日立建機 ZX 120

Powerful, efficient, and reliable: Equipped with an Isuzu engine, which is one of the core advantages of this model, it not only provides stable power output but also features an intercooler with excellent combustion efficiency, achieving a balance between power and fuel economy while reducing long-term operational fuel costs. The use of direct injection technology further enhances fuel utilisation, making it suitable for extended continuous operation. Durable hydraulics and structure: The HIOSⅡ hydraulic system allows precise control of engine speed, combined with high-performance main pumps and motors to ensure efficient and smooth hydraulic transmission with responsive operation. Structurally, the boom and arm are reinforced with thicker steel plates, the side doors use closed-section stiffeners, and the reinforced rotating main platform significantly enhances the overall durability and operational stability of the machine, capable of withstanding complex working conditions. Safe and comfortable operation: The cab is reinforced with a CRES central pillar structure to improve overall strength and rigidity, providing a solid safety barrier for the operator. The cab’s ergonomic design ensures comfort during long working hours, reducing operator fatigue. Applicable scenarios and market performance: As Hitachi's flagship model under 20 tonnes, it is suitable for various applications such as construction, road building, and small-scale mining. The model is well-known and holds a high market share due to its stable performance and low failure rate, resulting in high user satisfaction. Its second-hand equipment also retains considerable value. However, this model has been discontinued, and most units available are second-hand. Regular maintenance, including oil changes and inspections of the tracks and boom, is required to ensure stable operation.
