When selecting a heavy-duty loader, you must prioritize the Rated Load Capacity (typically ranging from 3 to 10 tons for heavy-duty models) and the Engine Power, ensuring it meets international standards like Cummins or Weichai for reliability. Pay close attention to the Hydraulic System pressure and Cycle Time (lifting, dumping, and lowering), as these directly impact operational efficiency. Additionally, verify the Bucket Capacity (m³) matches your specific material density to prevent premature wear on the Transmission System.
