Product Description
Built for compact job sites and urban construction projects, this 2015 Doosan DX55-9C mini excavator delivers reliable performance across digging, grading, and utility work. With a 5.5-ton working weight and 0.18-0.21 m³ bucket capacity, it maneuvers efficiently in confined spaces while maintaining impressive digging capabilities—reaching 3.8m depth and 6.1m radius. The 4TNV94L engine generates 36.2 kW at 2100 rpm, providing consistent power for demanding tasks.
Hydraulic performance stands out with dual variable piston pumps delivering 2×57.8 L/min flow, producing 40.2 kN bucket digging force and 24.5 kN arm force. The 9.2 rpm rotation speed enables quick cycle times on grading and loading operations. Compact transport dimensions (5850mm length × 1930mm height) simplify mobilization between sites, while the 380mm track plates balance ground pressure and stability.
Currently located in Hunan, this machine arrives site-ready with 115L fuel capacity and 62L hydraulic tank for extended operation. Perfect for contractors handling excavation, trenching, and demolition work requiring precision in tight quarters.
