The XCMG XE900D is a 90-ton class heavy-duty mining crawler excavator manufactured by XCMG, China's premier construction machinery producer. This model features a standard bucket capacity of 4.1-6.0 cubic meters with an operating weight of 89,600 kg. Powered by an original imported American Cummins QSX15 engine delivering 399 kW at 2,100 rpm with Tier 3 emission compliance, it is designed for demanding large-scale mining operations with dimensions of 13,570×4,545×5,380 mm .
1.Powerful and Efficient PerformanceThe Cummins QSX15 6-cylinder engine generates 399 kW with 2,539 N·m torque at 1,400 rpm for heavy-duty mining operations. Its 15-liter displacement delivers strong power with low noise and fuel consumption. The Tier 3 emission compliant engine ensures environmentally friendly operation in rigorous mining conditions .
2.Advanced Intelligent Control SystemGenuine imported hydraulic components with reliable negative flow control system provide strong excavation capability. Independent cooling system automatically controls fan speed based on oil temperature, reducing energy consumption and noise. The fan can reversely rotate to conveniently clean dust from the cooler .
3.Durable Heavy-Duty StructureReinforced chassis with strengthened stringers, H-frame, track chains, and rollers significantly increases carrying capacity. Box-structured lightweight working device with solid forging at crucial positions reduces welding stress and defects. Stress analysis and fatigue life testing ensure sufficient strength and rigidity for heavy-duty excavation and mining .
This excavator excels in large-scale open-pit mining operations including coal, copper, iron ore, and hard rock excavation where 90-ton capacity and extreme durability are critical. It serves reliably in major infrastructure projects, quarry aggregate production, and deep foundation excavation requiring continuous heavy-duty performance. The XE900D has proven its capability with over 30,000 working hours in harsh mining environments, making it a trusted solution for mining contractors and heavy construction fleets worldwide .
