Original HItachi ZX80 Compact Crawl Excavator 0.28m3 Bucket Capacity Used Excavator

Used Hitachi ZX80 Crawl Excavator 0.28m³ Bucket Capacity Compact Used Excavator

This model is equipped with a high-power power system and a 39-kilowatt high-efficiency engine, which can maintain stable output at 2100 rpm. Innovative energy-saving technology significantly reduces fuel consumption, saving more than 15% of energy expenditure for engineering projects. By optimizing the hydraulic circuit design, the equipment has achieved dual performance improvements: the operating speed is increased by 20%, while the control accuracy reaches the industry-leading level of ±2 mm. Its intelligent hydraulic drive system integrates a number of patented technologies, including dynamic flow distribution valves and pressure compensation pumps to ensure that the continuity of movement is optimal.

The equipment, equipped with a 0.28 cubic meter standard bucket, has multi-scenario construction adaptability. Actual measured data shows that in typical working conditions such as earth excavation and site leveling, its operating efficiency is 12% higher than that of similar products. The specially designed extended arm structure extends the excavation radius to 5.8 meters and the maximum excavation depth exceeds 3.2 meters, which can meet the construction requirements of most municipal and construction projects. The mechatronic control system is equipped with a 7-inch color touch screen, which supports switching between three operating modes, significantly reducing the complexity of operation.

The reinforced chassis with box-section design has a 30% increase in torsional rigidity after finite element analysis and optimization. The four-wheel one-belt system is equipped with an automatic tensioning device, which can still maintain excellent stability when operating on slopes. Its slewing mechanism is equipped with a high-precision reducer with a starting torque of 25kN·m and a positioning error controlled within 0.5°. The key articulated parts are all chrome-plated pins, combined with self-lubricating bearings, which effectively extend the maintenance cycle to 2000 hours.

Adopting Isuzu CC-4JG1 engine with rated power of 39kW/2100rpm and displacement of 3.1L, it has a strong power output and can meet the demands of high loads and harsh working conditions, such as stable operation in complex environments such as mines and large-scale construction projects.

Equipped with advanced hydraulic system, the maximum flow rate of the main pump is 126l/min, adopting Kawasaki hydraulic pump and other high-quality hydraulic components, which makes the excavator's action respond quickly and accurately, with excellent digging and gripping force, improving work efficiency and quality, and precisely controlling the digging depth and angle.

The engine and hydraulic system are well matched and work stably together to maintain stable power output under different working conditions, avoiding power interruptions or fluctuations, ensuring smooth excavation operations and prolonging the service life of the equipment.

High combustion efficiency of the engine, combined with the advanced hydraulic system, can reasonably distribute power, reduce fuel consumption, save costs, and have obvious advantages in long-term large-scale operations.
The components of the power system are made of high quality materials and advanced manufacturing technology, with reliable quality and strong durability, and have been strictly tested and verified, which can adapt to a variety of complex working conditions, reduce the downtime and improve the equipment attendance rate.

The layout of the engine and hydraulic system is reasonable, the parts are easy to check, repair and replace, and the daily maintenance is simple and convenient, which reduces the maintenance cost and difficulty, shortens the maintenance time and improves the efficiency of the equipment.
