The Komatsu PC60-8 is a well-regarded hydraulic excavator known for its performance and reliability, making it a popular choice in construction and excavation projects. This 2016 model, which has worked for 9,800 hours, offers a blend of efficiency, robust power, and versatility, making it suited for a variety of tasks including digging, lifting, and earthmoving. Below is a detailed analysis of its specifications, performance, and technical features.
Engine and Power System
At the heart of the PC60-8 is the Komatsu SAA4D95LE-5 engine, which delivers a rated power output of 40.7 kW at 1,950 rpm. This four-cylinder engine features a turbocharged design, enhancing its performance, particularly in demanding applications. The engine is water-cooled and has a displacement of 3.26 liters, ensuring efficient fuel consumption while maintaining the necessary power output for the machine’s operational requirements. With a bore and stroke of 95 mm × 115 mm, this engine is designed for durability and consistent performance in tough environments.
Hydraulic System
The hydraulic system of the Komatsu PC60-8 is designed to provide smooth and efficient operation, which is crucial for its digging and lifting capabilities. The variable displacement piston pump ensures optimal hydraulic flow to all components, while the main pump has a maximum flow rate of 172 liters per minute. This configuration allows for swift and responsive movement of the arm, boom, and bucket.
The excavator features a maximum hydraulic working pressure of 24.5 MPa for the working hydraulic circuits, and the hydraulic pressure for the swing circuit is 21.1 MPa. This powerful hydraulic setup contributes to the bucket digging force of 54.8 kN and the arm digging force of 39.8 kN, providing excellent digging and lifting performance in various soil conditions.
Performance and Capabilities
The PC60-8 boasts a number of features that contribute to its strong performance and efficiency on the job site. It has an impressive max digging depth of 3,900 mm and a max digging radius of 6,190 mm, making it capable of reaching deeper trenches and wider areas compared to other machines in its class.
Its maximum swing torque is 56.6 kN, and the machine's travel speed ranges from 2.8 km/h to 4.5 km/h, offering adequate speed for transporting materials and maneuvering around job sites. The ground pressure of 28.4 kPa allows the PC60-8 to operate efficiently on soft soils and uneven terrains, providing a good balance between stability and power.
Body and Dimensions
The dimensions of the Komatsu PC60-8 are optimized for maneuverability and ease of transportation. With a total working weight of 6,180 kg, it is sufficiently compact for smaller spaces but still delivers the performance of a larger machine. The track width is 450 mm, which provides stability while digging, and the track gauge is 1,700 mm, ensuring the machine is well-balanced during operations.
The overall length is 6,035 mm, with an overall width of 2,225 mm and a height of 2,620 mm, making it a reasonably compact machine for tight job sites. The minimum ground clearance of 350 mm ensures the machine can traverse uneven surfaces without getting stuck or damaged. The minimum swing radius is 1,700 mm, which provides excellent maneuverability in confined spaces.
Oil Capacity
The Komatsu PC60-8 is equipped with ample oil capacity, including a fuel tank of 130 liters, a hydraulic oil tank of 95 liters, and a coolant capacity of 10 liters. The engine oil change volume is 12.5 liters, which is relatively low for a machine of its size, ensuring easy maintenance and quick servicing.
Work Equipment and Reach
The Komatsu PC60-8 features a bucket capacity ranging from 0.25 m³ to 0.37 m³, depending on the attachment. Its maximum dumping height is 4,925 mm, and the maximum vertical digging depth is 3,350 mm, making it effective for both digging and lifting operations in varying conditions. With an arm reach of 6,190 mm and a max digging height of 7,030 mm, this excavator is capable of handling most excavation tasks with ease.
The minimum rear swing radius is 1,750 mm, ensuring that the machine can work in areas with limited space, ideal for urban construction sites or cramped job sites.
Conclusion and Insights
The Komatsu PC60-8 is an efficient and reliable compact hydraulic excavator that offers excellent performance in a variety of applications. With its turbocharged engine, robust hydraulic system, and compact yet powerful design, it is well-suited for tasks ranging from digging and lifting to demolition and material handling.
When considering this model for purchase or use, the main advantages include its high digging force, strong lifting capacity, and smooth operation due to its advanced hydraulic system. Its small footprint allows it to be used in tighter spaces, making it ideal for urban environments or where space is limited.
Overall, the PC60-8 is a versatile machine that provides a high return on investment. With the right maintenance and operational practices, it can serve for many more years, offering a durable and efficient solution for excavation and construction needs.
