Sany has displayed the 220 tonnes all terrain, QAY220, during 2009 Shanghai Bauma. It was the prototype of its first all-terrain crane developed under the Sany brand. Unlike rivals manufacturers Zoomlion and XCMG, their QAY220 is built on a five-axle chassis instead of a six-axle chassis.
The crane comes with a six-section, 62 metres main boom and can reach a maximum lifting height of 105 metres when the luffing jib is being used. It runs on a Hydac hydraulic suspension and Kessler axles and has a low-speed turning radius of fewer than 20 metres. The carrier’s uses imported Benz OM502LA.E3A (390 kW/1800 rpm) transfers power through a ZF AS-Tronic gearbox. The 15.8 metres long crane weights 60 tonnes (without counterweight). [irp]
