Sany (SAC12000) overrun hoisting experiment - global limit hoisting capacity of 850 tons (arm length 32.lm, working amplitude 4.2m)

Case Description: In order to test the lifting capacity of the SAC12000 in an all-round way, Sany Crane Research Institute has implemented a series of overrun hoisting experiments, among which the global limit lifting capacity of 850 tons is particularly interesting. Construction time: July 17, 2011 Experimental requirements: SAC12000 Under the amplitude of 4.2 meters, the maximum lifting capacity of the main boom is 850 tons. Construction difficulties: the main boom directly lifts 500 tons, and no all-ground manufacturer in the world has conducted experiments. Equipment selection: Sany SAC12000 Construction process: Under the arm length of 32.l meters and the working amplitude of 4.2 meters, the pallet weighing 850 tons was lifted quietly and gently off the ground by SAC12000. The main arm, turntable, frame and other structural parts did not appear deformed, cracked base metal, cracked welds, peeled paint, loose connections and other phenomena, the electrical and hydraulic systems worked normally, and the measurement data met the design standards.
