두산 345

The Doosan DX345 is a high-performance medium-sized hydraulic excavator, designed for heavy-duty construction, mining, road construction and foundation engineering. With excellent power, stability and durability, it can efficiently handle various harsh working conditions and meet the high productivity needs of contractors. Powered by a Doosan DE12TIA-C2 diesel engine, the DX345 delivers a rated output of 188 kW at 1800 rpm, ensuring strong power output while optimizing fuel consumption. It complies with Euro Ⅱ emission standards (some versions meet National Ⅲ/GB20891-2014 Stage Ⅲ), achieving a balance between environmental protection and performance. Equipped with an advanced hydraulic system, it has a main pump flow of 2×266 l/min and an auxiliary hydraulic flow of about 120-150 l/min, enabling smooth, precise and responsive operation of various attachments such as buckets, breakers and grapples. The excavator offers two travel speed modes: 5.0 km/h (high gear) for quick site relocation and 3.2 km/h (low gear) for strong traction in complex terrain. With an operating weight of 34,200 kg, the DX345 features a stable working platform. Its standard bucket capacity is 1.6 m³, with optional capacities ranging from 1.4 to 1.9 m³ to adapt to different material handling scenarios. The standard track width is 600 mm (700 mm optional), which effectively distributes ground pressure and reduces soil disturbance. The transport dimensions are 11,090 mm (L) × 3,200 mm (W) × 3,450 mm (H), allowing for easy transportation between job sites without special permits. The ergonomically designed cab is equipped with a comfortable suspension seat and intuitive controls, reducing operator fatigue during long working hours. The reinforced undercarriage, boom and arm ensure long-term structural integrity, while accessible maintenance points minimize downtime and service costs.
