-The world’s largest tower crane rolls off the production line of Zoomlion’s intelligent tower crane factory
CHANGSHA, China, April 21, 2023/PRNewswire/ — On April 20, the world’s largest tower crane, integrating 158 innovative scientific research achievements and 305 invention patents, rolled off the production line of the smart factory of Zoomlion tower cranes in Changde. This world record-breaking crane marks a breakthrough for Chinese construction machinery maker Zoomlion in its global expansion drive in the field of advanced manufacturing.
Advanced technologies help create “the world’s largest and strongest tower crane.”
The R2000-720, the world’s largest tower crane, can lift 500 cars up to 130 stories with its rated torque of 20,000 t/m, capacity of 720 tons and height of 400 meters. It integrates 158 innovative scientific research achievements and 305 invention patents, including more than 60 core technologies and 12 world-firsts. After delivery, the 2000-720 will be used in the construction of the world’s longest three-tower cable-stayed bridge, the Ma’anshan Yangtze River Highway-Railway Bridge.
“The R2000-720 has made innovations and breakthroughs in weight balance, structure, intelligent control, and other technologies, solving multiple global challenges for ultra-large tower cranes in extremely complex working conditions, such as strong wind, high humidity, and load heavy, which means it’s not only the biggest tower crane in the world, but also the strongest,” a Zoomlion spokesperson said.
The R2000-720 uses Zoomlion’s pioneering movable counterweight technology to move precisely with the lifting torque, improving lifting performance by more than 60%. The R2000-720 also innovates by using high-load capacity lightweight structure and high-strength split structure, and reduces the upper structure of tower cranes by more than 20% compared to conventional solutions, making transportation easier. , installation and disassembly.
In addition, Zoomlion has invested heavily in intelligent control technology to improve the agility of tower cranes. To do this, it has developed an advanced control system that uses 50 intelligent technologies to achieve a response in milliseconds.
smart production line
Despite being the world’s largest tower crane, the R2000-720 project had a relatively short delivery cycle of just 8 months from design to production at Zoomlion’s intelligent tower crane factory in Changde. This was achieved through intelligent manufacturing, in which Zoomlion controlled eight key control projects, evaluated and developed 18 parallel projects, and set a new lead time record by being two months faster than the W12000-450.
Zoomlion’s success in producing the R2000-720 is the result of 67 years of continuous innovation in the field of engineering machinery. This has enabled them to create the world’s leading platform for research, development and design in this field, and build the world’s largest smart tower crane factory.
Zoomlion Smart Tower Crane Factory has 40 intelligent production lines, including 12 unmanned black light production lines, equipped with flexible tooling, high-precision heavy machining equipment, and nearly 1,000 tower crane-skilled craftsmen. Thanks to intelligent manufacturing, Zoomlion has made quantitative and qualitative advances in the manufacturing capacity of large tower cranes. The factory can fully cover the production of 13 models of large tower cranes (500-20000 t/m), meeting almost all the needs of today’s large hoisting projects.
