Detailed description of Komatsu PC70-7 excavator:

1. Basic parameters and core configuration

Tonnage and weight: 7-ton small excavator, machine working weight 7,300 kg.

Power system:

Engine: Equipped with Komatsu 4D95LE direct injection turbocharged water-cooled engine, rated power 40 kW (about 54 horsepower)/2100 rpm, displacement 3.26L, in line with National III emission standards, excellent fuel economy, theoretical fuel consumption of about 6-7 L/h.

Fuel tank capacity: fuel tank 130 L, hydraulic oil tank 90 L, engine oil replacement volume 11 L.

Bucket capacity: standard configuration 0.28-0.37 m³, support the selection of different buckets (such as narrow bucket, wide bucket) to meet diverse needs.

2. Core performance characteristics

Efficient operation capability

Hydraulic system: Komatsu CLSS closed load sensing hydraulic system, main pump flow 155 L/min, working pressure 24.5 MPa, precise and smooth movement, bucket maximum digging force 54.8 kN, bucket arm digging force 37.3 kN, suitable for small and medium-sized earthwork operations.

Multi-mode switching: supports economic mode (E0-E3 gear) and power mode (P gear), optimizing fuel consumption and operation efficiency.

Compact design and flexibility

Size advantage: The whole machine transportation size is 6080×2225×2590 mm, and the tail turning radius is 1750 mm, which is suitable for narrow space (such as municipal streets, indoor demolition) operations.

Travel performance: track width 450 mm, travel speed 2.8–4.5 km/h, climbing ability 70% (about 35°), ground clearance 350 mm, adapting to complex terrain such as mud and ramps.

Operation comfort and safety

Cab design: equipped with suspension seat, automatic air conditioning and 7-inch LCD monitoring screen, supporting multi-language display and fault diagnosis, and panoramic glass design provides a wide field of view.

Intelligent management: built-in EMMS health diagnosis system, real-time monitoring of oil temperature, pressure and other parameters, automatic alarm when abnormal.

III. Applicable scenarios

Municipal engineering: pipeline laying, greening construction, lane maintenance and other narrow space operations.

Farmland water conservancy: ditch excavation, land leveling and other light earthwork tasks.

Multi-function expansion: through the quick-change connector to adapt to the breaker, grab, ripper and other accessories to meet diverse needs (Note: hydraulic breaker pipeline is not standard, need to be optional).
