Japan Original Used Excavators Competitive Price Used Komatsu PC300 Excavator Crawler Digger Machine

Detailed description of Komatsu PC300 excavator:

1. Core features

High efficiency and environmental protection

Equipped with Komatsu SAA6D114E series engine (such as PC300LC-8M0 model is SAA6D114E-3), rated power covers 187 kW to 254 kW (251-341 horsepower), displacement 8.27L, meet Tier 3 or Tier 4 emission standards, and take into account both power and environmental protection needs.

Standard bucket capacity 1.4-1.6 m³, optional up to 2.0 m³ (high-end cycle model), suitable for high-intensity operations such as mining and earthwork.

Travel speed is adjustable in three gears (3.2/5.5 km/h), and the rotation speed is 9.5 rpm, which adapts to complex terrain and efficient operation requirements.

Reliability and durability

The hydraulic system adopts a variable piston pump, the maximum flow of the main pump is 535 L/min, and the working pressure is 37.3 MPa to ensure operation stability.

The boom length is 6470 mm, the arm length is 3185 mm, and it is made of high-strength steel to improve fatigue resistance.

The track ground length is 3700 mm, the track gauge is 2590 mm, and the ground pressure is 56.3-77.5 kPa, which enhances the stability on complex ground.

Safety and operating comfort

The cab is equipped with an anti-rollover structure, fully automatic air conditioning and noise reduction device. The operating interface conforms to the ergonomic design to reduce fatigue.

The standard KOMTRAX system monitors the equipment status in real time and optimizes the maintenance plan.
