Komatsu PC350-8 Crawler Excavator Detailed Introduction

The Komatsu PC350-8 is a 35-ton class medium-to-heavy crawler excavator developed and manufactured by Komatsu Ltd., the Japan-based global leading construction equipment manufacturer. As a core product of Komatsu’s 8-series excavator lineup, it balances high operating efficiency, low fuel consumption, extreme durability and operator comfort, and is widely applied in infrastructure construction, mining, quarrying, municipal engineering and other heavy-load scenarios.

Key Performance Advantages

1. High-Efficiency & Low-Consumption Powertrain

The SAA6D114E-3 engine adopts Komatsu’s proprietary electronic high-pressure common rail fuel injection technology, delivering 5-10% lower fuel consumption than the previous 7-series PC350 under the same operating conditions. It supports 3 customizable working modes:

Power (P) mode: for heavy-load excavation and rock breaking scenarios to maximize operation efficiency
Economy (E) mode: for light-load site leveling and loading scenarios to reduce fuel cost
Lifting (L) mode: for heavy object hoisting operations to ensure stable power outputThe engine also has strong environmental adaptability, and can work stably at altitudes up to 4,000m and ambient temperatures up to 45℃ without obvious power attenuation.

2. Precision Hydraulic System

The PC350-8 is equipped with Komatsu’s exclusive Closed-center Load Sensing System (CLSS), which precisely matches hydraulic flow output with actual operation demand, effectively reducing hydraulic loss and improving operation accuracy. Pressure compensation valves are installed for each actuator, ensuring smooth and coordinated compound actions (e.g. simultaneous boom lifting + arm retracting + upper structure swing), with comprehensive operation efficiency 8% higher than similar products of the same tonnage. All core hydraulic components (main pump, main valve, travel/swing motor) are original Komatsu parts, with optimized sealing design to greatly reduce leakage risk.

3. Heavy-Duty Structural Durability

The whole machine is designed for long-term heavy load conditions:

Boom, arm and bucket are made of high-strength alloy steel, key stress positions adopt robotic welding and thickened plate reinforcement to resist impact load in mining and quarrying operations
X-shaped undercarriage has excellent torsional resistance, track chain, supporting rollers and idlers are all surface-hardened, with service life 20% longer than the previous generation
Standard heavy-duty bucket is fitted with wear-resistant tooth plates, adapting to hard rock excavation and other harsh working conditions

4. Safe & Comfortable Operating Experience

The cab meets ROPS (Roll-over Protective Structure) and FOPS (Falling Object Protective Structure) safety certification, effectively protecting operators in case of rollover or falling object impact:

Fully adjustable viscous damping seat reduces vibration transmission by 30% compared with ordinary seats
Cab internal noise is controlled below 75 dB(A), leading the same tonnage segment
7-inch high-definition LCD monitor displays real-time parameters including engine status, hydraulic pressure, fuel level and fault warnings
Low-force operation joystick and multi-outlet high-performance air conditioning system greatly reduce long-time operation fatigue

5. Convenient Maintenance & Intelligent Management

All routine maintenance points (engine oil dipstick, oil filter, fuel filter, air filter, hydraulic oil filter) are arranged at ground-accessible positions, no need to climb the upper frame for daily inspection. The cooling system is equipped with a self-cleaning reverse fan, which automatically blows off dust and debris on the radiator surface to reduce manual cleaning frequency.It is also fitted with Komatsu’s exclusive KOMTRAX remote monitoring system, which transmits real-time equipment operation data, location, fuel consumption and fault information to managers, supporting predictive maintenance and reducing unplanned downtime by more than 15%.

Optional Configurations

Hydraulic breaker pipeline and quick coupler for attachment switch
Extended boom/arm for deep excavation and high dumping scenarios
Wide track shoes for soft soil and swamp working conditions
Cold zone upgrade package for -30℃ low temperature operation
Wear-resistant rock bucket for hard rock mining scenarios

Typical Application Scenarios

Infrastructure construction: foundation pit excavation, road subgrade construction, water conservancy project construction
Mining and quarrying: surface overburden stripping, ore excavation and loading, stone handling
Municipal engineering: old building demolition, site leveling, pipeline trench excavation
Port logistics: bulk cargo loading and unloading, yard material sorting

Non flooded

No accident
