Used Hyundai 350LVS Excavator for Sale | 33 Ton Crawler | Competitive Price & Full Specs

The Hyundai 350LVS is powered by the HYUNDAI HE8.9 engine – a 6‑cylinder, 4‑stroke, water‑cooled turbocharged diesel with 8.9L displacement.

Its core advantage is high‑pressure common‑rail electronic fuel injection, which ensures more complete combustion, delivering strong power with lower fuel burn.

• Rated power: 221 kW @ 1,850 rpm (~296 hp)

• Max torque: 148 kgf·m @ 1,400 rpm

• Fuel efficiency: With the IPC (Intelligent Pump Control) / VPC system, fuel savings are 10–15% compared to conventional models. The system adjusts main pump flow based on joystick input, matching power to the work mode.

Bottom line: 221 kW gives ample power reserve, while common‑rail technology keeps fuel consumption low for a 35‑ton class machine.

While Hyundai does not officially expand the acronym, in industry terms:

• L usually means Long or Heavy‑Duty (reinforced)

• VS likely indicates Versatile or a specific series code.

The 350LVS is designed as a heavy‑duty 35‑ton excavator for both earthmoving and rock work.

• Boom & arm: Reinforced cast steel at key stress points – service life increased by 1.5×.

• Undercarriage: Swing circle base plate thickened; welding strength of the lower frame increased by 20%.

• Key structural data:

  • Operating weight: 33,200 kg

  • Bucket capacity: 1.60 m³ (general purpose / rock bucket optional)

  • Track shoes (per side): 48; track rollers: 9

Conclusion: The 350LVS is heavier (33.2t) than previous models and built with mining‑grade reinforcement – truly a quarry‑ready machine.

The Hyundai 350LVS is optimised for fast cycle times and smooth combined movements. The main control valve oil circuit design has been improved to boost truck loading productivity.

Speed data:

• Swing speed: 9.8 rpm – smooth start/stop, ideal for frequent truck loading.

• Travel speed: 6.3 / 3.5 km/h (high/low) – fast job‑site mobility, 70% gradeability.

Yes. The 350LVS is built for heavy attachments (rock breaking, deep digging). It features a high‑output hydraulic system.

• Pump type: Two variable‑displacement piston pumps

• Main pump flow: 2 × 315 L/min (total 630 L/min)

  • *Note: Some sources show a lower figure (2×135 L/min) – likely due to different measurement standards or dual pressure settings. The 630 L/min figure is widely cited for the 350LVS in heavy‑duty configurations.*

• This flow easily supports a 195‑class hydraulic hammer, delivering consistent blow frequency and power.

• Additional features:

  • Standard hammer piping (factory option – check specific unit)

  • Attachment management system allows preset flow and pressure for breaker, shears, or compactor.

Based on field data and owner reports (combined with Hyundai’s fuel‑saving tech):

• Typical fuel consumption (digging/loading): 21–25 L/hour
  (compared to older 35‑ton models that often burn 28–32 L/h)

• With hammer work: ~26–30 L/h depending on material hardness

Maintenance intervals:

• Engine oil & filter: 500 hours

• Hydraulic oil filter: 1,000 hours

• Hydraulic oil change: 5,000 hours (factory recommendation, but test oil quality every 2,500 hours in dusty conditions)

• Swing & travel gear oil: 2,000 hours

Service convenience:

• Grouped service points (all filters and dipsticks accessible from ground level)

• Automatic greasing system (optional, but recommended for heavy use)

Key takeaway: The 350LVS delivers class‑leading fuel economy (21–25 L/h) while maintaining high productivity – a major cost saver over 10,000 operating hours.
