Designed for durability – an optimised FEM analysis was used to overhaul the entire excavator structure. This resulted in a considerable reduction in stress concentrations and an extension of the components exposed to the most stress – for example, the boom was extended by 30% and the bucket arm increased by 65%. The means that the new SANY mini excavator is optimally equipped for tough everyday work – once again being a cut above the rest with its service life extended by 30% on average.
