SHANGHAI, July 22,
2024 /CNW/ -- SANY Group ("SANY") is making key
breakthroughs in the construction of the Shiziyang Bridge, a major
construction project in China's
Guangdong-Hong Kong-Macao Greater
Bay Area ("GBA"). Four units of SANY pump trucks have finished
pouring the last layer of the right bearing platform of the
Shiziyang Bridge's east tower, making the successful completion of
the bearing beam platform construction of the world's largest
double-deck suspension bridge.
The Shiziyang Bridge has a total length of 35.1 kilometers. Upon
completion, it will become an important passage connecting the east
and west banks of the Pearl River Estuary, promoting the
high-quality development of the GBA as part of the "golden
inner bay."
SANY equipment completes east tower bearing platform
The Shiziyang Bridge, a 2,180-meter-long double-deck steel truss
suspension bridge, crosses the Pearl River without bridge piers in
the center of the estuary, and it has set five world records for
having the longest span, the most number of lanes, and highest main
tower, and for having the biggest main cable scale, and anchor
foundation.
The east tower bearing platform has two circular structures that
are 40 meters in diameter and 9 meters in height, boasting a gross
volume of 25,000 cubic meters. They use the C45 high-strength
concrete, a huge construction challenge for the equipment. The four
units of SANY pump trucks operated for 22 hours non-stop and
successfully completed the task.
Elevating construction efficiency with technological
innovation
SANY's pump trucks feature a stepless pressure pumping system
and digital main valve technology, improving direction changes by
20%—enabling an extra load of materials to be pumped every hour.
The system prevents pipe blockages and ensures intelligent,
energy-saving operations. Additionally, the boom's active
suppression technology limits end amplitude to within 20
centimeters, ensuring smoother truck operation.
In the meantime, the all-new power transmission change saves
fuel cost significantly by lowering the engine operating speed by
300rpm, saving about 40,000 yuan in
fuel costs for the operating volume of 60,000 cubic meters per
year.
"SANY is dedicated to the mission of 'Quality Changes the
World,' supporting global infrastructure with innovative,
efficient, and green technologies. The successful completion of the
Shiziyang Bridge's east tower bearing platform showcases SANY's
leadership in technological innovation and construction efficiency,
setting new industry benchmarks," said Xiang Wenbo, Rotating
Chairman of SANY Group.
