2. DOMCS intelligent dynamic matching system: Real-time coordination of engine, pump and valve, cut power waste and boost overall efficiency by 8%.
3. Optimized positive flow hydraulics: Low pressure loss main valve, smooth composite digging, loading and leveling actions.
4. Dual interchangeable buckets: Standard 1.9m earth bucket, optional 2.15m rock bucket to match light soil and hard mine stone tasks.
5. Ultra-reinforced mine structure: All load-bearing components adopt thick high-strength steel, pass thousands of hours quarry abrasion tests.
6. Stable heavy chassis: 600mm wide track shoes, 9 track rollers per side, 68.8kPa low ground pressure to avoid sinking on mine mud.
7. Premium shock-absorbing cabin: Wide panoramic view, upgraded air conditioning, reduce operator fatigue during all-day mining shifts.
8. Strong terrain adaptability: 70% (35°) climbing capacity, suitable for mine slopes, quarries and large foundation sites.
9. Multi-scenario compatibility: Fully fit open-pit mine, stone quarry, mass earthwork and infrastructure foundation projects.

Performance Advantages

1. Super digging power: 235kN bucket force & 230kN arm breakout force, fast loading cycles to raise mine hourly output greatly.
2. Balanced fuel & efficiency: DOMCS intelligent matching cuts fuel consumption by 10% vs same-class 38-ton mining excavators.
3. Stable traveling performance: Max travel speed 5.0km/h, low speed 3.0km/h, steady movement on slippery mine ramps.
4. Smooth rotary operation: 9.2rpm constant swing speed, no jitter during continuous ore stockpile loading.
5. Large working coverage: Max digging depth 7155mm, max digging radius 10750mm, meet deep foundation and high stockpile demands.
6. Ultra-long maintenance interval: Long-life engine oil and filter, cut spare part replacement frequency by half.
7. Low failure hydraulic system: Multi-stage oil filtration prevents impurity abrasion for long-term mining work.
8. High structural durability: Key parts adopt full forging process, service life doubled compared ordinary medium heavy diggers.
9. Flexible bucket switching: Fast replacement between earth and rock bucket without extra attachment investment.

DOMCS Energy-Saving Intelligent Hydraulic Tech

Hiyo HY375H-S stands out among 38-ton mining excavators with exclusive DOMCS engine-pump-valve coordinated control technology. The system automatically adjusts power output according to digging resistance, eliminating useless power loss and realizing 10% fuel reduction without sacrificing digging force. Matched with reliable Isuzu 210kW National IV engine, it supplies stable high torque for thick rock layer excavation. Users can switch 1.9m earth bucket and 2.15m rock bucket freely to cover soft soil and heavy stone construction. All key structural components adopt full forging craft, doubling service life compared with ordinary heavy excavators. Multi-stage hydraulic filtration system avoids oil contamination under long quarry operation. The 4120mm minimum turning radius solves space limitation in small mine pits and urban foundation trenches. Low maintenance frequency and high hourly output make HY375H-S the most cost-effective mining workhorse for medium mineral enterprises.

Multi-Scenario Versatile Heavy Excavator

Hiyo HY375H-S 38.9-ton heavy crawler excavator breaks single mining machine limitation, covering four core construction fields: open-pit mine, stone quarry, large mass earthwork and infrastructure foundation engineering. Its 235kN powerful digging force and optional oversized bucket greatly raise daily loading volume for mineral projects. National IV low-emission engine meets strict environmental control rules in mining zones and suburban construction areas. Max digging depth 7155mm fully satisfies deep foundation excavation for large infrastructure projects. Every finished HY375H-S undergoes continuous heavy-load running tests to verify engine and hydraulic stability before delivery. Compact swing design ensures flexible operation both underground mine roadways and urban narrow sites. As Hiyo gold award flagship heavy machine, it maintains steady bulk orders and positive feedback from global mining and construction groups.
