Second Hand Komatsu PC200 Excavator High Quality 20 Ton Operating Weight Well Condition Excavator

The Komatsu 200-7 excavator (model PC200-7) is a 20-ton medium-sized crawler excavator produced by Komatsu of Japan. It is widely used in earthworks, construction sites and mining operations. The following is a comprehensive description of its core features and performance:

1. Power and performance

Engine: Equipped with Komatsu SAA6D102E-2 direct injection diesel engine, rated power 107 kW (about 145 horsepower), displacement 5.883 L, water-cooled and 4-stroke design, powerful power and high stability.

Operation capacity: bucket digging force 149 kN, bucket arm digging force 145 kN, standard bucket capacity 0.8 m³, maximum digging depth 5.68 meters, maximum digging height 9.8 meters, maximum walking speed 12.4 km/h, suitable for a variety of complex working conditions.

Hydraulic system: Equipped with variable piston pump and optimized hydraulic circuit (main pump flow 2×214 L/min), it is sensitive and well coordinated, with low failure rate, but components such as high-pressure oil pipes are prone to leakage.

2. Design and comfort

Structural design: The working weight of the whole machine is about 20 tons, the transportation dimensions are 9.48×3.0×2.985 meters, and the track ground length is 3270 mm, providing good stability.

Driving experience: The cab is equipped with air conditioning and shock-absorbing seats, but the handle is heavy and the sitting position is high, which may cause fatigue after long-term operation. The external design of the air conditioning filter is easy to maintain.

3. Fuel economy and energy saving

Although the engine is powerful, the fuel consumption is high (such as about 300 liters of fuel consumed in 13 hours of continuous operation), and the operation needs to be planned reasonably to optimize fuel efficiency.

The hydraulic system can automatically adjust the flow pressure according to the load to reduce energy waste, and the intelligent control mode optimizes the engine output power.

4. Durability and maintenance

Reliability: Users report that the durability of the three major components (engine, hydraulic system, and structural parts) is outstanding, and some equipment has been running for nearly 20,000 hours without major repairs.

Maintenance cost: It is recommended to regularly replace engine oil, hydraulic oil, and filters, and check vulnerable parts such as tracks and pins.
