Japan Komatsu PC240-8 Crawler Excavator, Low Price Komatsu 24 Tonne Excavator PC240 Crawler Excavator Original

Komatsu 240-8 excavator is a medium-sized hydraulic excavator produced by Komatsu of Japan. It is widely used in earthwork, mining operations, building demolition and other fields.

1. Basic parameters and performance

Power system

Engine power: There are large differences under different configurations. The standard version is 110 kW (about 150 horsepower), while the net power of the upgraded version 240-8mo can reach 185 kW (250 horsepower).

Hydraulic system pressure: Rated working pressure is 34.3 MPa (343 kg/cm2), providing efficient hydraulic output.

Operation capacity

Working weight: 22.6 tons for the standard version and 23.3 tons for the upgraded version 240-8mo.

Bucket volume: 1.0 m³ for the standard configuration, and 0.82-1.2 m³ for the 240-8mo.

Digging depth/radius: The maximum digging depth of the standard version is 5.88 meters, and the 240-8mo can reach 7.99 meters through the extended arm configuration.

Digging force: Maximum bucket digging force 155 kN (standard version) to 148 kN (upgraded version).

Walking and adaptability

Traveling speed: 2.5-5.5 km/h, adaptable to complex terrain.

Climbing grade: Maximum 35 degrees, with strong terrain adaptability.

2. Technical highlights

Electronic control injection system

Position-controlled distribution pump: The injection amount and timing are controlled by electromagnets and sensors in a closed loop to improve fuel efficiency and reduce emissions.

Time-controlled distribution pump: The oil overflow ring is cancelled and a high-frequency solenoid valve is used to directly control the injection on and off, which simplifies the structure and responds faster.

Electronic control pump nozzle technology: The injection pressure is as high as 200 MPa, and the high-pressure oil pipe design reduces pressure loss and improves combustion efficiency.

Hydraulic system optimization

The closed hydraulic circuit design is adopted, and the action coordination is good, which is especially suitable for high-frequency soil throwing, loading and other operations. Users report that the loading speed in P mode (high-efficiency mode) is better than that of similar models.

Durability and maintenance

Long-term user use cases show that this model can run stably for more than 20,000 hours with proper maintenance, and the main wear parts are chains and hydraulic pipes. Original accessories are recommended, and aftermarket parts may affect performance (such as the problem of the rotating system running away).

III. Application scenarios and configuration expansion

Extended arm configuration

Optional two-stage or three-stage extended arms, with a total length of up to 18 meters (10 meters for the main arm + 8 meters for the small arm), suitable for deep foundation pit excavation, high-rise building demolition and other scenarios.

The extended arm has a built-in buffer plate to enhance the structural strength and adapt to 20-25 ton operation requirements.

Multi-functional adaptability

Supports accessories such as breaker hammers and ripper, but users report that long-term crushing operations may increase the load on the hydraulic system, and attention should be paid to oil temperature control.
