The Full Electronic Variable-speed Engine Can Better Make Full Use of Fuel

The product is equipped with a rare full electronic variable-speed engine of the same tonnage to realize synchronous control. Compared with the mechanical speed regulation, it can make full use of fuel, reduce fuel consumption substantially while ensuring the operation volume, and show excellent fuel efciency among products of the same tonnage. Exhaust emission complies with China's Stage III Emission Standard.

Routine Maintenance Convenient, Saving Time, Labor, and Cost

The parts for routine maintenance and inspection are reasonably laid out, which improves the maintenance efciency. Hitachis pure high performance hydraulic oil lter is adopted, with its replacement cycle of 1000 hours and the hydraulic oil replacement cycle of 3000 hours. The rotary reducer is lubricated by hydraulic oil, so there is no need to change lubricating oil or check the oil quantity of the rotary reducer every day.

High-end Quality of Core Parts

The engine, pump, valve, motor and other core components inherit the consistent high-end quality of Hitachi's products, improving durability and value preservation.

Reliable and Durable Structural Design

The upper revolving frame adopts the D-shape section rack, which improves the strength of resisting external impact. The X-beam of the lower walking body is designed in an integrated welding structure, which improves the dropping strength and stability. A reinforcing plate is installed on the bucket rod, a wear plate is installed on the bucket bottom, and the boom cylinder employs a strong cover plate for protection. More reliable designs not only extend the service life of the product, but also add more value to the product
