PRODUCTS DESCRIPTION
The DEVELON DX305HD hydraulic excavator is built for extreme working conditions, setting new benchmarks in the 30-ton class with its advanced power system, reinforced structural design, and intelligent operation technology. Powered by the Divanlen D108 high-performance engine, the DX305HD delivers 204 kW of maximum output—7% higher than the previous generation—while meeting strict National IV emission standards. Its EPOS-10I intelligent control system automatically adapts to working conditions through four operating modes, ensuring both efficiency and durability. Combined with a 1.85m³ ultra-large bucket and a maximum digging depth of 7,200mm, this machine excels in mining, large-scale earthmoving, and ultra-deep excavation projects. The heavy-duty undercarriage, wide 600mm tracks, and reinforced chassis increase stability and impact resistance, while fuel-saving technologies optimize hydraulic flow for over 10% better efficiency. Designed with operators in mind, the DX305HD integrates a 10-inch touchscreen, panoramic cameras, and a suspension seat for comfort and safety, making it an ideal choice for high-intensity environments.
