CHANGDE, China, Oct. 28, 2021 /PRNewswire=KYODO JBN/ --
The world's largest top-slewing tower crane, W12000-450, has rolled off the
assembly line at the intelligent tower crane manufacturing base of Zoomlion
Heavy Industry Science & Technology Co., Ltd. ("Zoomlion"; 1157.HK) in Changde,
Hunan Province. Zoomlion especially designed and built the model for the
world's largest road-rail cable-stayed bridge project, the Changzhou-Taizhou
Yangtze River Bridge integrating an expressway, ordinary highway and inter-city
railway.
The W12000-450 weighs 4,000 tons with a rated load moment of 12,000
tonne-meters. It's the first top-slewing tower crane exceeding 10,000
tonne-meters in the world, and has a maximum lifting weight of 450 tons and
maximum lifting height of 400 meters, which is the equivalent of lifting 300
cars to a level of 130 floors in one go.
The key technologies of building super-large tower cranes are complex with high
requirements of safety and reliability. Zoomlion has taken on the challenges of
technological innovation and manufacturing requirements to venture into the
unknown and set new records.
"In the absence of structural patterns to follow, we re-established a
calculation platform for structural rigidity, stability and modal analysis,"
introduced Tang Shaofang, Vice President of Zoomlion and General Manager of
Zoomlion Construction Hoisting Machinery Company. "The W12000-450 tower crane
has adopted several of Zoomlion's self-developed technologies including full
penetration T-joint welding technology and conquered technical difficulties
such as ultra-thick plate weld cracking, enabling the W12000-450 to not only
achieve super strong lifting performance reaching 10,000-tonne-meter level, but
also guarantee safety and reliability throughout the processes of transporting,
assembly/disassembly and operation."
The W12000-450 is produced in the world's largest intelligent tower crane
factory. According to plans, the factory will be manufacturing construction
hoisting machinery products covering the range from 80 to 20,000 tonne-meters.
It's fully digitalized to integrate big data analysis, industrial internet,
information systems, visualization and more to achieve full-coverage networking
and man-machine interaction.
Through intelligent, flexible assembly tools, the W12000-450 was manufactured
in four months, compared to traditional manufacturing technology that would
take at least 12 months.
The demand for super-large tower cranes is increasing as construction parts are
heavier, buildings are taller, and bridges are spanning wider. The launch of
W12000-450 will not only bring the latest solution for heavy industries, but
also showcase Zoomlion's industry-leading capabilities in the R&D, design and
manufacturing of large tower cranes.
