Key security technologies for complex scenarios:
The leap from passive protection to active intelligent control
The safety protection of traditional high-altitude work platforms relies heavily on passive design, while the complex scenario safety key-technology system developed by Zoomlion has achieved active safety control under complex working conditions for the first time. This technology includes active safety control technology for complex ground-air scenarios, safety technology for rotating vibration reduction of high-altitude work platforms, intelligent safety wearable technology for high-altitude work platforms, etc. It adapts to more complex working scenarios, especially realizing functions such as active detection of ground pits, active recognition of high-altitude obstacles, and active vibration reduction of platform rotation.
Demonstration on site: Intelligent seat belt
In 2020, Zoomlion launched the ZT68J, a 68-meter straight arm high-altitude work platform, which truly combines the advantages of high working height, safety and reliability, smooth and fast movement, flexible and precise control, and strong power. In addition, ZT68J also applies modern sensing technology, IoT technology and other complex scene safety key technologies, adding artificial intelligence technologies to high-altitude operation machinery. Through various methods such as remote management platform, mobile app, and device control system, it can achieve fault alarm and diagnosis, and provide accurate safety warnings such as overload and tilt.
ZT68J has won the trust of customers with outstanding performance in execution cases such as the maintenance project of the Shanghai Fire Headquarters practical exercise building, the installation project of the Shanghai Jinling Petrochemical distillation tower, and the construction project of the Guangdong Jiangmen Archives Center.

Distributed electro-hydraulic integrated control technology:
Dual breakthroughs in energy efficiency and precision
Zoomlion has launched the world's first distributed electro-hydraulic integrated control system, achieving three major innovations: electro-hydraulic integrated control technology, wideband and high response electro-hydraulic pump load matching technology, and distributed hydraulic platform multi action composite high-precision control technology.
It completes the re-planning and layout of the electro-hydraulic control of high-altitude operation machinery through the distributed architecture of the high-altitude operation platform; According to the load matching technology of broadband and high response electro-hydraulic pump, the control system of the electro-hydraulic pump is placed in the low energy consumption and high power range; Based on the distributed hydraulic platform's multi action composite high-precision control, the development of electro-hydraulic dual pump coupling control technology for high-altitude operation machinery has been completed, ensuring that the coupling pressure loss of the entire machine's composite action is small, the action response is fast, and the overall endurance of the machine is improved
ZT28JE-V equipped with new generation distributed-drive electro-hydraulic integrated control technology
The ZT28JE-V electric straight arm high-altitude work platform equipped with this technology reduces the platform pipeline by nearly 70 meters, avoiding responsiveness problems caused by excessively long pipelines, and improving system responsiveness by more than 20%; Composite actions do not interfere with each other, realizing precise and efficient control, and the smoothness of composite actions is improved by more than 30%; Calculated based on 10 years of use, 14.1 tons of carbon emissions can be reduced during the usage process
Intelligent installation technology for building curtain walls:
Cracking the last meter problem in high-altitude construction
R-V800 high-altitude glass installation robot
The installation of curtain walls in high-rise buildings relies on manual hanging baskets for a long time, which is inefficient and high-risk. The intelligent installation equipment for interlayer building curtain walls, developed by Zoomlion, uses intelligent robot technology to achieve full automation process of lifting, suction, transportation, and installation. The key technologies of the intelligent installation equipment for interlayer building curtain walls include visual guided automatic alignment and control technology for curtain wall installation, and multi axis mechanical arm safety control technology that adapts to narrow space operations. It is suitable for complex working conditions in the field of building curtain wall installation and has functions such as lifting, suction, automatic alignment, posture adjustment, and intelligent operation. In particular, it has achieved high-precision automatic installation and integration of lifting and installation for 800kg level curtain walls, significantly improving efficiency.
SR-V800 high-altitude glass installation robot is carrying out glass installation
In the installation of glass curtain walls in the Zhonglian Smart Industry City Project, the SR-V800 high-altitude glass installation robot completed the installation of glass that is 6m long, 2.4m wide, and weighs 800kg in just 7 minutes. This task would require more than 10 people and an hour to complete manually. User feedback: "This is a key tool for the transformation of curtain wall construction from labor-intensive to technology intensive
