XCMG puts QAY 1200 to the test

Chinese manufacturer XCMG has been putting its new 1,200 tonne capacity all terrain type crane through its paces prior to its official launch.
More than 10,000 tests have been carried out on the QAY 1200 over the past 12 months, XCMG said, but, to prove reliability in lifting heavy loads, XCMG decided to put the nine axle vehicle through one final test - lifting a QY 160K truck crane, valued at RMB 8 million (US$ 1.3 million).
After a week of calculations and confirmation of the distance for the hanging point and fulcrum, the technical team finally determined the tower-type operating mode: 63 metre main boom plus 36 m tower and super lift jibs.
To further test the QAY 1200, a cup of water was placed on the body of the QY 160K. The larger crane then lifted the smaller one 80 m in the air, swung it through 45 degrees and lowered it back to the ground. The cup of water remained full.
