On March 7, 2025, the China Construction Machinery Association (hereinafter referred to as the Association) organized an appraisal meeting in Changsha, Hunan Province for three technological achievements completed by Hunan Zoomlion Intelligent Aerial Work Machinery Co., Ltd. (hereinafter referred to as Zoomlion Intelligent Aerial Work Machinery): "Key Technologies and Applications for Full-Scenario Safety of Aerial Work Platforms," "Key Technologies and Applications of Distributed Electro-Hydraulic Integrated Control Systems for Aerial Work Machinery," and "Key Technologies and Applications of Intelligent Installation Equipment for Inter-Story Building Curtain Walls."

Industry experts from the Association, China Academy of Machinery Science and Technology Group Co., Ltd., CABR Beijing Research Institute of Construction Mechanization Co., Ltd., Hunan Provincial Machinery Industry Association, Huazhong University of Science and Technology, Central South University, Taiyuan University of Science and Technology, and other institutions attended the meeting.

The key technologies for full-scenario safety of aerial work platforms are applied to aerial work platform equipment. Building on passive safety technologies, they include active safety control technology for complex ground-air scenarios, slewing vibration reduction safety technology for aerial work platforms, and intelligent safety wearable technology for aerial work platforms. They are adapted to more complex working conditions and, in particular, achieve functions such as active detection of ground potholes, active identification of aerial obstacles, active vibration reduction during platform slewing, and active warning of battery abnormalities.

The key technologies of distributed electro-hydraulic integrated control systems for aerial work machinery consist of distributed-architecture electro-hydraulic integrated control technology for aerial work platforms, broadband high-response electro-hydraulic pump load matching technology, and multi-action compound high-precision control technology for distributed hydraulic platforms. Through the electro-hydraulic distributed architecture of aerial work platforms, the re-planning and layout of electro-hydraulic control for aerial work machinery are completed. Based on the broadband high-response electro-hydraulic pump load matching technology, the electro-hydraulic pump control system is kept in a low-energy-consumption and high-power range. Based on the multi-action compound high-precision control of distributed hydraulic platforms, the electro-hydraulic dual-pump coupling control technology for aerial work machinery is developed, ensuring low coupling pressure loss in the machine's compound actions and fast action response, thereby improving the machine's endurance.

The key technologies of intelligent installation equipment for inter-story building curtain walls consist of vision-guided automatic alignment and control technology for curtain wall installation and safety control technology for multi-axis robotic arms operating in narrow spaces. They are adapted to complex working conditions in the field of building curtain wall installation and have functions such as lifting, adsorption, automatic alignment, posture adjustment, and intelligent operation. In particular, they achieve high-precision automatic installation and integrated lifting and installation of 800 kg-class curtain walls, with significantly improved efficiency.

The experts inspected the products and production sites, listened to reports from the completing units, and reviewed the relevant technical materials. After questioning and discussion, the appraisal committee concluded that the three projects are highly innovative, technically difficult, and have independent intellectual property rights, with overall technical performance reaching the international advanced level and some technologies reaching the international leading level.
