Product Description
Powered by Komatsu's proven 4D88E-6 engine delivering 28.5kW at 2400 RPM, this PC55MR-2 combines compact dimensions with serious digging capability. Advanced hydraulic systems generate 39kN of rod digging force while maintaining precise control for detailed excavation work.
Engineering excellence defines this 5-ton class machine. The PC55MR-2 series represents Komatsu's commitment to reliability, featuring water-cooled operation and optimized fuel efficiency through its 2.2L displacement engine. Compact transport dimensions of 5550mm length enable easy jobsite mobility without sacrificing performance.
- Maximum digging depth: 3800mm with 6070mm reach
- Zero tail swing design with 1060mm rear turning radius
- Robust 400mm track plates for superior ground contact
- 65L fuel capacity for extended operation cycles
- 30.3 KPa ground pressure minimizes surface damage
Located in Luzhou, Sichuan, this 2016 unit demonstrates Komatsu's joint-venture manufacturing standards. Ideal for urban construction, utility work, and confined space applications where precision meets productivity.
