HY335BH-S Crawler Excavator

Fuel-Saving & High-Efficiency Hydraulic Optimization

Hiyo HY335BH-S stands out among 33-ton class diggers with dual optimization of main pump control curve and bucket structure, realizing simultaneous efficiency boost and fuel reduction. The upgraded hydraulic coordination algorithm eliminates power waste during compound digging and dumping actions, matching perfectly with Isuzu high-torque engine to cut hourly fuel cost. Users can freely switch between 1.65m standard and 2.0m large buckets for light soil and heavy aggregate quarry tasks. 540mm high ground clearance and wide track shoes avoid sinking on soft construction soil. The 3237mm short tail swing avoids wall collision in confined underground tunnel spaces. Extended lubrication and filter replacement intervals lower daily maintenance expenditure. With balanced performance and low running cost, HY335BH-S becomes the mainstream earthwork flagship for infrastructure and rental enterprises globally.

Multi-Scenario All-Round Construction Digger

Hiyo HY335BH-S 32.5-ton medium heavy excavator breaks single earthwork machine limitation, covering five core construction fields: mass earthmoving, stone quarry, open-pit mine, railway tunnel and aggregate processing. Its optional 2.0m large bucket greatly shortens bulk material loading cycles, while 218kN breakout force handles medium-hard rock stripping smoothly. National IV low-emission engine meets strict environmental rules in suburban construction zones. Max digging depth 6571mm fully satisfies roadbed and residential deep foundation excavation demands. Every finished machine undergoes continuous heavy-load earth simulation running tests before delivery to guarantee stable hydraulic and power performance. Compact swing design adapts both open earth yards and narrow underground roadways. As Hiyo’s star earth-specialized model, it maintains steady global bulk orders from construction and mineral groups.

Key Highlight Features

1. National IV Isuzu 6HK1 engine: 210kW/1900rpm rated power, large torque reserve, low fuel consumption under long-hour earthwork.
2. Short arm large bucket configuration: Short working arm matched with max 2.0m bucket, higher digging stroke and faster loading cycle.
3. Optimized main pump control curve: Reduce hydraulic power loss, realize balance of efficiency and fuel saving.
4. Upgraded bucket profile: Reshaped bucket inner wall to improve material filling rate and reduce residual soil.
5. Improved hydraulic coordination algorithm: Smoother compound movement of digging, lifting and dumping.
6. Multi-size interchangeable buckets: 1.65m standard earth bucket / optional 2.0m large bucket for diversified working conditions.
7. Stable heavy-duty chassis: 600mm wide track shoe, 540mm ground clearance, 70% climbing capacity.
8. Compact tail swing layout: 3237mm tail radius, flexible in narrow tunnel and municipal trenches.
9. Wide application coverage: Earthwork, stone quarry, open mine, railway & tunnel construction, aggregate processing.

Performance Advantages

1. Dual core breakthrough: Optimized pump curve + reshaped bucket cut fuel consumption while lifting overall productivity over 10%.
2. Powerful digging output: 218kN bucket breakout force, fast full-bucket loading for large-volume earth stockpiles.
3. Smooth compound action: Updated hydraulic coordination avoids pause during continuous digging and transportation.
4. Flexible multi-condition switching: Swap 1.65m and 2.0m buckets without extra attachment investment.
5. Excellent terrain adaptability: 35° climbing angle, low 60.3kPa ground pressure prevents sinking on soft soil.
6. Large working range: Max digging depth 6571mm, fit deep foundation and roadbed excavation tasks.
7. Compact turning design: 4000mm minimum radius works well in narrow tunnel inner spaces.
8. Low daily operation cost: Engine and hydraulic parts have extended maintenance intervals to cut downtime loss.
9. Long structural service life: Thickened boom and arm resist abrasion in long-term earth & stone jobs.
