Full of dominance! Zoomlion 2,000-ton truck crane!
Thread Content
The 2000-ton class all-terrain crane, which is rare even in China and around the world, has been reported by some media to be the only all-terrain crane in existence today that can be used for installing 3MW wind turbines thanks to its telescopic main boom. By equipping it with a specially designed wind turbine boom capable of fine adjustments, it can handle the installation of all wind turbines with a capacity of 3MW or less. In heavy-duty operations, its telescopic boom enables it to lift large equipment such as chemical towers and metallurgical blast furnaces weighing thousands of tons.
The QAY2000 was put into service in September 2012; compared to the numerous thousand-ton-class machines owned by Sany and XCMG that are already in use in various lifting projects, the QAY2000 had to face many difficulties before it could be utilized effectively.
During the more than 3 years of waiting, QAY2000 successively completed 5,000-kilometer driving tests at the Xibozizi test site, as well as extreme load tests with lifting moments of 6,000 ton-meters and 7,500 ton-meters, striving for continuous improvement. QAY2000 has attracted significant attention from the industry; aside from its extremely high lifting capacity, the various innovative technologies adopted for the first time are also a focus of interest in this sector.
A honeycomb frame structure that enables more reasonable force distribution throughout the vehicle and a more even stress distribution； A 12-axis all-terrain chassis with 9 axles and 3 auxiliary axles, featuring real-time synchronization of the front and rear power systems as well as coordinated steering; it overcomes the power limitations associated with ultra-large vehicles while complying with road regulations, allowing a payload weight of up to 325 tons ； The modular self-disassembly and assembly technology can reduce the current average industry time of 6 hours for such processes to 4 hours ； In addition, it features a leg structure with an oval cross-section, a leg cable deformation-resistant structure, and a variable-amplitude fly arm structure designed for the wind turbine lifting process.
Wow, a 2,000-ton truck crane – what a huge chassis is required for that.
In May 2016, the Zoomlion QAY 2000-ton all-terrain crane made its debut in a wind power project in Ningxia.
Dominant, give a like.....
