Comprehensive description of Komatsu PC120-8 excavator:

1. Core performance and configuration

Basic parameters

Tonnage: 12 tons, the working weight of the whole machine varies depending on the configuration, ranging from 11,498.6 kg to 12,560 kg.

Bucket capacity: The standard configuration is 0.5~0.65 m³, and some models are marked as 0.52 m³ or 0.7 m³, which may be related to different working conditions or configuration versions.

Operation range:

Maximum digging depth: 5,430~5,860 mm;

Maximum unloading height: 5,345~6,210 mm;

Maximum digging radius: 7,500~9,780 mm.

Power system

Engine model: Mainly equipped with Komatsu SAA4D95LE-5 4-cylinder turbocharged diesel engine, rated power 63~68.7 kW (about 84~92 horsepower), displacement 3.3 L, meeting Tier 3 or National III emission standards.

Fuel economy: Fuel tank capacity 247 L, hydraulic oil tank 90 L, support long-term operation.

Hydraulic system

Main pump flow: 242 L/min, working pressure 31.4~37.3 MPa, using closed load sensing system (CLSS) to improve compound operation efficiency.

Digging force: The maximum digging force of the bucket is 93.4 kN, and the digging force of the bucket arm is 67.5 kN, which is suitable for medium-intensity earthwork operations.

2. Design and operation features

Control and comfort

Cab: Equipped with panoramic glass windows and suspended seats, the operating field of view is wide, and some models support the KOMTRAX system to monitor the equipment status in real time.

Travel performance: Travel speed is divided into high and low gears (high speed 5.5 km/h, low speed 2.2~3.6 km/h), climbing ability 35° (70%).

Maintenance and reliability

The engine cooling system is water-cooled, and the hydraulic pipeline layout is reasonable for easy maintenance.

The original filter element and high-quality diesel need to be replaced regularly to avoid injector failure.

3. Model differences and market performance

Version differences

PC120-8M0: Some parameters show that the machine weight is 12 tons, the standard bucket capacity is 0.52 m³, and the rated power is 68.7 kW. It may be an optimized upgraded version.

Mixed engines: Some second-hand equipment is marked with the engine model S4D 105-5 or three 720D-25, which may be information errors or special configurations.

Market positioning

Applicable scenarios: municipal engineering (such as pipeline laying), earthwork operations and small and medium-sized construction sites, taking into account flexibility and efficiency.

IV. User evaluation and precautions

High efficiency and durability: The hydraulic system has a low failure rate and can maintain stable performance after long-term use.

Easy to operate: The intelligent control system and comfortable cab design enhance the user experience.
