The Hitachi ZX490LCH-5G excavator has a number of structural design advantages. It uses thickened steel plates to create an integrated rocker arm, which enhances structural stability and deadweight, thereby improving digging force. The arm cylinder is removed from the rocker arm, which increases the digging depth and reduces maintenance costs. In addition, the hydraulic layout is optimized, the hydraulic flow is concentrated, and the advantages of dual pump confluence are fully utilized to improve work efficiency. After rigorous testing, the design also fully considers practical issues such as transportation to ensure a high-quality production process.
The Hitachi ZX490LCH-5G excavator is equipped with an Isuzu engine, which has strong and stable power output and can easily cope with complex working conditions. In addition, it also has the characteristics of fuel saving and high efficiency, while maintaining high operating efficiency, reducing fuel consumption and reducing operating costs.
The Hitachi ZX490LCH-5G excavator enjoys a high reputation in the large excavator market and occupies a considerable market share. Isuzu engines are known for their versatility, easy repair and low maintenance costs, and spare parts are in sufficient supply. In addition, second-hand engines depreciate slowly and have high residual value, making them a reliable investment.
