Used Komatsu Excavator PC450LC-8 with Good Original Quality and Affordable Price

The Komatsu PC450-8 excavator is a large crawler hydraulic excavator produced by Komatsu Group of Japan. It is designed for heavy-duty operations and combines high productivity, fuel economy and safety. It is widely used in engineering fields such as mining, road construction, and land reclamation. The following is a detailed description of its core features and technical parameters:

1. Core features

Efficient production and environmental protection

Adopting a large heavy-duty bucket (capacity 2.1-2.4 cubic meters) to meet the needs of large workloads and improve efficiency.

Equipped with Komatsu SAA6D125E-5 engine, rated power 257kW/1900rpm, displacement 11.04L, combined with turbocharging and electronic speed control technology, it has both high power output and fuel economy.

Adjustable crawler track gauge design (2392mm when retracted, 2890mm when expanded) enhances operation stability and adapts to complex terrain.

Reliability and durability

The hydraulic system uses high-pressure series filters and high-efficiency filter materials to reduce the risk of pollution and extend the oil and filter replacement cycle.

Equipped with an equipment management monitoring system to monitor the machine status in real time and reduce the failure rate.

Safety design

The cab adopts a tubular structure to enhance protection, equipped with anti-skid plates, hydraulic locking rods and large handrails to improve operational safety.

Anti-rollover protection system and emergency brake device to ensure safe operation under harsh working conditions.
