Hiyo HY245H-S Excavator
Product Overview
HY245H-S is a 25.5-ton heavy-duty mining hydraulic excavator independently developed by Hiyo Heavy Industry, which won China Construction Machinery TOP50 Golden Finger Award for outstanding heavy-load performance. This National IV upgraded machine adopts new power, brand-new appearance and HOPE intelligent electro-hydraulic technology, tailored for medium and small mine harsh working conditions. It weighs 25500kg with 1.4–1.55m optional bucket capacity, delivering powerful breakout force to handle rock stripping, mass earthmoving, foundation excavation, municipal renovation and landscaping projects. Optimized positive flow hydraulic system cuts fuel consumption by 10%, while reinforced impact-resistant frame extends service life under quarry and mine sites. All technical parameters shall be subject to physical delivered machines due to continuous technical iteration.
HOCT Energy-Saving Hydraulic & Mine Reinforced Design
Hiyo HY245H-S 25.5-ton heavy excavator integrates exclusive HOCT self-optimization hydraulic control and mine-strengthened structure, balancing powerful mining performance and low fuel expenditure. Matched with 150kW National IV high-torque engine and Kawasaki full electric control pump, the machine dynamically adjusts hydraulic flow according to digging resistance to eliminate power waste, saving 10% fuel compared to similar 25-ton models. Dual 1.4/1.55m³ bucket options support switching between large-volume earthmoving and hard rock mining without replacing extra attachments. All boom, arm and chassis adopt thickened high-strength steel with anti-impact structure, passing long-hour quarry durability tests. The 3800mm minimum turning radius solves space restrictions in urban municipal trenches and small mine tunnels. Upgraded cabin air conditioning reduces operator fatigue during all-day mining shifts. Suitable for mine, stone, foundation and landscaping projects, HY245H-S delivers stable high output with long-term low maintenance cost.
Key Highlight Features
- National IV high-power engine: 150kW/2000rpm rated output, large torque reserve, DOC+DPF+SCR aftertreatment, stable heavy-duty power supply.
- Kawasaki full electric control positive flow hydraulic system: Matched exclusive HOCT self-optimization tech, reduce energy loss and boost composite operation smoothness.
- Ultra-strong digging capacity: Max bucket breakout force 187kN, arm breakout force 129kN, optional rock bucket for hard ore and stone breaking.
- Dual bucket configuration: Standard 1.4m³ earth bucket, optional 1.55m³ large bucket, realize one bucket matching one working condition.
- Mine-strengthened structural design: 30T anti-impact frame, thickened boom and arm, high-strength wear-resistant steel for long quarry service life.
- Compact swing layout: 3105mm tail swing radius and 3800mm minimum turning radius, flexible in narrow mine roadways and urban trenches.
- Premium wide-view cabin: Optimized shock absorption and air conditioning, rear camera equipped to improve construction safety.
- Excellent terrain passing: 454mm minimum ground clearance, 70% (35°) climbing capacity, stable on slippery mine slopes.
- Wide multi-scenario compatibility: Covers mine, stone, earthwork, housing foundation, municipal and landscaping engineering.
Performance Advantages
- Outstanding energy-saving effect: HOCT dynamic load matching hydraulic system reduces overall fuel consumption by 10% vs ordinary medium excavators.
- Super heavy-duty excavation: Peak 187kN bucket breakout force easily crushes hard rock and complete large-volume ore stockpile loading.
- Stable all-terrain traveling: 5.8/3.7km high/low travel speed, 52.5kPa low ground pressure, prevent sinking on muddy mine ground.
- Smooth rotary performance: 10rpm steady swing speed without jitter during continuous mass mucking inside tunnels and mines.
- Large operation coverage: Max digging depth 6690mm, max digging radius 10225mm, meet deep foundation and long-distance material transport demands.
- Ultra-long service cycle: Mine reinforced structural parts pass thousands of hours quarry durability tests, cut spare parts replacement frequency.
- Low overall maintenance cost: Large-capacity fuel and urea tanks, extended maintenance intervals, less downtime for mining fleets.
- Narrow space adaptability: Small tail swing avoids wall collision in underground mine tunnels and downtown narrow construction roads.
- Multi-purpose flexibility: Switchable bucket attachments freely convert between mining, earthmoving and landscaping construction tasks.
