Performance Advantages

Strong Mining Power: Bucket digging force 287kN, arm digging force 245kN, easily break hard rock and dense soil.

Lower Operation Cost: ACE hydraulic control reduces pressure loss; SCR precise fuel control cuts overall fuel consumption.

High Site Adaptability: 35° gradeability, 80.42kPa ground pressure, works steadily on muddy, rocky and sloped mine ground.

High Working Efficiency: Optional 3.1m³ oversized bucket boosts loading volume per cycle, shortening construction cycle time.

Intelligent & Safe Operation: Integrated intelligent monitoring system, real-time fault alarm, FOPS/ROPS protective cabin improves operator safety.

Long Service Life: Reinforced bucket wear plate, heavy-duty track and optimized powertrain reduce maintenance frequency.

Hiyo HY485H-S large mining excavator is a 48.5-ton heavy-duty crawler digger designed for open-pit mines and massive earth-rock projects. Powered by original Isuzu 6WG1 diesel engine with 310kW rated power, it delivers steady high torque under heavy loads to tackle hard rock excavation and bulk material loading. Its upgraded ACE semi-electronic hydraulic system matches KMX32NA multi-way valve, lowering hydraulic loss to save fuel while lifting digging force up to 287kN for the bucket. Complying with China National IV emission standard via SCR exhaust treatment, it cuts NOx and particulate pollution without sacrificing power. The machine supports four interchangeable buckets, from standard 2.6m³ rock bucket to optional 3.1m³ high-capacity bucket, adapting to rock mining, soil stripping and stone transportation. The spacious C12 intelligent cabin equips a 10-inch touch screen with one-key startup and remote fault diagnosis, greatly improving operation comfort and maintenance efficiency. With 35° climbing ability and reinforced track components, HY485H-S runs reliably on rough mine slopes, reducing downtime and raising overall project profit for mining enterprises.

Hiyo Intelligent Production Workshop – Strict Manufacturing for Mining Excavators

Hiyo’s heavy machinery intelligent workshop adopts full digital production lines for manufacturing HY485H-S large excavators. Every component including engine, hydraulic valve and track frame goes through multi-process precision machining and quality inspection. The workshop implements unified heavy-duty production standards for mining equipment, with reinforced welding and wear-resistant surface treatment for bucket and arm structures. Automated assembly stations reduce manual error and improve machine consistency. All finished HY485H-S excavators undergo full-load running tests, simulating mine climbing, rock digging and long-hour continuous operation to eliminate hidden defects. Strict workshop quality control ensures each machine matches official technical parameters, delivering durable, reliable mining diggers with long service life for global mining investors.
