2. Key Performance Features

2.1 High-Efficiency Power & Hydraulic System

The self-developed SAA6D107E-1 engine adopts high-pressure common rail fuel injection technology and ECU intelligent control, delivering 10% lower fuel consumption than the previous PC210-7 series while ensuring sufficient power output.
Equipped with Komatsu's proprietary CLSS (Closed-center Load Sensing System) and HydrauMind hydraulic control technology, it supports smooth compound movements (digging, swinging, traveling at the same time) with minimal hydraulic loss, greatly improving operation precision and efficiency.
4 optional working modes: P mode (heavy-load high efficiency), E mode (energy-saving for general works), L mode (fine operation for land leveling, pipe laying), and attachment mode (for breaker, grapple etc.), adapting to different working scenarios.

2.2 Extreme Structural Durability

The boom, arm and bucket are made of high-tensile steel, with stress relief treatment at all welding positions, resisting impact and deformation under long-term heavy-load conditions.
The reinforced undercarriage adopts sealed and lubricated track rollers, carrier rollers and idlers, extending service life by 30% compared with ordinary models. Track shoes can be customized with wear-resistant versions for quarry and mining scenarios.
The integral welded frame has excellent torsion resistance, suitable for rugged construction sites. All pins of the working device are equipped with dust-proof seals, reducing wear and extending maintenance intervals.

3. Operator Comfort & Safety

The cabin meets international ROPS (Roll-over Protective Structure) and FOPS (Falling Object Protective Structure) certification, ensuring personal safety in case of rollover or falling objects.
The suspension-type cabin base reduces vibration by more than 20%, and the indoor operating noise is as low as 72 dB(A), creating a quiet working environment.
The multi-adjustable air suspension seat, ergonomic low-force pilot control joystick, and adjustable armrest greatly reduce fatigue during long hours of operation.
The full-color LCD monitor displays real-time data such as fuel consumption, water temperature, hydraulic oil temperature, and fault codes, supporting multi-language switching. Standard travel alarm, swing alarm and optional reverse camera further improve operation safety.

4. Environmental & Maintenance Advantages

The engine meets EPA Tier 3 / EU Stage 3A / China Stage III emission standards, with cooled EGR technology to reduce NOx emissions, no black smoke during operation.
All daily maintenance points (fuel filter, oil filter, hydraulic oil filter, etc.) are arranged at ground-accessible positions, reducing daily inspection time by 40%.
Long maintenance intervals: engine oil replacement every 500 working hours, hydraulic oil replacement every 5000 working hours, greatly reducing operation costs.
Equipped with Komatsu's exclusive KOMTRAX remote monitoring system, supporting real-time tracking of equipment location, working hours, fuel consumption and fault warning, which is convenient for fleet management and anti-theft.

5. Application Scenarios

The PC210-8 is widely used in:

Municipal engineering: road construction, trench digging, pipeline laying
Civil construction: foundation excavation, earthwork transfer
Mining and quarry: surface soil stripping, sand and gravel loading
Water conservancy and agriculture: river dredging, reservoir renovation, tree planting hole digging
Special operations: concrete breaking (with breaker), wood/grabage handling (with grapple), building demolition (with hydraulic shear)

With high market retention, stable performance and high second-hand residual value, the PC210-8 is recognized as a benchmark model in the 20-ton excavator segment.
