•Power configuration: Diesel engines with reasonable power and superior performance provide a powerful source of power for construction operations, and the reliability of power and fuel economy have been greatly improved. •Hydraulic system: Advanced hydraulic system, high-quality hydraulic components, and strict assembly process ensure the high efficiency and durability of the hydraulic system. •Design: The overall frame structure is excellent, and the materials are completely national standard. High strength and good stability, in line with the design idea of industrial aesthetics, and the operator's working space is more spacious. •Production Process: The production process is more reasonable, and the wear-resistant parts are all heat-treated. The welding process is rigorous; the overall stress relief treatment of frame welding reduces deformation, and the testing equipment is perfect
