1, the largest wheel crane in the world
Xugong QAY1200 crane
Using nine axis all ground chassis, five axis drive, full axis steering, the imported 480KW Mercedes engine has a strong driving force, the maximum driving speed of the chassis is up to 75Km/h, the maximum climbing slope is 40%, the leg full extension can reach 13*13m; the maximum lifting torque of the QAY1200 is 3600t*m, the eight section telescopic main arm is full extension to 105m, and the amplitude of the amplitude pair arm is up to 114 M, equipped with double-rate lifting device can effectively improve the lifting performance of the boom system, with a combination of six boom system can adapt to different operating conditions.
2. The world's longest arm rack pump
ZOOMLION ZLJ5910THBS 101-7RZ pump car
Carbon fiber composite arm frame technology, 101 meters and 7 bridge 7 arm, carbon fiber technology to reduce the quality of the arm more than 40%, the traditional steel arm is easy to eliminate the potential fatigue cracking. The total quality of hydraulic cylinders incorporating carbon fiber technology will also be reduced by more than 15%, and the strength and life expectancy will be improved. The strength of high strength aluminium alloy ceramic concrete pipe is higher than that of traditional alloy steel, the weight of double-layer pipe is reduced by 40%, the service life is over 60 000 m3, and the compressive strength is over 17 MPa.
3. The largest floating crane in the world
Samsung 5
Double arm, Twin Towers (character frame), eight hook giant floating crane, the maximum weight of 8000 tons, lifting height up to 120 meters on the surface of the water, hanging load of 8000 tons of maximum swing up to 57 meters out of port. Each hook can be operated individually or jointly. The swing can reach 20 degrees, and the swing of the left and right swing can reach 15 degrees. With the use of the balance beam, the working conditions can reach dozens of kinds.
4, the world's largest loaded dump railway freight car
100 ton dump railway freight car of China South car
The vehicle adopts pneumatic, hydraulic, electrical and mechanical integrated technology for wireless remote control and ballastballastballast control system, and realizes many innovations in car body structure, frame material, welding technology and so on. In addition, the low power bogie with excellent performance has the characteristics of uniform load on each wheel, light weight under the spring and good resistance to diamond stiffness.
