Product Features
Original Cummins QSM11 Engine - As the core power of this 50 ton mining excavator, it is equipped with a 6-cylinder inline supercharged and intercooled Cummins QSM11 engine (displacement 11L, rated power 280kw/rpm). This engine delivers ample power reserve and strong torque, ensuring no stalling during long-term heavy mining operations, while its excellent fuel economy effectively reduces long-term operating costs for mining customers.
Advanced Electro-hydraulic Control System - Equipped with 2 variable piston pumps + 1 gear pump and advanced electro-hydraulic control, this 50 ton mining excavator boasts fast action response and smooth compound operations. Paired with a 2.5-2.8m³ bucket capacity, it significantly improves digging and loading efficiency, helping customers save project construction time and reduce labor costs.
Mining-Grade Reinforced Structure - To withstand harsh mining conditions, the boom, arm, frame, and crawler of this Shitian 50t excavator are fully strengthened with high-strength steel. This design enhances impact resistance and wear resistance, allowing the 50 ton mining excavator to adapt to long-term rock stripping and extend equipment service life, reducing replacement costs for customers.
Stable Travel & High Safety - With an operating weight of 49600 Kg, the heavy-duty chassis of this 50 ton mining excavator is matched with widened crawler tracks (track width 3360mm), featuring low ground pressure (81.9KPa). This combination ensures strong passing ability and high stability, allowing safe and stable operation on steep slopes, soft ground, and other complex mining sites, minimizing operation risks.
Convenient Maintenance Design - The 50 ton mining excavator features centralized maintenance points, a large-opening hood, and easy access to key components. This design makes daily inspection and maintenance faster and more convenient, effectively reducing equipment downtime, improving attendance rate, and ensuring continuous mining operations.
