Features, Functions, and Advantages of the Komatsu PC70 Crawler Excavator

Engine & Fuel-Efficient, Environmentally Friendly Performance

• The new Komatsu SAA4D95LE-5 engine is compact and lightweight, yet delivers a powerful output of 48.5 kW (65 HP). Equipped with a turbocharger, it ensures stable performance even at high altitudes

• Fuel consumption is optimized through the integrated control of the engine, hydraulic system, and electronic system.

• Complies with U.S. EPA Tier 3 and EU Stage 3A emission standards, significantly reducing NOx while maintaining high productivity.

• The ECO Gauge displayed on the LCD monitor assists in energy-efficient operation and helps reduce CO₂ emissions.

• Flexible Working Modes:

  • P-Mode (Power): Prioritizes maximum power and operating speed.

  • E-Mode (Economy): Focuses on fuel savings, ideal for light-duty operations. Adjustable between E0/E1 levels for different degrees of fuel efficiency.

• Auto-deceleration & Idle Warning: Helps minimize fuel consumption when the machine is not in operation.

• CLSS Hydraulic System (Closed-center Load Sensing System): Combines power and precision, enabling smooth control and improving work efficiency.

Modern Operator’s Cabin

• Spacious, Noise-Reduced Cabin: Rigid frame with excellent sound insulation, minimizing noise from the engine, hydraulic system, and air conditioning

• All-round Visibility: Wide windows and an adjustable sliding/reclining seat provide comfort during long working hours.

Applications of the Komatsu PC70 Crawler Excavator

• Civil Construction Applications:

  • Excavating foundations for houses and small to medium-sized structures.

  • Trenching for water supply and drainage pipes, electrical conduits, and sewer systems.

  • Site clearing, earth grading, land leveling, and soil improvement.

• Transportation Infrastructure – Roads and Bridges:

  • Constructing small roads, village roads, and internal roads within industrial zones.

  • Building access roads and branch roads.

  • Executing bridge works, embankments, and roadside drainage ditches.

• Urban Projects and Confined Spaces:

  • Operating in residential areas, narrow roads, and restricted access sites.

  • Compact design with crawler tracks enables work on soft ground or gentle slopes.

  • Repairing sewer/drainage systems in city streets, and replacing gas, power, and water pipelines.

• Earthmoving and Small-Scale Mining:

  • Excavating and handling soil or small rocks in quarries or small-scale mining operations.

  • With relatively strong breakout force for its size, the machine is well-suited for digging through rocks, removing small stumps, and working on mildly rugged terrain.

• Demolition and Small-Scale Reconstruction:

  • When equipped with concrete breakers or hydraulic hammers, it can demolish concrete floors and small structures.

  • With a pulverizer bucket, it can efficiently process concrete and small walls.

• Versatile Rental and Service Work:
  • With its compact-medium size, the machine is easy to transport and widely used in construction equipment rental fleets.
  • Ideal for temporary works, small-scale projects, and civil construction jobs.
