斗山 225

Doosan 225 Excavator is a benchmark model of 20-ton medium-sized hydraulic excavator. Specially built for various working conditions such as mining, municipal infrastructure, road construction and earth excavation, it has become a cost-effective main equipment in engineering construction by virtue of Doosan's independent power hydraulic system, heavy-duty durable design and high-efficiency fuel-saving performance. The whole machine is equipped with Doosan original DL06/DE08TIS in-line 6-cylinder turbocharged engine with a rated power of up to 127.9kW. It features strong power output and is compatible with emission standards such as China IV/Stage IIIA. Combined with the exclusive E-EPOS electronic power optimization system, it realizes precise synchronization between the engine and the hydraulic system, distributes power on demand, greatly reduces fuel consumption, and balances operation efficiency and operating costs. It has outstanding core operation performance, standard equipped with a 1.05m³ large-capacity bucket with a bucket digging force of 152kN and an arm digging force of 108kN, which can easily cope with heavy-duty excavation operations; the maximum digging depth is 6592mm and the maximum digging radius is 9873mm, with a wide operation coverage, suitable for various digging, loading and leveling needs. The dual variable piston main pump provides a large flow rate of 2×212L/min, the hydraulic circuit pressure reaches 34.3MPa, the action response is sensitive, and the compound operation is smooth. The high and low double-speed travel of 5.7/3.1km/h makes transfer and operation more efficient. The 10.5rpm rotation speed is combined with wet multi-disc braking, which makes rotation stable and braking reliable. The whole machine adopts a heavy-duty structural design, with reinforced boom, arm and chassis frame, combined with thickened track shoes and high-rigidity slewing platform, with outstanding impact and wear resistance, and can adapt to continuous heavy working conditions such as mining; the cab is equipped with a shock-absorbing suspension seat and a multi-functional color LCD display, with optional heating and air conditioning and reverse image, with a wide field of vision and comfortable operation, which greatly reduces operator fatigue. At the same time, it has a self-diagnosis function and centralized maintenance points, with convenient daily maintenance, strong versatility of parts and lower maintenance costs. From basic construction to heavy-duty operations, Doosan 225 Excavator balances power, efficiency and durability, and adapts to the operation needs of different construction scenarios. Coupled with Doosan's perfect global agent service network and original parts supply, it provides a strong guarantee for the long-term stable attendance of the equipment, and is an optimal equipment for reducing costs and increasing efficiency in engineering construction.
