Zoomlion Heavy Industry Science & Technology Co., Ltd. has unveiled the ZT82J straight-boom aerial work platform, recognized as the world's tallest model in its category with a maximum working height of 82.3 meters. The machine received an Outstanding Flagship Product Award at the company's Seventh Science and Technology Innovation Conference, addressing demand for equipment capable of operating above 80 meters for major infrastructure projects. This development underscores Zoomlion's focus on high-end manufacturing and technical innovation to support global expansion.
The R&D team, led by product manager He Jipeng at the Aerial Work Platform R&D Center, faced the challenge of balancing overall dimensions and total weight while completing the structural layout. The scope included an ultra-long, specially shaped lightweight boom, a box-type turntable, and a high-capacity chassis. The goal was to reduce weight while significantly improving structural rigidity to ensure bending and torsional resistance under 82.3-meter lifting conditions and suppress platform sway.
Engineering Breakthroughs
With no mature industry example to follow, the team encountered bottlenecks including insufficient layout space, excessive weight, and inadequate rigidity. Weight reduction, overall dimensions, and structural rigidity involved competing requirements. After over ten rounds of simulation, the team developed a proprietary multi-edge boom cross-section and evaluated multiple telescoping configurations to optimize the overall structure. This ensured vertical and lateral stiffness while balancing weight-reduction targets with structural capacity.
Building on the lightweight boom, the team integrated turntable and chassis optimization. Simulation identified weak stress points, precisely optimized plate cross-sections, and reduced redundant steel while maintaining safety margins. This achieved a lightweight upgrade, enhanced anti-fatigue and anti-overturning performance, and completed a structural breakthrough for ultra-high working height equipment.
Conference Context
The award was presented during the Seventh Science and Technology Innovation Conference, which showcased over 130 innovations across AI, intelligent equipment, green technology, and high-end manufacturing. The event recognized 84 science and technology achievements, with total bonuses reaching 22 million yuan. Zoomlion reported that digital, intelligent, and green products accounted for 74.5% of product sales in 2025, with international revenue reaching 30.5 billion yuan, representing roughly 59% of total sales.
