As a professional exhibition that receives global attention in 2017, EXPO 2017 Astana is scheduled to take place between June 10 and September 10, 2017 in Astana, Kazakhstan. The Expo's theme is "Future Energy" and it will be the first time that World Expo is to be held by a Central Asian country.
Upon arrival in Astana City, you will find that a huge globular building is very eye-watching—it is the landmark building of this Expo, where the national pavilion of Kazakhstan is located. According to the sponsor, the building is so far the largest globular one in the world boasting a diameter of 80 meters and a height of 100 meters, with pavilions of other countries evenly distributed around it in a ring shape. It is learned that Zoomlion, a Chinese equipment manufacturing enterprise, has made remarkable contributions in building this grand pavilion with over ten models of engineering machinery products, whose highly efficient, precise and stable performances help a lot in building the pavilion, showing the world the force and charm of products made in China.

According to the architect from Kazakhstan, the construction of the main pavilion of Kazakhstan puts especially strict requirements on the engineering equipment. By report, the main pavilion of this Expo is contracted by SEMBOL CONSTRUCTION to build, one of the top three construction giants in Kazakhstan. Twelve large-tonnage Zoomlion tower cranes, seven Zoomlion truck cranes and one Zoomlion bulldozer have participated in the pavilion construction, among which four Zoomlion D1100-63 are the super-large tower cranes with the maximum hoisting capacity in the Central Asia.
“This kind of design and manufacturing requires such super-large tower cranes as Zoomlion D1100-63 to meet the demands of working conditions.” According to the principal of Zoomlion, D1100-63 is a new model of self-climbing tower crane features superstructure slewing, double lifting points, level jib and horizontal trolleying. With a hoisting capacity of 9.8t at the 80m jib end, the tower crane adopts variable frequency stepless speed-regulating motor to significantly optimize the system’s running stability and improve positioning accuracy, making operation easier and more user friendly. Meanwhile, PLC (programmable logical controller) is used to control all actions, thus improving the reliability and safety of the whole crane.
