Product Description
Engineered for demanding excavation operations, this PC450-8 represents Komatsu's commitment to hydraulic excellence and mechanical precision. Powered by the robust SAA6D125E-5 engine delivering 257 kW at 1900 rpm, this 45-ton excavator combines an 11.04L displacement with water-cooled, turbocharged efficiency. The advanced hydraulic system features dual axial plunger walking motors and a single rotary motor, supported by a maximum main pump flow of 690 l/min, ensuring responsive control across all functions.
Performance specifications demonstrate superior capability:
- Bucket digging force: 278 kN with 2.1 m³ capacity
- Maximum digging reach: 12,005 mm with 7,790 mm depth
- 7,060 mm boom and 3,380 mm arm configuration
- Working weight: 45,125 kg with optimized 84.1 kPa ground pressure
- 9.1 rpm rotation speed for efficient cycle times
Located in Hefei, Anhui, this joint-venture manufactured machine maintains Komatsu's Japanese engineering standards. The PC450-8 series integrates electronic speed regulation with pilot hydraulic controls (3.2 MPa), providing operators with precise command over bucket, arm, and boom cylinders. With 650L fuel capacity and comprehensive servi
