Changchun, 22 April, 2009 - Sonus, a leading engineering firm in China, successfully completed a stain gauge testing on a mining truck’s radiator.

Contracted by Terex Corporation, Sonus conducted a strain gage testing on the MT4400 at the Haerwusu open-pit coal mine to determine the maximum principle stress on the radiator under working conditions of the truck. The rainflow counting method has been applied for the strain gauge signals. Acceleration has been measured as well during the strain gauge testing.

Measuring 14.1m×8.0m×7.1m, the MT4400 is one of the world’s largest trucks, the size and volume of which added to the complexity of the testing process.
