On March 7, 2025, the China Construction Machinery Industry Association (hereinafter referred to as the Association) organized and held three scientific and technological achievement appraisal meetings in Changsha, Hunan Province, including "Key Technologies and Applications for Full-Scene Safety of Aerial Work Platforms", "Key Technologies and Applications for Distributed Electro-hydraulic Integrated Control Systems for Aerial Work Machinery", and "Key Technologies and Applications for Intelligent Installation Equipment for Interlayer Building Curtain Walls", which were completed by Hunan ZOOMLION Intelligent Aerial Work Machinery Co., Ltd. (hereinafter referred to as ZOOMLION Intelligent Aerial Work Machinery).

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

The key technologies for the full-scenario safety of aerial work platforms are applied to aerial work platform equipment. They are active safety control technologies for complex ground-air scenarios, aerial work platform rotation vibration reduction safety technologies, and intelligent safety wearable technologies for aerial work platforms, which are developed on the basis of passive safety technologies. They adapt to more complex working conditions, especially realizing the functions of active detection of ground holes, active identification of high-altitude obstacles, active vibration reduction of platform rotation, and active warning of battery abnormalities.

The key technologies of the distributed electro-hydraulic integrated control system for aerial work machinery are composed of electro-hydraulic integrated control technology of the distributed architecture of aerial work platforms, broadband high-response electro-hydraulic pump load matching technology, and distributed hydraulic platform multi-action composite high-precision control technology. Through the electro-hydraulic distributed architecture of aerial work platforms, the re-planning and layout of the electro-hydraulic control of aerial work machinery are completed. According to the broadband high-response electro-hydraulic pump load matching technology, the electro-hydraulic pump control system is placed in the low-energy and high-power range. According to the distributed hydraulic platform multi-action composite high-precision control, the electro-hydraulic dual pump coupling control technology of aerial work machinery is developed to ensure that the pressure loss of the composite action coupling of the whole machine is small, the action response is fast, and the endurance of the whole machine is improved.

The key technologies of the intelligent installation equipment for interlayer building curtain walls are composed of visually guided automatic alignment and control technology for curtain wall installation, multi-axis robotic arm safety control technology for narrow space operations, etc. It is suitable for complex working conditions in the field of building curtain wall installation, and has functions such as lifting, adsorption, automatic alignment, posture adjustment and intelligent operation. In particular, it realizes the high-precision automatic installation and integrated lifting and installation functions of 800 kg-level curtain walls, and the efficiency is significantly improved.

The experts inspected the products and production sites, listened to the reports of the completion units, and reviewed the relevant technical materials. After questioning and discussion, the appraisal committee believed that the three projects were highly innovative, technically difficult, and had independent intellectual property rights. The overall technical performance reached the international advanced level, and some technologies reached the international leading level.
