 2007. Following over six months of intensive technical exploration, the team successfully developed a specialized test tower designed for large inertia hoisting mechanisms. This achievement represents a major breakthrough in improving the durability and performance of critical lifting components.
The newly constructed test tower stands over 50 meters tall, with a maximum single-rope test weight exceeding 20 tons. It is capable of meeting the experimental requirements for most of the company’s current product lines. By simulating real-world working conditions of construction machinery, the platform tests and verifies the performance of large inertia hoisting systems, aiming to identify optimal solutions that enhance system efficiency and reliability.
Designed with a modular approach, the test platform allows flexible configuration based on different testing needs. The hoisting mechanism can be operated using various drive modes, including electric-mechanical, full hydraulic, electro-hydraulic proportional, and frequency conversion systems. The platform features PLC-based intelligent control, managed through a large, color LCD touch screen with full Chinese interface. It automatically records the entire testing cycle and includes multiple layers of safety protection, along with audio-visual alarm functions. These features make the operation of the test platform more intuitive, efficient, and reliable, ensuring stable and safe performance during all testing procedures.
In addition, the platform integrates advanced technological solutions, further enhancing its capabilities and supporting future innovations in the field of construction machinery.
